Torque Limiting Clutch Adjustment
NOTE: The large adjusting nut on the side of the clutch
assembly is a standard type thread.
If the torque (slip) setting of the clutch assembly is
off spec 220 ft. lb., the large adjusting nut must be
(tightened) turned clockwise to increase the torque
setting or (loosened) counter-clockwise to decrease
the torque setting.
1. Bend lock tabs away from the adjusting nut.
2. Hold the drive axle steady using service tool (P/N-
0080229) and the torque wrench used to check the
torque setting.
3. Depending on how far off the original torque setting
was (see note at beginning of this procedure),
tighten or loosen the adjusting nut accordingly, then
recheck the (slip) torque setting. Repeat this until
the proper (slip) torque setting is achieved.
4. When proper torque setting is achieved, bend three
(3) of the lock washer - lock tabs down against the
adjust nut.
5. Re-install the drive wheels per instructions Section
3.3, Drive And Caster Wheels.
