Set the shifter so that the screw heads in yoke engage the external groove in the locking ring. Push the clutch housing onto the drum shaft with the shifter shaft sticking out through the slot in the top of the clutch housing. Attach shifter yoke to the clutch housing using (2) shifter yoke mounting screws.
3. 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.
4. Place 299710 air shifter assembly over shifter shaft aligning clevis over flats of shaft. Secure clevis to shaft using 424029 clevis pin and 424005 cotter pin. 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) 414126 capscrews (5/16-18 x 3/4 flanged hex head serrated). Tighten securely, but do not torque.
5. 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) 414126 capscrews should be loosened 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) 414126 capscrews to 18 ft. lbs. each. Attach shifter cover to shifter bracket assembly using (4) 416214 #10-32 x 1/4" round slot head screws.
