ADJUSTMENT OF CLUTCH AIR SHIFTER
1. Place winch assembly back into mounting frame and
reattach using (8) mounting bolts and lockwashers.
Torque mounting hardware to 290 ft. lbs. each. Make
sure that gear housing and clutch housing are not rub-
bing against drum flanges.
2. Place air shifter assembly #5 over shifter shaft aligning
clevis over flats of shaft. Secure clevis to shaft using
clevis pin #76 and cotter pin #75. Place shifter shaft in
the "ENGAGED" position. With the air cylinder shaft fully
retracted, push shifter assembly toward the drum until
all play is taken out of the shifter shaft. Secure shifter
assembly to clutch housing using (4) capscrews #46
(flanged hx. hd. serrated). Tighten securely, but do not
torque.
3. Hook up air (70 to 90 psi) to inlet port of air cylinder and
disengage clutch. Look into the opening in the clutch
housing and verify that the locking ring and retainer plate
are not making contact. Locking ring and retainer plate
must not make contact. There must be a clearance
(gap) of .09 inch (max.) between the locking ring and
retainer plate when the winch is fully disengaged. If
there is contact, the (4) capscrews #46 should be loos-
ened and the plate pulled away from the drum approxi-
mately .06 inch. Tighten screws securely and check
action to assure needed clearance. Repeat adjustment
procedure as needed to acquire needed gap. Shift
clutch 2 or 3 times to verify proper shifting of clutch.
After final adjustment, torque (4) capscrews #46 to 18
ft. lbs. each. Attach cover #43 using (4) capscrews
#61.
