STEERING KNUCKLES 2. The knuckle bushing and or steering knuckle should be renewed when the diametral clearance between the two parts is greater than 0.020. New bronze type bushings are presized and will not require final sizing if they are properly installed. Reconnmended toe-in of front wheels is -i^,;-inch.
AXLE OR AXLE CENTER MEMBER 3. To remove the front axle or axle center member, proceed as follows: Remove tractor hood and grille. Unbolt and remove radiator shell. On models with the fixed tread front axle, also remove the radiator. Raise front of tractor, block-up under front main frame, then remove bolts attaching stay (radius) rods to axle or axle center member. On models with adjustable front axles, unbolt axle extensions from axle main member and swing extensions, steering knuckles and wheels, as units, away from axle center member.

MANUAL STEERING SYSTEM (For Data on Power Steering Refer to Oliver Appendix I For data on power steering refer to page 57. The steering gear, used on the Oliver Super 55 and 550 tractors, is a Saginaw screw and recirculating ball nut type, mounted on top of the tractor center frame cover. The gear unit is provided with three adjustments which control end play of the wormshaft, end play of the lash adjuster screws, and mesh of the sectors. GEAR UNIT ADJUST
•
6. All adjustments with the exception of the end play adjustment of the lash adjuster screws can be made with the gear unit installed on the tractor. End play adjustment of the lash adjuster screws can be made only after removing the sectors from the gear unit.
Before making any adjustments when gear unit is installed on the tractor, disconnect both tie rods (drag links) at the gear sector shaft pitman arms. 6A. WORMSHAFT (SCREW) END
PLAY. Refer to Figs. O654, O655 and O656. To check and adjust wormshaft end play, proceed as follows: Loosen, both right and left side sector lash adjuster screws (37 or 37B), two full turns. Pull up and push down on steering wheel. If this check shows that end play is present, adjust to zero end play by varying the thickness of shims (29) which are located between gear housing (21), and cover and tube assembly (25). Adjustment is correct when the pull, required to keep the steering wheel

It is not necessary to remove the instrument panel to gain access to these shims. All work, necessary either to add or remove shims, can be performed by working through the large holes (H—Fig. O656A) which are located in the battery support. On Diesel engine models, it will be necessary to remove one of the two batteries to uncover the holes in the battery support. Shims are available in thicknesses of 0.002, 0.005, 0.010, and 0.030. 6B. BACKLASH ADJUSTMENT. Before adjusting sector mesh, make sure that wormshaft bearings are correctly adjusted as outlined in preced-
OLIVER ing paragraph 6A. Also, make sure that both steering tie rods (drag links) are disconnected at the sector shaft pitman arms, and that the right and left side lash adjusters (37—Fig. O655 are loosened two full turns. Rotate steering wheel to mid or wheels straight ahead position. Using a screwdriver, rotate the sector adjuster located in side cover (37A— Fig. O656) until all backlash between worm nut and sector is removed. After adjusting the sector which meshes directly with the ball nut, rotate the steering wheel to the mid or wheels straight ahead position. Rotate the opposite sector adjuster screw on right side of gear housing until all backlash between both sectors is re-
moved. All adjustments and checks are made with the steering tie rods (drag links) disconnected. Note: Sector lash adjusters should have from zero to 0.002 end play (controlled with shims) in the "T" slot of the sectors. If this end play exceeds 0.002, it will prevent correct adjustment of sector mesh. Refer to paragraph 8B for method of adjusting the sector lash adjusters. GEAR UNIT R&R
7. To remove steering gear unit from tractor, refer to Figs. O654 and O656 and proceed as follows: Remove the tractor hood and steering wheel. Remove a y4-inch fillister head screw which is located near the upper end of the steering tube (25). Drain engine cooling system. Remove water temperature gauge sending unit from left side of engine cylinder block, and lay sending unit and tube on instrument panel. Disconnect tachourmeter cable
