Remove bolts (1), (2), the washers and the retainers that hold the wheel lean bar to the upper pins of the wheel lean arms. Remove the lock pin or bolt from the wheel lean bar and the front axle. Remove the wheel lean bar from the machine. The weight of the wheel lean bar is 44 Kg (97 lb). 5. Remove four lip seals (3) from the wheel lean bar. Use Tooling (D) in order to remove two bearings (4) from the wheel lean bar. The following steps are for the installation of the wheel lean bar.6.

During installation of the wheel lean bar, check the condition of all lip-type seals used in the wheel lean bar. If any of the seals are worn or damaged, use new parts for replacement. 7. Lower the temperature of two bearings (4). Using Tooling (D) install bearings (4) in the wheel lean bar. Install bearings (4) until each one is 8.0 0.5 mm (.32 .02 in) below face (5).8. Use Tooling (C) in order to install four lip-type seals (3) in the wheel lean bar until they make contact with bearings (4). The sealing lips of lip-type seals (3) must be facing out. 9. Attach lifting slings and a hoist to the wheel lean bar. Position the bar to its original location on the wheel lean arm pins. Install bolts (1) and (2) and washers and retainers that hold the wheel lean bar to the upper pins of the wheel lean arms. Shims must be used between the retainers and pins to maintain an 0.8 mm (.03 in) minimum gap between the retainers and the wheel lean bar. 10. Remove Tooling (B) from both wheel lean arms and the frame.11. Lift the front of the machine enough to get the weight off the axle. Remove Tooling (A) from under the front axle.
