27. Set the housing in place and draw it to the sealing
surface with four cap screws (1).
28. With the M12 cap screw in the end of the unloading
shaft, measure the rolling torque of the shaft with the
brake installed. Subtract the smaller value from the
larger value. The resulting differential rolling torque
should be 15-25 N·m (11-18 ft. lbs.).
29. If the differential rolling torque falls out of low range
of 15-25 N·m (11-18 ft. lbs.), the unload clutch brake
(2) will require replacement or addition of shims un-
der the brake.
If the differential rolling torque is out of range high,
shims must be removed from under the brake
washer. Perform the rolling torque measurement
again to verify proper shimming.
To remove the brake washer, lift the clutch housing
from the gearbox. Turn out the four cap screws (1)
securing the brake washer to the housing. Set a new
brake washer in place, and apply locking compound
to the threads of the cap screws. Perform the previ-
ous steps to verify the action of the brake.
Turn out the four attaching cap screws. Tighten the
jacking screws to lift the cover from the gearbox.
