housing (44) with a capscrew (28) and lockwasher (29). Tighten the capscrew to 21-24 ft-lb. torque.
Be sure to lubricate the main bearings through the housing fitting near the shaft exit.
k. Install the lubrication fitting (38) in the rear (output) end of the clutch shaft (if used).
l.
Set the clutch hub and back plate assembly on the bench with the hub section facing up.

0.31 inch. This is necessary to prevent operating interference.
q. Install the eight spring bolts (10) and pressure springs (9) through the floating plate and into the hub
and back plate. Tighten the spring bolts until their shoulders contact the hub and back plate; then,
tighten them to 160-175 ft-lb. torque.
r. Assemble the collar (19) halves and shims (20) to the sliding sleeve (17) with the two capscrews (22)
and two hex-nuts (18). Tighten the hex-nuts to 38-42 ft-lb. torque. Install the two guide pins (6) with
flats into the sliding sleeve (17) if they were removed during disassembly.
s. Install the sliding sleeve (17) with attached parts entering the guide pins (6) into the hub of the hub
and back plate.
CAUTION
When the cotter pins are spread, the radius of the pin
ends must not be greater than 0.31 inch. This is
necessary to prevent operating interference.
t. Attach the loose ends of the eight links (16) to the sliding sleeve (17) with four pins (13) and four
cotter pins (15). Spread the cotter pins.
u. Install the hose fitting (23) into the collar (19) and attach the flexible hose to the fitting.
