OSCILLATION BEARING CLEARANCE
NOTE
During assembly, it is recommended that this clearance measurement be made prior to installing drum into
yoke.
1.
Put roller on a hard level surface. Stop engine and apply parking brake (TM 5-3895-379-10).
2.
Attach base of dial indicator to steering pivot bearing plate. Set dial indicator actuator against front face of yoke center
plate.
WARNING
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.
3.
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.
4.
With dial indicator actuator set against front face of yoke, set dial indicator to zero.
5.
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 and record reading.
NOTE
When removing or adding shims behind plate, remove or add equal amounts at top and bottom of plate.
6.
Total movement should be .002 - .010 in (.05 - .25 mm) on a new assembly. The maximum reading for used assembly
should be .020 in (.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.
NOTE
Inadequate bearing lubrication may result if zero end play or a preload condition is present.
7.
If proper clearance cannot be obtained with removal
or addition of shims, oscillation assembly should be
DIAL
disassembled. Bushings and any other worn or dam-
INDICATOR
aged components should be replaced.
