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 393 Nm (290 ft-lb)
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
#90 and cotter pin #89. 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 #82
(flanged hx. hd. serrated). Tighten
securely, but do not torque.
3. Hook up air 4,8-6,2 bar (70-90 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 2,3 mm (.09 in) (max.)
between the locking ring and retainer
plate when the winch is fully disengaged.
If there is contact, the (4) capscrews #82
should be loosened and the plate pulled
away from the drum approximately 1,5
mm (.06 in). 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 #82 to 24 Nm (18 ft
-lb) each. Attach cover #81 using (4)
capscrews #84.
