OSCILLATION BEARING CLEARANCE - Continued
Ensure pry bar is in good condition and suitable for task. Keep hands clear of heavy parts
supported and use caution while working with pry bar to avoid injury.
Insert a long, heavy pry bar between yoke assembly and steering pivot housing. Push hard on pry bar to move
drum and yoke assembly as far forward as possible.
With dial indicator (Figure 14, Item 1) actuator set against front face of yoke, set dial indicator to zero.
Insert a long, heavy pry bar between yoke assembly and plate. Push hard on pry bar to move drum and yoke
assembly back toward rear frame. Observe dial indicator (Figure 14, Item 1) and record reading.
When removing or adding shims behind plate, remove or add equal amounts at top and
bottom of plate.
Total movement should be 0.002 - 0.010 in. (0.05 - 0.25 mm) on a new assembly. The maximum reading for
used assembly should be 0.020 in. (0.51 mm). If movement is too great, clearance can be reduced by removing
shims from behind plate. If clearance is not enough, add shims to increase clearance.
Inadequate bearing lubrication may result if zero end play or a preload condition is present.
If proper clearance cannot be obtained with removal or addition of shims, oscillation assembly should be
disassembled. Bushings and any other worn or damaged components should be replaced.
