This sendee manual provides specifications in both metric (SI) and U.S. customary systems of measurement. The first specification is given in the measuring system perceived b^ us to be the preferred system when servicing a particular component, while the second specification (given in parenthesis) is the converted measurement. For instance, a specification of "0.28 mm (0.011 inch)" would indicate that we feel the preferred measurement in this instance is the metric (SI) system of measuremtsnt and the IJ.S. customary equivalent of 0.28 mm is 0.011 inch.

DAVID BROWN AXLE

All Models So Equipped

7. TIE RODS AND TOE-IN. Front

wheel toe-in should be 0-1.5 mm

(0-We

inch) measured from wheel rim to wheel rim at front and rear of wheels. Toe-in is adjusted by lengthening or shortening the threaded tie rod ends equally.

Tie rod ends that are excessively worn must be renewed as complete units.

8. R&R AXLE. Front drive axle final

drives and differential may be serviced without removing entire axle and differential housing assembly. However, if housing or trunnion pin are to be serviced, it will be necessary to remove axle housing assembly.

Paragraphs 9-10

To remove assembly, first disconnect

all steering lines and cap openings.

Loosen locknuts (6—Fig. 5) on trunnion

shaft cotter pins (31) until they are

even with threaded ends. Using care to

avoid damaging threads, drive cotter

pins (31) through trunnion shaft. Re-

move locknuts and washers from cotter pins and remove pins (raise right end of axle for more clearance). Support axle and remove core plug (7) from trunnion shaft bore with punch and hammer. Use slide hammer to pull trunnion shaft

(33).

Raise front of tractor enough to clear axle and remove axle. Remove thrust washers (36) and "0" rings (35 and 37).

To reinstall, reverse removal proce-

dure.

Bleed steering system as outlined

in paragraph 58.

9. RENEW TRUNNION SHAFT

BUSHINGS. Remove axle assembly as

outlined in paragraph 8. Remove the four trunnion shaft bushings (34—Fig.

5) using a suitable puller. Install bushings making certain grease hole in each bore is between the two bushings. Refer to Fig. 6 for correct bushing placement.

If trunnion shaft bracket (32—Fig. 5) is to be renewed, remove bracket from axle housing and remove dowel pins. Loosely bolt new bracket to housing and drive dowel pins in. Tighten bolts to 203-244 N-m (150-180 ft.-lbs.) torque.

Lubricate "0** rings and place in thrust washer grooves. When reinstalling thrust washers (36), "0" ring is toward front at front position and toward rear at rear position.

FINAL DRIVE AND STUB

AXLE.

Left and right final drive removal procedure is similar. To remove, raise and support side to be serviced and remove tire and wheel. Rotate hub so drain plug is at bottom and drain

fluid. Remove end plate (12—Fig. 7) and

use pry bars to pull sun gear (15) and shaft (1—Fig. 8) out approximately 5 mm

{%B

inch).

NOTE:

If axle shaft is pulled out too far.

Axle shaft seals can be damaged

Hold axle shaft out and push sun

gear in until split rings (14—Fig. 7) can

be removed. Remove sun gear (15) and thrust washer (16).

NOTE:

Do no push axle shaft into axle

Bend tab washer (2—Fig. 7) away

from locknut (1) and remove nut with

special spanner wrench (CAS-1607). Remove tab washer (2), planetary ring gear (3) and bearing cup assembly (4).

Note number and thickness of shims (5) and remove. Remove spacer (6) and hub (7).

Seal (10) in hub will be tight on axle and should stay on stub axle as hub is removed. Remove bearing (9) and seal (10).

Oil seal wear sleeve (11) should be

renewed if damaged or worn. Use a

Reassemble pin shaft with spacers (22 and 24—Fig. 11) using 1.27 mm (0.050 inch) thick shims (23), but without spacer (26), oil seal (27) and sealing washer (29). Install flange (28), washer (30) and nut (31) on pinion shaft and tighten nut to 190 N m (140 ft-lbs.) torque. Turn shaft in both directions to seat bearings, then mount a dial indicator on carrier so probe contacts end of pinion gear as shown in Fig. 14 and measure shaft end play. Remove pinion shaft and reduce thickness of shims (23—Fig. 11) an amount equal to measured end play. This procedure will provide zero end play and zero preload. However, a tolerance of plus or minus

0.05 mm (0.002 inch) is acceptable.

Reinstall pinion shaft with all spac-

ers and seals. Tighten retaining nut to 190 N-m (140 ft.-lbs.) torque.

until end play of differential in carrier is less than 0.05 mm (0.002 inch) without preloading bearings. Mount dial indicator as shown in Fig. 15, then move carrier assembly sideways as required to obtain correct bevel gear backlash of

0.18-0.23 mm (0.007-0.009 inch) by loosening one adjuster ring one notch at a time and tightening opposite adjuster ring the same amount each time. When bevel gear backlash and differential carrier bearings are properly adjusted, install adjuster ring locks and tighten carrier bearing cap bolts to 163 N-m (120 ft.-lbs.) torque.

MAIN DRIVE SHAFT. Main

drive shaft consists of a sliding yoke, drive shaft tube and two universal joints.

To remove sliding yoke, mark its position for reassembly on correct splines, unscrew threaded cap and slide slip yoke off splines. Use conventional procedure to renew universal joints.

Install drive shaft with slip yoke at differential end and tighten bolts to 54 N-m (40 ft.-lbs.) torque.

R&R TRANSFER GEARBOX.

Drain oil from transfer case and transmission. Capacity is approximately

42 (44 quarts). Remove front drive shaft. Engage front-wheel drive, then remove output shaft flange retaining nut (20— Fig. 16). Remove platform or cab, if equipped, as outlined in paragraph 348 or 349. Remove fuel tanks. Disconnect selector cable from selector shaft (4).

Remove left and right shift lever housings from transmission top cover. Remove bolts from transmission top cov-

er, remove wedge and shims between

top cover and clutch housing, and remove top cover using a suitable hoist. Remove bolt (37) and locknut (39), then slide coupler (38) connecting transfer

gearbox input shaft to transmission

bevel pinion shaft rearward. Remove selector cable bracket (44) and hydraulic pump inlet pipe connector. Support transfer gearbox with a hydraulic jack, then remove gearbox mouting bolts and lower gearbox from transmission housing.

When reinstalling, laminated gasket

Clean and inspect all parts for exces-

sive wear or damage. Lubricate all

parts during reassembly.

21.

Install idler gear (15-Fig. 16) into bottom of transfer gearbox housing (2). Install output gear (17) into housing with hub for sliding gear engagement towards front of housing. Place fixed gear (30) inside sliding gear (29) and install output shaft (19) into rearward side of bottom hole in housing, pushing it through output gear (17) and partially through fixed gear (30). Oil slots on side of fixed gear (30) go against output gear (17). Spacer (31) and bearing (32) must already be assembled on output shaft

(19).

Install six bearing pads in output shaft, concave side against shaft, as it is pushed through output gear (17) and fixed gear (30).

Install rear bearing cup (32), gasket (42), rear cover (43) and cable bracket (44) minus shims (^33). Tighten bolts to 27 N.m (20 ft.-lbs.) torque. Install front bearing (27) and bushing (28) on output shaft and drive front bearing cup (27) into housing (2). Install oil seal (25) in oil seal housing (26) and install oil seal housing on transfer

gearbox housing. Tighten bolts to 27 N-m (20 ft.-lbs.) torque. Hit end of output shaft (19) with a plastic hammer to seat bearings and cups.

Mount dial indicator on transfer gear box housing (2) so probe end contacts end of output shaft (19). Measure and record end play of output shaft. End play tolerance is 0-0.05 mm (0-0.002 inch) for new bearings and 0.05-0.10

mm (0.002-0.004 inch) for used bearings.

To determine proper shim (33—Fig.

16) thickness, subtract 0.025 mm (0.001 inch) from dial indicator measurement if new bearings were installed, or subtract 0.076 mm (0.003 inch) from dial indicator measurement if original bearings are reused. The result is the re-

quired shim thickness to provide rec-

ommended end play.

Remove rear bearing cover (43) and install correct thickness of shims (33). Reinstall cover and tighten bolts to 27

N-m (20 ft.-lbs.) torque. Recheck end play and adjust shim thickness, if necessary, if not withint tolerance.

Tighten bolts to 27 N-m (20 ft.-lbs.) torque and hit idler shaft (34) to seat bearings.

Mount dial indicator so end of probe contacts end of idler shaft (34—Fig. 16). Measure and record amount of end play. End play tolerance is 0-0.05 mm (0-0.002 inch) for new bearings and

0.05-0.10 mm (0.002-0.004 inch) for used bearings.

To determine correct shim (36—Fig.

16) thickness, subtract 0.025 mm (0.001 inch) from dial indicator measurement if new bearings are used, or subtract

0.076 mm (0.003 inch) from dial indicator measurement if original bearings are reused. The result is the required thickness of shims needed to obtain desired end play.

Remove rear end plate (46—Fig. 16) and install correct shim (36) thickness. Reinstall end plate (46) and tighten bolts to 27 N-m (20 ft.-lbs.) torque. Recheck end play and adjust shim thickness, if necessary, if not within required tolerance.

23.

Install input shaft (12—Fig. 16)

and bearing assembly through front of

housing (2) and input gear (13). Install bearing cup (14) and end plate (3). Tighten bolts to 27 N-m (10 ft.-lbs.) torque. Drive rear bearing (11) onto input shaft (12) until seated. Install bearing cup (11) and end plate (46). Tighten bolts to 27 N-m (20 ft.-lbs.) torque. Set end play in the same manner as outlined in paragraph 22.

(16—Fig. 25). Use a soft hammer to drive pinion shaft out of bearings and carrier. Remove bearings, shims and bushing from pinion shaft and carrier as necessary.

Mark end plate (37), bevel ring gear (3) and cage (4) so they can be reassembled in their original positions. Remove

carrier bearings (6 and 36) as neces-

sary. Separate end plate from cage and remove side gear (20) and friction plates.

To remove cross-shaft retaining pins (25 or 30), remove the cage stud (38) that is aligned with one of the pins.

The remaining two pins are aligned with end plate locating dowels (33). Use

a punch to drive the two retaining pins and dowel pins out of cage. Drive long

cross-shaft (21) out of cage, then re-

move the two pinion gears (22 and 28) and thrust washers. Drive short crossshafts (24 and 31) out of cage, then remove cross-shaft block (26) and remaining two pinion gears and thrust washers. Remove side gear (27) and friction plates. Remove bevel ring gear

(3) as necessary.

Bevel ring gear and pinion shaft are

serviced as a matched set only. If bevel ring gear and pinion shaft, pinion shaft bearings or carrier are renewed, pinion shaft protrusion must be set as outlined in paragraph 35.

Reassemble by reversing the disassembly procedure while noting the foliowing special instructions: Be sure

tabs of friction plates (9 and 34—Fig.

25) engage the grooves in differential cage (4) and end plate (37). Tighten end plate nuts to

48 N • m

(35 ft-lbs.) torque.

When renewing carrier bearings (6 and

36),

heat bearings to 120°C (250°F) maximum before installing. Heat ring gear before installing on differential cage.

Tighten retaining bolts to 90 N-m

(65 ft.-lbs.) torque.

Check and set friction plate end play as outlined in paragraph 34. Set pinion shaft protrusion as outlined in para-

graph 35. Adjust differential carrier

bearings and bevel gear backlash as outlined in paragraph 36.

DIFFERENTIAL FRICTION

PLATE END PLAY. To check end

play of friction plates, mount a dial indicator so probe extends through axle shaft opening and contacts end of one of the side gears. Insert a screwdriver or other suitable tool through opening in side of differential cage, pry side gear upward and measure end play.

Correct end play is 0.03-0.20 mm (0.001-0.008 inch). End play can be adjusted by replacing 2.8 mm spacer with a 2.9 mm spacer (1 and 40—Fig. 25).

Renew friction plates if end play is still

excessive.

PINION SHAFT PROTRU-

SION AND BEARING PRELOAD.

To set pinion shaft protrusion, install bearing cups and cones in carrier housing. Use a bolt, washers and nut as shown in Fig. 27 to hold bearing cones in place. Tighten bolt and nut until bearing cones are difficult to turn.

Install carrier bearing caps (1—Fig.

27) on carrier housing and tighten nuts to 205 N-m (150 ft.-lbs.) torque. Measure and record diameter of bearing bore (A).

Place a shaft (3), having a diameter of at least 25 mm (1 inch) and having a cross hole drilled through it, across bearing bores as shown in Fig. 27. Measure and record diameter (B) of shaft. Using a depth gage measure from top of shaft to face of inner bearing cone (Fig. 28) and record measurement (C-Fig. 27).

To determine correct thickness of

shims (11—Fig. 25) required to obtain desired shaft protrusion, use the following calculations: Subtract diameter of shaft (B—Fig. 27) from depth gage measurement (C). Add this figure to one-half the diameter of carrier bearing bore (A). The result is dimension (E).

Then subtract dimension etched on pinion shaft gear face (dimension is in millimeters) from dimension (E). The resulting dimension will be correct shim (11—Fig. 25) thickness to install to properly set pinion shaft protrusion.

Install correct thickness shim

(11 — Fig. 25) on pinion shaft with chamfered side towards gear end of shaft. Press inner bearing onto shaft until seated

against shim.

DIFFERENTIAL CARRIER BEARINGS AND BEVEL GEAR BACKLASH. Pinion shaft protrusion

and bearing preload must be properly set before adjusting differential carrier bearings. Install differential unit in carrier housing making certain ring gear is aligned with drain hole in carrier as shown in Fig. 29. Install bearing support caps, but do not tighten retaining nuts securely at this time. Install bearing adjuster rings and turn adjuster ring on ring gear side of differential

until ring gear contacts pinion gear.

Then turn adjuster ring on side oppo-

site ring gear until all bearing end clearance is removed, but do not preload bearings. Mount dial indicator as shown in Fig. 30, then hold pinion shaft and move ring gear to check backlash. Turn adjuster rings as needed to move ring gear sideways to obtain recommended backlash of 0.15-0.25 mm (0.006-0.010 inch). Loosen adjuster ring one notch at a time and tighten opposite adjuster ring the same amount when setting backlash.

PINION SHAFT PROTRU-

SION AND BEARING PRELOAD.

To set pinion shaft protrusion, install bearing cups in carrier housing. Install carrier bearing caps (9—Fig. 35) and tighten nuts to 198 N-m (145 ft.-lbs.) torque. Install bearing cones in carrier using a bolt, flat washers and nut (Fig.

38) to hold bearings in place. Tighten nut and bolt until bearing cones are difficult to turn.

Measure and record diameter of car-

rier bearing cap bore (A—Fig. 38). Place a si ift (3), having a diameter of at least 2J mm (1 inch) and having a cross hole drilled through it, across bearing bores as shown. Measure and record diameter (B) of shaft. Insert a depth gage through hole in shaft and measure distance (C) from top of shaft to face of inner bearing cone.

To determine correct thickness of shims (10—Fig. 35) required to provide desired pinion shaft protrusion, use the

SHOP MANUAL

www.maskinisten.net

ign Ring

With Drain

following calculations: Subtract diameter of shaft (B—Fig. 38) from depth gage measurement (C). Add this figure to one-half the diameter of carrier bearing bore (A). The result is dimension (E). Then subtract dimension etcned on gear end of pinion shaft (dimension is in millimeters) from dimension (E). The resulting dimension will be correct shim (10—Fig. 35) thickness to install to properly set pinion shaft protrusion.

Install correct thickness shim (10) on pinion shaft with chamfered side towards gear end of shaft. Press inner bearing cone onto shaft until seated against shim.

To set pinion shaft bearing preload, assemble pinion shaft in carrier minus seal (16) and seal carrier (17). Install spacer (12) and a shim 0.5 mm (0.020 inch) thicker than original shim removed during disassembly. Install out-

er bearing cone and the old locknut (15).

POWER STEERING

Hydrostatic power steering is option-

al on Model 1190 and standard on all other models. Hydrostatic steering systems are comprised of a pump, steering

(control) valve and steering cylinder. Tractors are steered hydraulically with

no mechanical link between steering

wheel and front axle.

Power steering pump for 1190 and 1194 models is a 16 L/min. (4.2 gpm) Hobourn-Eaton pump having a remote reservoir containing filter and breather assemblies. All other models use a 10.5 L/min. (2.8 gpm) Sundstrand pump utilizing differently arranged remote filter, breather and reservoir systems or a reservoir as an integral part of the pump.

All models use an Orbitrol ()SP-100 or OSP-125 steering valve. Service procedures are similar for either valve.

FILTER

All Models

56.

The steering hydraulic system on models equipped with standard steering cylinders is basically self-bleeding. To purge trapped air from the system, first be sure reservoir is filled to proper level. With engine running, turn steering wheel from lock to lock several times until steering operation is satisfactory. Check reservoir for correct oil level again and fill if necessary.

SYSTEM OPERATiNG PRESSURE

Aii Modeis

60,

A pressure test of power steering circuit will disclose whether pump, relief valve or some other unit in system is malfunctioning. To check pressure, disconnect pump outlet line and install a 0-20000 kPa (0-3000 psi) pressure gage into pump outlet port.

NOTE: note pressure gage reading. Pump is operating at maximum pressure during test and

fluid overheating and pump damage may

result if engine is operated for a iong od of time.

Run engine oniy iong enough to

peri-

Start and run engine at 1500 rpm only long enough to read pressure gage. Pump pressure for 1190 and 1194 models should be 7930 kPa (1150 psi). Pressure for all other models should be 10340 kPa (1500 psi). If pump fails to reach specified pressure, remove and examine pump.

Inspect all parts for excessive wear and damage. An "0** ring and seal kit, front bearing and pumping element and shaft assembly are available for service.

To reassemble, install drive key (16) and carrier (15) on shaft. Position manifold plate on the cover with timing grooves (Fig. 47) facing up. Assemble shaft into bore of manifold plate. Install cam ring (Fig. 48) with cam mark towards drive end of shaft as shown, then install rollers in carrier. Position alignment pin in smallest hole in cam ring. Install end plate (9—Fig. 46) and the two retaining screws, but do not tighten screws.

It is recommended that an alignment tool be made from an old pump body by drilling two holes through end of the body to align with end plate screws. Install tool over pumping element to align components. Check for free rotation of shaft, then securely tighten the two screws through the holes of the tool. Remove the tool.

Install new "0" rings and shaft oil seal and lubricate with clean oil before reassembling. Protect lip of seal, then install body (6—Fig. 46) over pump assembly. Install cover retaining ring (22).
