TO OPERATOR’S ATTENTION!
1. Before you start operating the tractor, carefully read this Manual and strictly follow
all instructions herein.
2. Use the climatic diesel fuel according to the Manual. Reduce the motor oil
changeover intervals by half, if the sulfur content in the fuel is below 1%.
3. Do not operate the diesel engine at the idle speed more than 15 minutes.
4. Remember that the engine can be only started when the GB lever is in the extreme
left position (in the position of engaging the I or II gear range).
5. Use the synchronous drive of the rear PTO only when the tractor unit speed does
not exceed 8 km/h. Otherwise, severe damages in the tractor power train are
possible.
6. Operate the tractor on the direct gear only with the high gear range engaged (range
II).
7. The tractor cab is equipped with a single seat, only operator is allowed to be in it.
8. When the tractor is shipped from the manufacturer factory, some parts of the tractor
are put into the SPTA box, tool box or cab. Install them onto the tractor on your own.
9. When commissioning new batteries, remove the sealing film from the vent holes or
cut off the bosses on the plastic caps.
10. Do not operate the tractor when the clutch is not totally disengaged or is engaged.
11. When starting movement, make sure that the hand-operated reserve parking brake
is disengaged.
12. When using the tractor without driveshafts, shift the FDA lever to the position
“forced”.
13. Do not work on the tractor in closed rooms without adequate ventilation (air
exchange). Exhaust gases can kill you!
14. Towing the tractor with front wheels lifted is strictly forbidden. Failure to observe this
rule may result in a FDA drive failure and emergency situation.
15. Never lift the front part of the tractor by the towing shackle. Use the shackle for
towing only.
16. The manufacturer continually improves the tractor, due to which there could be
some modifications of the design of some components and their operating rules,
which are not reflected in this Manual.

Section A. Safety precautions Belarus- 510/512 —Operating manual
• Before lifting and lowering an agricultural implement, as well as when making turns, make sure that there is no
hazard to hit someone or run over an
obstacle.
• During transport journeys with
mounted machines or implements, always use the mount lock in the raised
position (for tractors with an autonomous
power cylinder).
• The driveshaft transmitting rotation from the tractor PTO shaft to the aggregated tools of the unit must be guarded.
• Ensure the correct installation of
any additional equipment or auxiliary devices, and make sure that they are designed for use with your tractor. Remember that your tractor, if improperly used,
can be dangerous both for you and for
other persons. Do not use equipment
that is not intended for installation on the
tractor.
• To avoid a tipover, exercise caution when driving the tractor. Choose a
safe speed appropriate to road conditions, especially when driving on rough
terrains, when driving over ditches,
slopes and making sharp turns.
• When working on slopes, increase
the tractor wheel track to the maximum.
• Do not make sharp turns with a
full load and at a high speed.
• When using the tractor for transportation works:
− increase the tractor wheel truck to
1,800 mm (70") min.;
− interlock the brake pedals, check
and adjust as necessary the brakes for
simultaneous action;
− check operation of the parking
brake;
− check the condition of light and
sound signal equipment;
− transportation trailers must have a
solid connection and, in addition, connect a safety chain or rope;
− never drive downhill by coasting
(out of gear), drive at the same gear both
downhill and uphill;
− do not work with a trailer without independent brakes if its weight exceeds
half of the total actual weight of the tractor. The faster you drive and the greater
is the towed weight, the greater must be
the safe distance;
− disconnect the FDA in order to
avoid excessive wear of the drive parts
and tires;
− do not use the rear axle DL at a
speed exceeding 10 km/h and when
making turns;
− the PTO must be off and the simultaneous/independent drive shifter arm
must be in the neutral position;
− do not stop the tractor on slopes. If
you want to stop, engage the 1st gear
and fully engage the parking brake.
• When working with equipment
driven from the PTO, disengage the PTO
before disconnecting the equipment,
stop the diesel engine, make sure the
PTO shaft end is fully stopped.
• Do not wear loose clothing when
working with the PTO or near rotating
equipment.
• When working with stationary machines driven from the PTO, always engage the parking brake and chock rear
wheels from the front and from the rear.
Make sure that the machine is reliably
secured.
• Make sure that the PTO shaft end
guard is installed, and when the PTO is
not used, install the PTO shaft end cap
to place.

Section A. Safety precautions Belarus- 510/512 —Operating manual
• Do not clean up, adjust or service
the equipment driven from the PTO with
the diesel engine running.
Safety requirements for maintenance
service
• Never refuel the tractor with the
diesel engine running.
• Do not smoke when refueling the
tractor.
• Do not fill the fuel tanks completely. Leave a space for fuel expansion.
• Never add gasoline or blends to
diesel fuel. Such combination may result
in higher hazard of flame or explosion.
• Make proper use of summer and
winter grades of fuel. To reduce the
amount of night condensate, refill the
fuel tank at the end of each working day.
• Refill the tractor only with oils and
greases recommended by the manufacturer. Use of other lubricants is strictly
prohibited!
• All operations related to cleaning
the engine and the tractor, preparation to
work, maintenance, etc. must be performed with the engine off and the tractor
brake engaged.
• The cooling system operates under pressure maintained by a valve installed on the filler cap. It is dangerous
to remove the cap on a hot engine. To
avoid burns of face and hands, take special care when opening the radiator cap
equipment, in good condition to ensure
your safety and that of the surrounding
people.
• Do not modify the tractor or any of
its constituent parts without approval
from you dealer and manufacturer.
Safety requirements for operation and
maintenance of electrical equipment
• To avoid damages to semiconductor devices and resistors, observe the
following precautions:
− do not disconnect the storage battery terminals when the diesel engine is
running. This will result in peak voltage
in the charging circuit and unavoidable
damage of diodes and transistors.
− do not disconnect the electrical
wires until the diesel engine stops and all
electrical switches are switched off;
− do not cause a short circuit due to
faulty connection wires. A short circuit or
wrong polarity will cause damage to the
diodes and transistors;
− do not connect the storage battery
to the electrical system until terminals
and voltage are checked for the polarity;
− do not check availability of electric
current by sparking as it will result in an
immediate breakdown of transistors.
Hygiene requirements:
• If duration of continuous work on
the tractor exceeds 2.5 hours per a working shift, use personal protection equipment to muffle noise as per State Standard ГОСТ 12,4.051-87 (such as ear protectors, ear plugs)
on a hot engine, put a thick cloth onto
the cap first and put on a glove.
• To avoid burns, be careful when
draining the coolant from the cooling system, hot oil from the diesel engine, hydraulic system and transmission.
• Exercise caution while servicing
storage batteries as electrolyte causes
burns in case of skin contact.
• To avoid risk of explosion, do not
allow a source of open fire near the fuel
system of the engine and batteries.
• Keep your tractor and its equipment, especially the brakes and steering
Fire safety requirements
• The tractor must have firefighting
tools such as a shovel and a fire extinguisher. Working on the tractor without
fire-fighting equipment is prohibited.
• The tractor park sites, fuel and
lubricant storage places must have a
surrounding plowed strip with a width of
3 m min. and be provided with firefighting means.
• Avoid contamination of the manifold and silencer with dust, fuel, straw,
etc.
13
Page 11
Section A. Safety precautions Belarus- 510/512 —Operating manual
• Do not allow straw to be taken up
by rotating parts of the machines attached to the tractor.
• When rinsing parts and assemblies with kerosene or gasoline, take
precautions to exclude ignition of vapors
of the rinsing fluid.
• Do not operate the tractor in places of high fire hazard with the hood and
other protective devices removed from
hot parts of the engine.
• Do not use open fire to heat up oil
in the diesel engine pane, to burn out
contamination of the radiator core.
• If there appears a seat of fire,
dump sand over it, cover with tarpaulin,
sackcloth or any other dense cloth. Use
a carbon-dioxide fire extinguisher. Do not
extinguish burning fuel with water.
• When the engine is running, keep
inflammable materials away from the exhaust manifold and muffler.
• When making hay and straw or
working in places with high fire hazard,
use spark arresters in the exhaust system complete with a silencer or separated from it.

Gearbox
The gearbox (GB) is an element of the tractor transmission serving to change the
transmission gear ratios and reverse the tractor movement, thus achieving the required
speed range of the tractor (see Table 1), as well as for long-term disengagement of the
engine and the tractor propeller.
Besides, the GB design provides driving the front drive axle (FDA) of the tractor
and synchronous rear power take-off shaft (PTO).
The BELARUS-50/52 tractors and their modifications have a mechanical fixed-ratio
dual-range 9F/2R GB with a central position of the GB control lever, the design and operation of which are described below.

Section B. Specifications Belarus-510/512 Operating manual
1.1 GB design
The GB (Fig. 1 and 2) consists of the mechanical gears unit and GB control.
1.1.1 Mechanical gears unit
The mechanical gears unit of the GB consists of the concentric input (31) and output (6) shafts located in the
GB housing (27) (Fig. 1)
*
, as well as an intermediate shaft (29)
parallel to them and the shaft of 1st gear and reverse (24) (Fig. 2).
The input shaft (31) (Fig. 1) is mounted on two ball bearings one of which is placed
in the body (32) on the front wall of the GB housing (27). The second one is in the boring
of the output shaft (6). On the input shaft, a double-wheel drive pinion of 4th and 5th gears
(1) and a drive pinion of 3rd and 6th gears (5) with possibility of axial sliding movement
along the shaft splines are installed.
The output shaft supports (6) (Fig. 1) are two tapered roller bearings, one located in
the GB housing boring (27), and the second in the body (14) installed in the boring of the
rear wall of the GB housing (27). Structurally, the output shaft is made as one piece with
the driven pinion of Ist stage of the range reducer. The gear ring is located cantilevered in
front of the output shaft (6). Between the supports of the output shaft, the driven pinion of
IInd stage of the range reducer (16) is installed fixed on the splines, which is also the drive
pinion of the rear PTO synchronous drive. On the rear arm of the output shaft, the drive
gear (15) of the rear axle final drive (small bevel pinion) is installed fixed on the splines.
On the intermediate shaft (29), fixed on the splines are installed the double-wheel
driven pinion of 5th and 8th gears and reverse gears (26), driven pinion of 4th and 7th
gears (25), and driven pinion of 3rd and 6th gear (24), on the hub of which the doublewheel intermediate pinion (23) is freely rotating on needle roller bearings, being in constant
mesh with the pinion (22) (Fig. 2) installed on the shaft of 1st gear and reverse gears (24).
On the intermediate shaft (29) (Fig. 1), with the possibility of axial movement the drive pinion (22) of Ist stage
of the range-reducer is installed.
The front support of the intermediate shaft (29) is a ball bearing located in the body
(30) of the front wall of the GB housing (27). The rear support of the intermediate shaft is a
bronze bushing installed in the boring of the drive pinon (21) of IInd stage of the rangereducer.
The driven pinion of IInd stage of the range-reducer (21) is freely rotating on two
bearings located in the body (20) installed in the boring of the rear wall of the GB housing
(27). The pinion (21) has an inner and outer gear rings, as well as cams located on its rear
end, which serve to synchronously drive the rear PTO. In the boring of the pinion (21), the
seat (18) with bronze bushing is fixed with a pin, which is the rear support of the inner
shaft (17). Outside on the pinion (21), the impeller (19) is fixed, which by intensive spraying improves lubrication of the pinions of the final drive and the rear axle differential of the
tractor.
The 1st gear and reverse shaft (24) (Fig. 2) is installed on two ball bearings located
in the GB housing borings. In the front of the shaft (24) on splines, the sliding pinion (23) of
hill-climbing gears and reverse gears is installed. Backward movement of the sliding pinion
(23) up to meshing with the pinion (25) (Fig. 1) provides forward hill-climbing gears, and
forward movement up to meshing with the intermediate pinion of reverse motion (26) (Fig.
2) provides reverse gears. The intermediate reverse pinion (26) is installed on the axle
(25) and is freely rotating on it on a needle roller bearing. The pinion (26) is in constant
mesh with the smaller gear ring of the double-wheel gear (26) (Fig. 1).

At the rear part of the shaft (24) (Fig. 2), fixed on its splines, the driven pinion of hillclimbing gears and reverse gears (22) installed, which is constantly meshed with the
smaller gear ring of the pinion (23) (Fig. 1) of the intermediate shaft (29).
On the right side of the GB of the tractors with FDA drive, the axle (27) is installed in
the GB housing borings, on which on two tapered roller bearings the FDA drive pinion (28)
is freely rotating. Power is taken off at the FDA from the driven pinion of Ist stage of the
range reducer (6) (Fig. 1), with which the pinion (28) (Fig. 2) is constantly meshed.
On the front wall of the GB housing (27) (Fig. 1), concentrically to the intermediate
shaft (29), the seat (28) is installed, inside of which the inner shaft front bearing (17) is located.
On the right and left sides of the GB housing, there are windows (Fig. 2). The left
window is closed with the cover (17), in which there is a dipstick (18) to control the oil level. The tractors without an FDA drive have the right window closed with the cover (14), and
the tractors with the FDA drive have the cover (14) removed and the window closed by the
FDA drive transfer box housing (see section).
To drain oil when changing it, a hole is provided in the bottom of the GB housing,
closed with the plug (16).
1.1.2 GB control
The GB control consists of the forks housing (3) (Fig. 1) and the GB control cover
(11) that are installed on the upper plane of the GB housing (27) and bolted to it.
The forks housing (3) (Fig. 1 consists of the fork of 1st gear and reverse gears (19)
(fig. 2), the fork of 3rd and 6th gears (20), the fork of 4th and 5th gears (12) and the range
reducer rod (13), the rails of which are installed in the groove of the housing (1) and can
move along the groove. On the upper surfaces of the rails, there are transverse holes in
which the spring-loaded balls of the latches (10) are inserted, which provide locking of the
forks rails and reducer rail in the desired positions, as well as prevent spontaneous disengagement of the gears under load.
The rod (13) is connected with the shaft (9) (Fig. 1), on which the fork (8) is fixed
that moves the drive pinion of Ist stage of the range reducer (22).
The forks and range reducer rails are separated by three lock strips (11) (Fig. 2).
The strips (11) are installed in the housing (1) fixed and exclude simultaneous movement
of several rails by the gear shifter lever (7) (Fig. 1). When a gear is engaged, the lock
strips (11) lock the gear shifter lever (7) (Fig. 1) in the rail groove of the fork of the gear
engaged.
The GB control cover (11) consists of the cover (21) (Fig. 2), on the upper surface
of which the spherical bearing (6) of the gear shifter lever (7) (Fig. 1) is bolted. When
swinging, the gear shifter lever (7) directly affects the rails in the forks housing (3), causing
their displacement and, consequently, engagement or disengagement of the selected gear
or range in the GB.
To avoid excessive swinging of the gear shifter lever (7), as well as to clearly direct
its motion, the restrictive plate serves (12), which is bolted to the cover (11).
The GB design provides an engine start lock when a gear is engaged in the GB. On
the right side of the cover (21) (Fig. 2), the housing is installed (2) bolted to it. In the housing (2), the axle (5) of the spring-loaded rocking frame (7) is located. The ring hole of the
frame (7) envelops the gear shifter lever (7) (Fig. 1). At that, rocking of the lever (7) results
in a corresponding movement of the frame (7) (Fig. 2), the axle flat (5) of which affects the
diesel start lock sensor (4) mounted in the threaded hole of the housing (2).
Triggering of the engine start lock is adjusted by the shims (3) located under the
24

sensor (4).
1.2 GB operation
The 9F/2R GB design provides 4 forward gears and one reverse gear, each of them
can be engaged on the both range reducer stages, and one direct forward gear, at engagement of which the input (31) (Fig. 1) and output (6) shaft are rigidly linked by the drive
pinion of 3rd and 6th gears (5) acting as a gear-type coupling at that.
The GB gears and ranges are engaged by a single GB control lever (7) as per the
diagram (Fig. 3). Selection of gears in the GB is preceded by selection of the desired
range of the reducer.
Gears and ranges are switched only when the tractor stopped and the clutch pedal
is pressed on.
To select and engage a reducer range, the operator shifts the gear shift lever (7)
(Fig. 1) from the neutral position to the range-reducer position (Fig. 3). Further, to engage
the Ist reducer stage, the operator shifts the GB control lever (7) (Fig. 1) backwards (Fig.
3). At that, the gear shifter lever (7) (Fig. 1), acting on the reducer rail (13) (Fig. 2), moves
it and its associated roller (9) (Fig. 1) with the fork (8) forward. The drive pinion of Ist reducer stage (22) controlled by the fork (8) moves along he intermediate shaft splines (29)
and engages with the driven pinion (6) of Ist range reducer stage.
To engage the IInd reducer stage, the operator shifts the GB control lever (7) (Fig.
1) in the range reducer position forward (Fig. 3). At that, the gear shifter lever (7) (Fig. 1),
acting on the reducer rail (13) (Fig. 2), moves it and its associated roller (9) (Fig. 1) with
the fork (8) forward. The driven pinion of Ist reducer stage (22) controlled by the fork (8)
moves along he intermediate shaft splines (29) and engages with the inner gear ring of the
drive pinion (21) of IInd range reducer stage, linking it to the intermediate shaft (29). The
pinion (21) is in constant mesh with the driven pinion of the IInd range reducer stage (16).
At the IInd range reducer stage, rotation from the intermediate shaft (29) is transmitted to the output shaft (6) with deceleration less than at the Ist stage.
In the GB range reducer, there is no neutral position of the drive pinion of the Ist reducer stage (22) (Fig. 1), therefore either the Ist or the IInd stage is always turned on in the
range reducer.
To engage the 1st or 2nd forward or reverse gear, the operator shifts the GB control
lever (7) (Fig. 1) to the extreme left position (Fig. 3) being the position of hill-climbing gears
and reverse gears. Further, to engage the 1st or 2nd forward gear, the operator shifts the
GB control lever (7) (Fig. 1) forward (Fig. 3). At that, the gear shifter lever (7) (Fig. 1), acting on the rail of the fork of the 1st gear and reverse gear, moves the fork (19) (Fig. 2)
backward. The sliding pinion of 1st gear and reverse motion (23) controlled by the fork (19)
engages with the driven pinion of 4th and 7th gears (25) (Fig. 1), and power in the GB is
transmitted to the ?GB intermediate shaft (29) through the pinions (5), (23), (22) (Fig. 2),
(23) and (25) (Fig. 1).
To engage the 1st or 2nd reverse gear, the operator shifts the GB control lever (7)
(Fig. 1) to the position of hill-climbing gears and reverse gears backward (Fig. 3). At that,
the gear shifter lever (7) (Fig. 1), acting on the rail of the fork of the 1st gear and reverse
gear, moves the fork (19) (Fig. 2) forward. The sliding pinion of 1st gear and reverse motion (23) controlled by the fork (19) engages with the intermediate pinion of reverse gear
(26) being in constant mesh with the lesser gear ring of the double-wheel pinion of 5th and
8th gears (26) (Fig. 1). At the reverse gear, power flow in the GB is transferred to the intermediate shaft (29) through the pinions (5), (23), (22) (Fig. 2), (23), (26) and (26) (Fig. 1).
To engage the 3rd and 6th, or 9th (direct) gear, the operator shifts the GB control
25
Page 23
Section B. Specifications Belarus-510/512 Operating manual
lever (7) (Fig. 1) to the respective positions of those gears (Fig. 3). Further, to engage the
3rd (6th) gear, the operator shifts the GB control lever (7) (Fig. 1) to the position of the said
gears backward (Fig. 3). At that, the gear shifter lever (7), acting on the rail of the fork of
4th and 5th gears, moves the fork (20) (Fig. 2) forward. The sliding pinion of 3rd and 6th
gears (5) controlled by the fork (20) (Fig. 1) engages with the driven pinion of 3rd and 6th
gears (24). By the emerged mesh, power is transferred to the GB intermediate shaft (29).
To engage the 9th (direct) gear, the operator moves the GB control lever (7) (Fig. 1)
from the position of the 3rd (6th) and 9th (direct) forward gears (Fig. 3). At that, the gear
shifter lever (7), acting on the rail of the fork of 3rd and 6th gears, moves the fork (20) (Fig.
2) forward. The sliding pinion of 3rd and 6th gears (5) controlled by the fork (20) (Fig. 1)
engages with the inner gear ring of the output shaft (6), rigidly linking the input (31) and
output (6) shafts.
The 9th (direct) gear must be engaged when the IInd range reducer stage is engaged (Fig. 3).
shaft speed (29) (Fig. 1) less than the Ist stage.
This will avoid a loud noise in the GB, since the IInd reducer stage has an intermediate
To engage the 4th (7th) or 5th (8th) gear, the operator shifts the GB control lever (7)
(Fig. 1) to the respective positions of those gears (Fig. 3). Further, to engage the 4th or 7th
gear, the operator shifts the GB control lever (7) (Fig. 1) to the position of the said gears
forward. At that, the gear shifter lever (7), acting on the rail of the fork of 4th and 5th gears,
moves the fork (12) (Fig. 2) and the drive pinion unit of 4th and 5th gears (1) controlled by
it (Fig. 1) backward. The smaller gear ring of the unit (1) engages with the driven pinion of
4th and 7th gears (25). By the created mesh, power from the input shaft (31) is transferred
to the GB intermediate shaft (29).
To engage the 5th or 8th gear, the operator shifts the GB control lever (7) (Fig. 1) to
the position of the said gears backward (Fig. 3). At that, the gear shifter lever (7), acting on
the rail of the fork of 4th and 5th gears, moves the fork (12) (Fig. 2) and the drive pinion
unit of 4th and 5th gears (1) controlled by it (Fig. 1) forward. The larger gear ring of the unit
(1) engages with the driven pinion of 5th and 8th gear (26). By the created mesh, power
from the input shaft (31) is transferred to the GB intermediate shaft (29).

tanks.
2. Check tightening and retighten the
external fastening junctions.
3. Run in the tractor on light transport
and field works (harrowing, cultivation, sowing, etc.), gradually increasing the load at different gears.
4. Do not overload the engine, do not
allow fuming or drop of the rotational
speed. The overload symptoms are
abrupt drop of the engine speed,
fuming and failure to respond to
higher fuel feed.
5. The operation of the tractor at very low
gear with small load at high engine
speeds will result in excessive fuel
consumption. Correct selection of a
gear for each particular work provides
fuel saving and reduces engine wear.
6. Regularly perform time-shift maintenance in accordance with recommendations stated in this Manual.
7.
After running-in the tractor, perform
the maintenance works.

Getting tractor moving
ATTENTION! When selecting the re-
quired gear, use the gear shift pattern.
To start the movement, proceed as follows:
• engage the required gear as per the
gear shift pattern;
• step on the clutch pedal;
• in the neutral position shift the gear
shifter lever (1) to the leftmost position and set the range II or I respectively by moving the lever forward or
backward;
• return the lever to the neutral position
and then set the required speed by
moving the lever (1) forward or backward as per the pattern;
Release the parking brake and release smoothly the clutch pedal while
increasing slightly the fuel feed. After
starting the motion, increase the fuel
feed.
Avoid getting moved with a high traction
load (e.g. a plough deepened into the
soil).
ATTENTION! Always step on the
clutch pedal prior to engaging the
range (step) and a gear.
Do not hold the foot on the clutch pedal during operation on the tractor,
since this can lead to clutch slipping,
its overheating and failure.

Stopping tractor
To stop the tractor:
• reduce the engine crankshaft speed;
• use the service brakes to stop the
tractor;
• step on the clutch pedal;
• shift the gear shifter lever to the neutral position;
• engage the parking brake.
Steering
IMPORTANT! The tractors are
equipped with the hydrostatic steering
booster. If the engine is stopped, the
pump does not supply the system and
it starts automatically operating in the
manual mode where turning the tractor
requires a greater force to be applied
to the steering wheel.
IMPORTANT! To stop the tractor in
case of emergency, step on the clutch
pedal and twinned service brakes pedal at the same time.
Shutting down engine
IMPORTANT! Prior to shutting down
the engine, lower the implement onto
the ground and let the engine operate
at 1,000 rpm for 1 to 2 min. This will
decrease the engine temperature.
To shut down the engine, proceed as follows:
• set manual fuel feed lever to minimal
feed position (back to the stop);
• disengage the PTO and shift all distributor levers to their neutral positions;
• lower the implement onto the ground;
• pull engine shut-off lever cord handle to
fully stop the engine;
• turn off the ground switch to avoid storage
battery run-down.

Rear hitch linkage
The three-point rear hitch linkage of category 2 ensures attaching mounted and
semi-mounted agricultural machines and
implements to the tractor with the following connecting pieces:
• length of suspension axis L (distance
between the joints A and C) is 870 mm;
• height of machine post is 510 mm; 610
mm
• diameters of fingers for connection to
the lower rod joints (1) is 28.7 mm;
• diameter of finger for connection to the
upper rod (2) is 25 mm.
В
ATTENTION! Before connecting machines, carefully read this section.
The lower rods consist of two parts:
• the front part or the rod itself;
• the back end with a ball joint. Rated
length of lower rods is 885 mm.
To increase the suspension length, set
the rod ends with the bent front joints
(F70-4605050-01/055-01).
To increase the carrying capacity of the
suspension, replace the rod back ends
(400 mm length) with rod ends with a distance between the joint axle and the front
hole of 320 mm (N50-4605040А2/045А2).
The total length of the lower rod becomes
805 mm.
ATTENTION! With the rod length of 805
mm the carrying capacity of the suspension increases by 10% with a simultaneous decrease of the lift height by 10%.
The same increase in the carrying capacity can be achieved by installing the brace
(1) to additional points (the lift height also
decreases by 10%).
L = 870 mm

rods and the rear joint of the upper rod).
To prevent spontaneous disconnection of
the machine from the tractor, fix the latch of
the automatic coupling with a spring catch
pin.
Limit (telescopic) rods (1)
The rods are used to limit side oscillation of
the suspension lower rods both in the
transportation, and in the working position.
This is especially necessary when working
on slopes, close to ditches, walls etc.
The back end of the rod is connected to
the lower rod, and the front end is connected to the bracket in one of the four
positions depending on the job.
• Position 1. The rods prevent side oscillation of the implement in the transportation position.
• Position 2. The rods prevent side oscillation of the implement both in the transportation and in working positions.
IMPORTANT! Use the positions 3 and 4
only when installing the lower rods to additional suspension axles (upper axles).
• Position 3. The rods prevent side oscillation of the implement in the transportation position.
• Position 4. The rods prevent side oscillation of the implement both in the
transportation and in working positions.
ATTENTION! The rods must be installed only to the bracket holes that
are second from the bottom (position 2)
to prevent damage to the rods.

Control of hydraulic system and
hitch linkage of tractor
On tractors, the hitch linkage is controlled
by the extreme right lever of the distributor.
Working with implements, use only the lift
and floating positions of the lever.
It is forbidden to shift the lever to the
lowering position when working with
soil processing implements!
Use the lowering position only to control
the extension cylinders installed on a machine and intended to control positions of
tools (such as reel, haeder, sharers etc.) of
harvesting, sowing and other machines. If
after completion of a cylinder stroke, the
distributor lever does not return to the neutral position automatically, bring it there
manually. And on the contrary, in case of
an early return of the lever, hold it with
hand to let the operation be completed.
Specifics of operating tractor with
machines requirind drive from rear
PTO
General recommendations:
a) before attaching a machine, make sure
that the PTO control is correctly adjusted;
b) install and secure the required (6-, 8- or
21-spline) PTO shank and engage the
respective speed drive, at that set 540
rpm for the 6-, 8-spline one and 1,000
rpm for the 21-spline one.
To replace the PTO shank, proceed as
follows:
1. Unscrew four bolts and remove the cap (1).
2. Unscrew the four nuts (3) and remove
the casing (2).
55
Page 53
Section E. Unitizing Belarus-510/512 — Operating manual
3. Unscrew the six bolts (4), remove the
lock plate (6) and remove the shank
(5).
4. Install another shank into the spline hole
and install the plate (6), screwing in the
bolts (4) to a torque of 50 Nm.
5. Assemble the other parts in the order
reverse to disassembling.
c) lubricate the shaft and pipe of the tel-
escopic joint of the cardan drive with
solid oil. Install the cardan drive joint
to the PTO shank, secure it in the fix-
ing groove. Make sure that the forks
(1) of the joints of intermediate (tele-
scopic) shaft lay with the ears (2) in
the same plane. Failure to observe
this requirement results in overloads
of the cardan drive and PTO.
d) install the casing of the agricultural
Tractor PTO
end
machine driveshaft;
e) after installing the cardan drive, make
sure, that the elements of the cardan
drive telescopic joint do not stop against
the tractor in the extreme positions of the
110-120 mm
machine; the minimum overlap of the
cardan drive telescopic part must be 110
to 120 mm as in case of a lesser value
the drive may disengage.
f) adjust the safety coupling of the agri-
cultural machine by changing the
length of the spring (1). It must be ad-
justed so that in case of overloads the
cam clutches 2 and 3 rotate each rela-
tive to the other. A too strong tension
of the spring results in maloperation of
the clutch and overloads of the cardan
drive and PTO.
g) engage the PTO independent drive at
minimum engine speed or when the
engine is off. Engage the synchronous
PTO drive when the engine is running
by gradually engaging the clutch.
h) disengage the PTO when making
turns with the machine (for trailer ma-
chines) as well as when lifting the ma-
chine to the transportation position (for
mounted and semi-mounted ma-
chines);
56

Section E. Unitizing Belarus-510/512 — Operating manual
i) after detaching the machine from the
tractor do not leave the cardan drive
joint on the PTO shank;
j) when installing the drive pulley on the
PTO rear cover, as well as drive re-
duction gears of the special machine
drive (cotton-growing, excavating ma-
chines etc.), make sure that they be
centered relative to the shank (fit into
the bore Ø162 mm on the rear cov-
er), and their fastening nuts are tight-
ened up securely.
When working with rotation machines
for tilling:
a) monitor serviceability and normal op-
eration of safety devices;
b) do not engage the PTO with a tool put
down to the ground;
c) bring down the machine with rotating
tools smoothly during tractor movement;
d) do not engage the PTO when the refrac-
tion angle in one of the cardan drive
joints exceeds 22 degrees;
e) when working on hard soils, process
transverse strips to enter the enclo-
sure, only then work the field in the
longitudinal direction.
ATTENTION!
When operating the tractor without use
of the PTO, always shift the PTO control
lever to the PTO ON position, set the
shift clutch of the PTO two-speed drive
to the position 1 (540 rpm), and set the
shifter lever from the independent to the
synchronous PTO drive to the middle
(neutral) position.
When the PTO synchronous drive is engaged, do not drive faster than 8 km/h.
At a speed higher than specified, rotation of the PTO parts exceeds the allowable values, which results in early failures of the unit.
Working with mounted and semimounted machines
piece) is allowed only at a speed not exceeding 15 km/h without driving on public
roads and when performing agricultural
works.
ATTENTION!
Attaching machines such as trailers and
semi-trailers through ТСУ-1Ж (cross-
piece) is strictly forbidden.
When working with single-axle trailers,
install additional counterweights to add
additional load to the tractor front axle.
When a towing gear is installed on the tractor, do not attach semi-trailers (single-axle
trailers) as well as non-standard towbars.
Single-axle machines such as semitrailers are attached to the tractor by
ТСУ-2 (hydraulic hook). Transportation
of the machines using ТСУ-1Ж (cross-

Use of rear attachment with a tow gear
installed on the tractor is strictly forbidden!
The trailers work at speeds determined
by road conditions. With 2ПТС-4-887А
with 20 and 45 m³ bodies, operating at
speeds up to 15 km/h is allowed, as they
have lower stability. Avoid making sharp
turns for such trailers and 1РМГ-4
spreaders to avoid damages to rear
fenders.
The hinge of trailers (2ПТС-4-785А etc.)
must be fixed to prevent its rotation in order to avoid its pinching.
During operation, the fork of the ТСУ-1Ж
haul-and-draw coupler must be fastened
on the trailer cross-member with two
pins. Working with the fork fastened with
one pin is forbidden.
Before work, make sure that the pins and
pivot of the hitch fork are securely splinted. Connect all signaling devices of the
trailers (stop signal, turn indicators, plate
illumination) using the socket installed on
the tractor.
Use of tractor auxiliary equipment
As auxiliary equipment on the tractor, the
drive pulley, additional counterweights to
the front axle, the SA-1 automatic coupler, the spacer for mounting coupled
rear wheels and other equipment can be
installed.
The drive pulley is installed on the cover
of the rear PTO reduction gear and is
driven from the PTO splined shank. To
avoid deformation of the PTO shank,
necessarily install the housing on four
studs with centering the flange in the
PTO cover. Engage and disengage the
pulley using the PTO control lever.
Additional counterweights of a total
weight of 220 kg are installed on a special bracket fastened to the tractor front
bar.

IMPORTANT!
WARNING:
Liquid ballast
Filling tires with liquid ballast is used only in case of weak grip of the wheels to the
ground under unfavorable conditions (such as wetlands etc.).
NOTE: Ballasting the front tires is not recommended as this worsens the tractor
controllability.
During the cold season, it is recommended to apply an aqueous solution of calcium
chloride of the following concentrations:
Ambient temperature, °C Quantity of calcium chloride, g per l of
water
−15°C
up to
−25°C
up to
−35°C
up to
This ensures a low freezing temperature, results in an increase of the solution density
and produces a safe and economical ballast. At correct its use, it won’t damage tires,
tubes or rims.
200
300
435
When a tire is filled with liquid, the tire valve must be in the highest point of the wheel.
The table below specifies volumes of solution filled into the rear tires
Tire size Volume of solution filled in, l per tire
15.5R38 250
Radial tires must no be filled with liquid ballast to more than 40 to 50 per cent of the
volume. If the volume filled in is too large, the remaining air volume won’t be sufficient to absorb
shocks, which may result in tire damage. The reason of it is a lower air pressure for the radial tires. Diagonal tires may be filled up to 75 per cent of their volume.
When mixing a solution, add flakes of calcium chloride to water and stir the solution up
to full dissolving of calcium chloride CaCl2. Never add water to calcium chloride. When preparing
the solution, wear protective goggles. In case of eye contact with the solution, wash the eyes with pure
water immediately for 5 minutes. As soon as possible, call the doctor.

The front wheel track can be adjusted
from 1,350 to 1,850 mm with 100 mm increments in case of symmetrical position
of wheels and 50 in case of asymmetrical
position. To adjust the track, proceed as
follow:
a) put a jack under the front of the
tractor and lift the tractor until the wheels
take off the ground. Put a support under
the tractor front to provide secure and
safe tractor position;
b) loosen the bolts (1), remove the
pins (2) fastening retractable knuckles in
the front axle tube;
c) move first one, then the other retractable knuckle (6). At the same time,
change the length of steering rods by rotating the tube (3) in the tips (5), first unscrewing the locknuts (4) to an extent
corresponding to the wheel track to set.
Fasten the knuckles in the front axle
tube.
d) lower the tractor. Check the wheel

The front wheel track is adjusted stepless by a screw mechanism located on
the front axle sleeves in three ranges:
1,350-1,500 mm, 1,500-1,600 mm,
1,600-1,800 mm.
To obtain the required wheel track, set the
mutual bracing of the whee; rim relative to
the disk as shown on the figure below.
For wheels with constant disk offset, the
track is adjusted stepless within 1,400 to
1,600 mm and 1,750 to 1,950 mm.
To change the track, raise the tractor front
(or front wheels in turn), providing a clearance between the wheels and soil, brake
the rear wheels. Put a support under the
tractor front to provide secure and safe
tractor position, after that;
a) unscrew the bolts (4) and remove the
cover (2);
b) release the wedges of sleeves (3) un-
screwing the nuts by an extent ensuring free movement of conical pair
housings.
Rotating the adjustment screw (1) with
a wrench ensures movement of final
reduction gear housings with wheels
in the front axle sleeves and obtaining
the desired wheel track in the specified ranges. Rotation of the adjustment screw must result in changes of
the steering rod length.

Adjusting front wheel toe-in on tractors with steering booster
Manufacturer sets the front wheel toe-in
withing the range of 0 to 8 mm.
Periodically after each 250 service hours
as well as at each change of front wheel
track check and as necessary adjust the
wheel toe-in. Before checking, adjust
clearances in the wheel bearings and
steering rod joints.
To adjust the wheel toe-in, proceed as
follows:
a) install the tractor on a horizontal hard
surface;
b) set the pitman arm (10) to the middle
position, to do that, turning the steering wheel, set it to a position when the
dipstick in the steering booster housing is buried to a maximum extent;
c) check that the conical pair housings
(for tractors with FDA) or steering
knuckles (for tractors without FDA) be
extended to the length “Б” from the
front axle housing or front axle tube
respectively;
d) adjust the left and right steering rods,
lengthening or shortening them to the
same value, to do that, loosen the
locknuts (3, 5, 6, 8) and by rotating the
left and right tubes (7, 4), set the required length;
e) determine the wheel toe-in by measur-
ing the distance (measurement “Г”)
between the inner flanges of wheel
rims in front (at the wheel center
height) and chalk marks in the measurement points. Then drive the tractor
ahead by a distance, when the marks
be at the rear at the same height and
measure the distance between the
marked points (measurement “В”).
The second measurement must
be greater than the first; the difference between the second “В” and
first “Г” measurements is equal to the
wheel toe-in and must be 0 to 8 mm.
As necessary, adjust the toe-in by
changing the steering rod length. At
that, lengthen or shorten the left and
right rods by the same amount.
f) again check setting of the pitman
arm to the middle position (by dipstick) and the difference between the
measurements “В” and “Г”;
g) lock the steering rod tubes after final
adjustment of wheel toe-in.

After adjustment, install the lock bar 26
and splints 27 (Fig. 2) on the adjusting
screws 21, the rear axle hatch cover,
lock the rod 4 and arm 15 (Fig. 1) as
well as the bolt 9.
During operation, external readjustment
is performed when:
a) PTO slips;
b) the control lever 1 stops against
the cab floor when shifted;
c) the engagement force on the lever
1 exceeds 12 to 15 kgf;
in its extreme positions.
Readjustment is performed as follows:
1. Shift the PTO lever 1 to the PTO ON position;
2. Remove the PTO guard.
3. Unscrew the bolt (16), remove the lock bar
(17) from the eccentric axle shank (15)
and rotate the axle clockwise to select a
clearance between the brake band and
drum (in such a case, the PTO shank
cannot be rotated by hand).
4. Fix the axle with the lock bar (17) and bolt
(16).
5. Install the PTO guard to place.
d) the lever 1 cannot be clearly fixed
Page 68

71
IMPORTANT! In case of significant
wear of brake bands, turn the eccentric
axle by 180°, removing excessive
clearances between the brake band
and drum (flat on the left). After that, fix
the shaft with the lock bar (17) and bolt
(16).
After several external readjustments, the
eccentric axle 15 (Fig. 2) takes the leftmost position (the flat “B” is on the left
vertically), which indicates that no more
reserve of external adjustment is available. In such a case, set the eccentric
axle to initial position by rotating it
counter-clockwise (the flat is on the
right vertically), after that perform adjustments as described for PTO control
adjustment for assembly by manufacturer or PTO repair.
When adjustment is correct, the lever 1
(Fig. 1) in the ON position must be at
least 50 mm away from the cab floor
(dimension “B”).
On tractors of earlier make, the PTO external readjustment mechanism may not
be available (pos. 15, 16, 17, Fig. 2). In
such a case, adjust as specified above
for adjustment of PTO control after repair
or in assembly by manufacturer. On
small-cab tractors, the dimension “B” is
50 to 60 mm. PTO brake efficiency, absence of slipping depends only on the
spring mechanism and first of all on
availability of vacant spaces around it and
the levers connected with it. PTO slipping
means that the spring mechanism or the levers meet additional resistance when moved
over due to lack of lubricant in joints, high
contamination, touching adjacent tractor parts
etc.
ATTENTION!
Perform all adjustments with the engine off.

ADJUSTING FDA CARDAN DRIVE
In the cardan drive, adjust the safety
coupling in the intermediate support and
check the side play in the cardan bearings.
Adjust the safety coupling to transfer of a
torque of 40 to 80 kgf•m (400 to 800 N•m).
Adjust the coupling by tightening the nut 2 of
the rear shaft shank of the intermediate support to ensure transfer of the required torque.
Periodically check the side play in the universal joint cross bearings. If any play is present, disassemble the joint and check condition of the bearings and crosses, replace
worn parts. When assembling the gland
holders, press them in up to stop against the
bearing.
The driveshaft is balanced dynamically. Do
not disassemble the driveshaft without a
special need. When replacing parts such as
pipe with joint forks and flange during operation, balance the driveshaft assembly with
two joints again dynamically by welding
plates to the both ends of the pipe. Unbalance must not exceed 55 g•cm. Do not crank
the driveshafts with tire levers, keys or other
devices to avoid damage to sealings and
failures of cross bearings.

Shift-time maintenance (STM) after each 10 service hours or daily
Operation 1. Oil level in engine crankcase.
Stop the engine, wait for 15 minutes and
check the oil level. The oil level must be
between the upper and lower marks of the
dipstick (3). If necessary, remove the cover
(2) of oil filler neck (1) and add oil to the
upper mark of the dipstick (3)
IMPORTANT! Do not operate the engine
with oil below the lower mark of the oil
dipstick.
IMPORTANT! Do not fill up oil above
the upper dipstick mark. Excessive oil
will burn, giving the fail impression of high
oil consumption for burning.
Operation 2. Coolant level in engine
radiator.
Remove the radiator cap away and check
the cooling fluid level, which shall be below
the upper edge of the filler neck (1) by 5060 mm. If necessary, add coolant to the
level.
IMPORTANT! Do not allow the level to
drop below 100 mm from the filler neck
upper edge.
WARNING! The engine cooling system
operates under pressure maintained by
the valve in the radiator cap. It is dangerous to remove the cap from a hot
engine. Let the engine cool down, put
thick cloth on the cap and turn it slowly
to reduce the pressure before removing
the plug fully. Beware of burns caused
by hot liquid!
