Disassembly

Remove the cable drum as described on page 28.

Place the cable drum on a suitable work surface. Inspect the bearings for while still inside the drum. If scoring, heat discoloration or any other damage is present, then replace the bearings.

Remove the drum seals.

NOTE: Remove the seals carefully. With the seals removed, the bearing cones will fall free. Unintentional damage to the bearings can occur if the bearings are not captured or otherwise protected during this process.

If the bearing cups require replacement, remove them using either a multi-jaw puller or by welding pulling lugs directly to the cups. If there is no visible damage to the cups, no replacement is necessary.

Assembly

Place the cable drum on a suitable work surface in an upright position.

If bearing cups were not removed, proceed to the next step. Chill the bearing cups in dry ice to shrink the diameter and aid installation. Install one cup into the drum bearing bore. Use a .002 in. (.05 mm) feeler gauge to make certain the cup is fully seated against the shoulder.

Lubricate the bearing cones with new winch oil. Place one cone in the bearing cup.

Apply non-hardening sealing compound to the outside surface of the seal housing. Properly position the seal in the drum bore. Place a large steel plate over the seal and press or drive into position within the bore.

NOTE: A large plate or mandrel will help to maintain proper alignment and protect the seal from unintentional damage during installation.

Turn the cable drum over and position with the opposite end upright. Repeat the above steps as required to install the bearing and seal for this end.

NOTE: The wire rope anchor pocket is always located on the RH (motor) side of the winch. Lubricate the bearing and seal contact surfaces of the output ring gear and brake housing to aid installation.

Position the cable drum inside the case and support as previously defined.

Install the output ring gear into the LH side of the winch case. Locate the eyebolt as close to top dead center as possible. Ensure the bearing cone is properly positioned on the hub of the ring gear before completing the assembly. Align the mounting holes. Install the fasteners and torque the capscrews to 120 lb·ft (163 N·m).

Refer to the "Winch Assembly Section" of this manual for the remaining steps to complete the winch assembly.
