Assembly
Thoroughly clean and carefully inspect all components prior to assembly. If a component's condition is questionable-replace it!Due to machining tolerances, installation of any new components listed below will alter the original shim pack used between the bevel gears to establish the required backlash between the bevel gears and bevel pinion.Measurements of components must be taken and used to establish a new shim pack thickness to maintain the required .004-.012 (.1-.31 mm) backlash)Use the following formula and list of components to be measured to establish the new shim pack. Due to machine tolerances, the thickness of the shim pack must be determined individually for each winch. The same parts which have been used for measuring must be used together. Shim Pack Thickness:Z = B1 + B2 + M1 + M2-S1-S2-S3-S4-R1-R2-R3-R4The basic shim pack supplied through Service Parts is .120 in. (3.05 mm) thick. Record dimensions M1 and M2, bevel gear mounting distance. The mounting distance has been etched into the inside surface of the bevel gears. Measure and record dimension B1 and B2, thrust bearing assembly. Each thrust bearing assembly includes: one thrust bearing (7) and two thrust bearing races (13). Measure and record dimension S1 and S2, thrust bearing, spacer thickness (25) and S3 and S4 bevel gear spacer thickness (30). Measure and record dimension R1,R2, R3 and R4 bevel gear bearing inner race (6) thickness.The shim pack thickness, (Z) to use in re-assembly of
