pinion shaft (13) from rotating.
3. Back off pinion nut (33) approximately 1/8th of a turn
(counterclockwise) and reinsert cotter pin (34).
Overload Clutch Adjustment
1. Suspend the VL2 hoist.
2. Remove wheel cover (38), cotter pin (34), pinion nut (33) and
washer (32).

overload clutch to required setting.
a. Tightening nut (82) will increase clutch overload limit.
b. Loosen nut (82) to decrease clutch overload limit.
Overload clutch should begin to slip with loads shown in
Table 3.
7. When desired clutch overload limit has been achieved bend
one of the outer tabs on washer (81) into a slot in nut (82).
Install washer (32) and pinion nut (33).
