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 rubbing against drum flanges.

2. Place air shifter assembly #1 over shifter shaft aligning clevis over flats of shaft. Secure clevis to shaft using clevis pin

#62 and cotter pin #61. 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 #39 (flanged hx. hd. serrated). Tighten securely, but do not torque.

3. Hook up air (70 to 90 psi) to inlet port of air cylin-

der 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 #39 should be loos-
ened and the plate pulled away from the drum
approximately .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 #39 to 18 ft. lbs. each.
Attach cover #43 using (4) capscrews #52.
