Axle main member and pivot pin



Models With Adjustable Axles


Remove and reinstall
To remove axle main member (13—Figs. 3, 4 and 5), first block rear wheels securely and apply park brake. If so equipped, remove front weights and weight bracket. Unbolt and remove front cover. Support tractor with stands un­der side rails or oil pan, and remove front wheels. Disconnect tie rod ends from left and right steering arms (2 and 6). Unbolt and remove axle extensions (4 and 5) with spindle assemblies. Identify and dis­connect steering cylinder hoses at cylinder. Cap and plug all openings. Remove the cylinder anchor clevis pin. Straighten corners of lock plate (21) and remove cap screws (22), lock plate (21) and cylinder retain­ing bar (20). Hold cylinder upward and slide cylin­der clevis from anchor on axle. Remove steering cyl­inder. Remove center steering arm (19) and tie rods.
Place a floor jack under axle main member (13). Re­move cap screws (16) and thread a slide hammer puller into front end of pivot pin (15). Remove pivot pin, then lower axle main member and remove from under tractor.
Inspect axle pivot bushings (14) and renew if neces­sary, aligning lubrication holes with lubrication fit­tings. Inspect cylinder pivot bushings (18) and steer­ing arm pivot bushings (17) and renew as necessary.
Reinstall by reversing removal procedure, keeping the following points in mind: Tighten cap screws (16) and (22) to a torque of 80-90 ft.-lbs. (110-124 N-m). Bend corners of lock plate (21) against flat of bolt head (22). Tighten nuts on shoulder bolts (12) to a torque of 246-272 ft.-lbs. (334-369 N-m). Tighten tie rod end slotted nuts to a torque of 50 ft.-lbs. (68 N-m).


Models With Nonadjustable Cast Axle


Remove and reinstall
To remove axle main member (16—Fig. 6), block rear wheels secure­ly and apply park brake. If so equipped, remove front weights and weight bracket. Unbolt and remove front cover. Raise front of tractor and support with stands under side rails or oil pan. Remove front wheels. Identify and disconnect steering cylinder hoses at cyl­inder. Cap or plug all openings immediately to prevent dirt from entering system. Place a floor jack un­der axle main member to support axle assembly. Remove clamp bolt (20) and nut, then thread a slide hammer puller into end of pivot pin (19). Remove piv­ot pin, then lower axle main member assembly and remove from under tractor.
Remove tie rod and steering cylinder. Remove spin­dles if desired as outlined. Inspect bushings (17) and renew if necessary. Install new bushings (17) and spacer (18) so that bushings are slightly below flush with outer edges of bore in axle main member.
Reinstall by reversing removal procedure keeping the following points in mind: When installing pivot pin (19), flat for clamping bolts (20) must fact down­ward. Tighten clamping bolt and nut to a torque of 80-90 ft.-lbs. (108-122 N-m). Tighten tie rod end slot­ted nuts to a torque of 50 ft .-lbs. (68 N-m). Lubricate pivot bushings with No. 2 lithium grease.


Tie rods  (Two-Wheel Drive)

Two types of tie rods used with adjustable ax­les are shown in Fig. 1. Two tie rods are used on each tractor. Refer to Fig. 6 for tie rod used on models equipped with the nonadjustable cast axle. Removal and disassembly of tie rods on all models is obvious after examination of unit and reference to Figs. 6 and 1.
Front wheel toe-in on all models equipped with ad­justable axles should be 3/16-5/16 inch (5-8 mm). To adjust toe-in, remove clamp bolt (2—Fig. 1) or set screw (2A) and loosen jam nut (4). Rotate tube (3) to lengthen or shorten tie rod as required. Adjust both tie rods equally. Reassemble tie rods and recheck toe-in. Readjust if necessary.
Front wheel toe-in on all models equipped with the nonadjustable cast axle should be 0-5/32 inch (0-4 mm). To adjust toe-in, refer to Fig. 6 and loosen jam nuts at each end of tube (8). One nut is left hand thread and the other is right hand thread. Rotate tube as required to lengthen or shorten tie rod as­sembly. Tighten jam nuts and recheck toe-in. Read­just if necessary.

To remove the front support (3—Fig. 2 or 3), first block rear wheels securely and apply park brake. Remove hood, grille and side panels. Drain cooling system. Remove radiator as outlined. Remove front axle.
On models with cast front support, disconnect up­per steering lines. Cap or plug all openings. On all models, unbolt and remove oil pan shield. Attach a hoist to front support, then unbolt and remove front support (cast support) or front support and side plate assembly (fabricated support).
Reinstall by reversing removal procedure. Tighten front support mounting 5/8 inch bolts to 220 ft.-lbs. (298 N-m) torque and 3/4 inch bolts to 400 ft.-lbs. (542 N-m) torque.
