noting the direction of lockup on the clutch. The clutch
assembly must be assembled with the arrow pointing in
the proper direction for the winch to operate properly.
Inspect the area on the driver where the clutch runs. If
there is any pitting or spalling on the driver, it and the
clutch must be replaced.
Assembly
1. Assemble the driver and clutch assembly. Make sure
that the clutch is installed correctly.
2. Install a new seal (4, Figure 11-33) into the brake
housing, temporarily install the input sun gear, and slide
the driver/clutch assembly onto the sun gear spline.
Install the spacer 5 into the housing.
3. Install the stator plates and the friction discs into the
housing starting with a stator plate (Figure 11-43) and
followed by a friction disc (Figure 11-44). Alternate stator
plates and friction discs until all are installed. There is
one more stator plate than friction discs, so you will

measurement is less than shown, too many plates or discs
have been inserted or they are not seated properly.
