The Service Manual for the Valmet tractors is intended to be a practical reference source to be used in workshop. The repair instructions in the manual are based on methods which have been worked out in practice
during normal workshop conditions and which are based on the use of special tools from the manufacturer
when stated in the instructions. The manual also contains descriptions of the design and function of the
components.
Detailed maintenance instructions can be found in Operator’s Manual.
The Service Manual will be continually updated with new revised pages which should be inserted in the
manual. Alterations and additions will first appear as service bulletins.
Only genuine Valmet spare parts should be used to ensure the best possible function of the machine. Certain operations should be carried out with the aid of special tools designed by Valmet.

General instructions for repairs
Outer oil seals
The Service Manual contains instructions for changing all outer oil seals, (e.g. oil seals on the PTO shaft end, on the output shaft
to the front wheel drive and on the pinion shaft on the powered front axle, and so on).
Sealing compound and glue
If sealing compounds or glue are required for the repair work, the instructions will specify a sealing compound or glue which is
readily available through specialist dealers. Some seals should be greased before fitting and the space between the lips of the
seal should be filled with universal grease. If the seal is to be pushed over splines or sharp edges the seal should be protected
with for example a thin plastic foil.
Tightening torques and setting values
All necessary tightening torques and setting values for each repair operation are given at the beginning of each repair section
under the heading Technical Data. The most important values can also be found in the repair instructions.
Table 1 later gives the tightening torques in order of dimension, quality and surface treatment. The values given in the table should
be used if the tightening torque is not given in the repair instructions.
Safety
Always bear safety in mind when repairing or servicing the tractor. Use tools and lifting devices in the correct way . When you
are removing tractor components or splitting the tractor,every tractor part must be supported in such a way, that no risk of accident
exists. Avoid working under the supported tractor part if it is not absolutely necessary. When supporting the tractor the centre of
gravity of the frame part must always be checked. For instance the wedges must always be fitted between front axle and engine
to prevent axle oscillation when splitting the front frame of the tractor.
Trouble ---shooting
The following procedure, combined with the information contained in the workshop manual will be helpful in tracing faults accurately. It consists of following a number of logical steps to locate and correct the problem:
a) Determine the problem
b) List possible causes
c) Differentiate the causes
d) Conduct checks in logical order to determine the exact cause
e) Consider approximate remaining service life against cost of parts and labour..
f) Make any necessary repairs.
g) Recheck the parts and functions for correct operation

Handling of heavy components
Unless otherwise specified, all removals should be accomplished using adjustable lifting equipment. All supporting
slings must be parallel to each other and as near vertical as
possible in relation to the object being lifted. However, where
slings are of a far greater capacity than the weight of the load
to be fitted, a triangular lifting arrangement may be used.

Cleanliness
To ensure long life of a machine, it is important to keep dirt and
foreign material out of its vital working components. Precautions must be taken to safeguard against this. Enclosed compartments, seals and filters have been provided to keep the
supply of air, fuel and lubricant clean. These protective devices must not be removed.
Whenever hydraulic, fuel, lubricating oil or lines are disconnected, clean the point of disconnection and the surrounding
area. As soon as a line has been disconnected, cap, plug or
tape the line or opening to prevent the ingress of foreign material.
The same cleaning and covering precautionsshould be taken
when access covers or inspection plates are removed.
Clean and inspect all parts. Make sure that all passages and
holes are clear. Cover all parts to keep them clean. Make sure
parts are clean when they are reassembled. Leave new parts
in their wrapping until they are actually needed for reassembly
Assembly
When reassembling a machine, complete each step in sequence. never partially assemble one part then start to assemble another. Make all recommended adjustments. Al ways check the job on completion to ensure that nothing has
been overlooked. Recheck the various adjustments before
putting the machine back into service.

When necessary the forged eyebolt can be supported in the
way shown in figure above. Sleeve D may or may not be
welded to plate.
Warning! If a part resists removal, check that all nuts and bolts
have been removed and that there is no interference from adjacent parts.
Note! Before fitting new parts, remove rust preventative compound from all machined surfaces (usually ”peel --- off substances).
Lubrication
Where applicable, fill the compartments of repaired or renewed components with the quantity, type and grade of clean
lubricant recommended in the routine maintenance section of
the Operator’s Manual.
Shims
When shims are removed, tie them together and identify their
location. Keep shims clean and take care not to bend them
before refitting them.
Gaskets
Make sure that the holes in gaskets line up with lubricating oil
passages in the mating parts. If gaskets have to be made, use
material of the correct type and thickness. Make sure that
holes are punched in the right places.
Incorrectly punched gaskets can cause serious damage.
Lip type rubber seals
Lubricate the lips of lip---type rubber seals with oil before fitment. Do not use grease on seals, except for grease seals.

used to identify the sides of a single element seal. With a few
exceptions, the toe of a single - --lip is located on the lubricant
side. Some seals have a second auxiliary lip which has no
spring.
Cables and wires
When removing or disconnecting a group of cables or wires,
label each one to ensure correct refitment.
Locking devices
Correct and incorrect method of fitting and bending locking
tabs.
Slackening of nuts and bolts is prevented by mechanical
means such as lockwashers, tab washers and cotter pins, or
by Loctite--- type locking agents.
Flat retainers must be installed properly to be effective. Bend
one end of the retainer against the edge of the part. Bend the
other end against one of the nut or bolt head.Always fit new
retainers in compartments which house moving parts. When
fitting lockwashers on aluminium housings, place a flat
washer between the lockwasher and the housing.
Note!
1) Never fit a lockwasher (Grower, fan, spring, etc.)under a nut
or bolt to which a specified torque has to be applied.
2) Always thoroughly degrease components before applying
Loctitetypelockingagents.
Bushes and press fits
Do not fit bushes with a hammer alone. Use a suitable fitting
tool and a hammer or, better still, a press if possible..
Correct and incorrect use of retainers
When using a press, ensure that pressure is applied directly
in line with the bore. If the ring has an oil hole, take care to align
it with the oil hole in the mating part. When press fitting a part
into another part, lubricate the mating surfaces. Tapered parts
should be assembled dry. Before assembly, check that the
tapers are dry and free from burrs.
Fitting bolts in blind holes
Use bolts of the correct length. A bolt which is too long may
”bottom” before the head comes into contact with the part it
is to hold: this will cause damage to the threads. If a bolt is too
short, there may not be enough threads engaged to hold the
part securely.

General
Correct maintenance at the right time is a basic condition for
reliable operation of the tractor. Maintenance costs are small
compared with any repair costs resulting from lack of maintenance. The most important measures are those which you
carry out yourself and which include lubrication and various
checks and adjustments.
The service intervals shown apply for normal operating conditions but in more severe conditions servicing should be carried out more frequently.
Generalinstructionsconcerningoil
checks and oil filling
---Alwaysstoptheenginebeforestartingwork
---Apply the parking brake to ensure the tractor cannot
move. If the ground is uneven the wheels should be
scotched
---W ash down the tractor first so that the work can be done
more easily and quickly.
---Always observe the utmost cleanliness in all maintenance work. Thoroughly wipe off filler caps and plugs as well
as surrounding parts of the tractor before filling up with fuel
or oil.
---Inspect the oil and filters when changing. Large
amounts of dirt (e.g. heavily clogged filters) can point to a
fault which could cause extensive and costly repairs if not
corrected in time.
---When carrying out checks the tractor should stand on level
ground.
---Levels should be checked in the morning when the oil
is cold and has had time to run down to the bottom of the unit
concerned.
---When changing the oil, bear in mind that the oil can be
very hot when it drains from the tractor. Waste oil and oil
filtersshouldbehandledcarefullyanddisposedofproperly
---After completion of the service work always replace all
safety covers etc.
---Always clean the grease nipples before applying the
grease gun.
---Apply grease through the nipples until clean grease
oozes out (unless otherwise instructed).
---Wipe away superfluous grease which has been
pressed out at the lubricating point.
---Preferably carry out lubrication with bearing points and
joints unloaded and with the bearings in different positions.
Lubrication and maintenance schedule
All intervals are counted from zero hours on the hour recorder.
For example, 1000 hours service is carried out every 1000
(yearly), 2000 hours (every other year) etc. even if the guarantee service has been carried out.
Example: The 1000 hour service contains all items mentioned
under 10 h/Daily, 50 h/once a week, 250 h, 500 h and 1000 h.
