Add or remove shims (9) to obtain 0.1 mm (0.004 in.) end play for the steering knuckle. Tighten steering arm clamping bolt to a torque of 280 N.m (206 ft.-lbs.). TIE ROD AND TOE-IN All Models 3. Disassembly of the tie rod is obvious after an examination of the unit and reference to Fig. 3. Front wheel toe-in should be 2-4 mm (0.080-0.160 in.). To check toe-in, measure the distance between the front wheel rims at the front and at the rear of the wheel rims at hub height. The measurement at Fig. 3—Tie rod used on all two-wheel-drive tractors. 1. Left tie rod end & inner rod 4. Outer tube 2. Clamps 5. Clamp 3. Spring pin 6. Right tie rod end the front must be 2-4 mm (0.080-0.160 in.) less ihan measurement at the rear. To adjust toe-in, loosen clamps (2—Fig. 3) and remove spring pin (3). Loosen clamp (5) and r(»tate outer tube (4) as required. Reinstall spring pin (3 • and tighten clamps. AXLE MAIN MEMBER AND PIVOT PIN All Models 4. REMOVE AND REINSTALL. To remove the axle main member (2—Fig. 2), engage park brake and securely block rear wheels. Remove front weights and bracket, if so equipped. Disconnect steering tube clamp, then disconnect steering tubes from steering cylinder (14). Raise and support front of tractor and place a floor jack under axle main member. Remove steering cylinder and tie rod. Unbolt and remove axle extensions (1 and 12) with steering knuckles, wheel and hub assemblies. Remove protective plug in *Tont of pivot pin (5).

Remove shims (4) from in front and rear of axle main member as pivot pin is rem< »ved. Lower axle main member from tractor. Inspect front and rear pivot bushings (3) and pivot pin (5) for wear and renew as necessary. When rein- stalling, reverse the removal procedures, keeping the following points in mind. Place one 0.5 mm (0.020 in.) thick shim at the rear of the axle and install enough shims at front of axle to obtain the required 0. L-0.3 mm (0.004-0.012 in.) end play Tighten the Allen set screw and locknut (6 and 7) to a torque of 150 N.m (110 ft.-lbs.). 8

SERVICE MANUAL Paragraphs 5-6 FRONT DRIVE AXLE All models are available with a front-wheel drive axle. Front drive axle can be engaged or disengaged with tractor on the go. Front drive axle is spring- clutch engaged and hydraulically disengaged. TVactor must be split between speed transmission and range transmission for access to the front-wheel drive clutch. Front drive axle differential unit is equipped witli a limited slip differential. DRIVE AXLE ASSEMBLY All Models So Equipped 5 REMOVE AND REINSTALL. To remove the frort drive axle assembly (7—Fig. 4), apply park bra]i:e and block rear wheels securely. If so equipped, remove front weights and weight bracket. Loosen front wheel lug nuts. Unbolt and remove front drive shaft and shield as outlined in paragraph 9. Discon- nect steering hoses at cylinder. Cap or plug all open- ings immediately to prevent entrance of dirt into system. Place a fioor jack under front axle and raise front of tractor. Support front of tractor with jack I stands under side rails. Remove front wheel and tire assemblies. Remove locknut (4) and Allen set screw (3). Remove protective plug (1), then using a slide hammer and adapter (CAS-2014), pull pivot pin (2) from axle and front support. Remove shims (5) as pin is removed. Lower axle assembly and remove from under tractor. Bushings (6) can now be removed using a suitable drift punch. Drive new bushings into bore of axle main member until fiush to 1.6 mm (Vi6 in.) below outeir surface. When reassembling, install axle assembly without shims (5). With axle main member pushed rearward against front support, measure distance between front of axle and front support. Subtract 0.1-0.3 mm (0.004-0.012 in.) from this measurement for total shim pack to be installed. Divide this shim pack and install half in front and half at rear of axle main member. Tlie balance of installation is the reverse order of removal, keeping the following points in mind. Tighten the Allen set screw and locknut (3 and 4) to a torque of 150 N.m (110 ft.-lbs.). Tighten wheel lug nuts to a torque of 185-220 N.m (137-162 ft.-lbs.). I Tighten front weight bracket bolts to a torque of 610-730 N.m (450-540 ft.-lbs.). Refer to paragraph 9 for installation of front drive shaft and shield. WHEEL HUB AND PLANETARY All Models So Equipped 6. R&R AND OVERHAUL. To remove either front wheel hub and planetary, loosen wheel lug nuts, then raise and support axle housing. Remove front wheel assembly. Rotate hub until oil plug (25—Fig. 5) is at bottom position. Remove plug and drain oil. Remove two screws (26) and locate the two special wheel studs (with collar). Install two nuts on each stud and lock them together. Unscrew and remove the special studs. Using large screwdrivers or pry bars, separate planetary carrier (20) from wheel hub (3). Remove three screws (29) and lift off cover (28). Number the carrier, planetary gears (16) and shafts (22) for aid in correct reassembly. Drive out roll pins (21) as shown in Fig. 6. Place outer edge of planetary carrier on blocks, then drive out shafts (22—Fig. 5). Remove and discard "O" rings (24). Remove planetary gears (16), washers (15 and 18) and bearing rollers (17). Remove snap ring (14), sun gear (13), spacer (12) and thrust washer (11). Remove the eight cap screws (8) from ring gear carrier (6). Use four of the cap screws as jack screws in threaded holes in ring gear carrier and remove ring gear and carrier assembly. Remove retaining rings (5 and 9), then separ'ate ring gear (10) from carrier (6). Remove outer bearing cone (4), wheel hub (3) and inner bearing cone (2). Remove oil seal (1) from hub, then drive bearing cups (2 and 4) from hub if necessary. I Fig. 4—View of front drive axle assembly removed from tractor. 1. Protective plug 2. Pivot pin 5. Shims 3.
