1. Clean all parts before reassembling.
2. Place the auxiliary brake assembly on a stable plat-
form at or near floor-level with the brake shaft facing
up. Use support blocks as needed to provide stabil-
ity.
3. Place the support end plate over the brake housing.
Position the end plate such that the mounting pad is
to your RH side when looking directly at the brake
release port in the brake housing. Apply Loc-Tite
242 to clean, dry bolt threads and install the bolts
with 110 lb-ft (150 N-m) torque.
4. Lubricate the seal and bearing surfaces on the
brake housing.
5. If necessary, install the bearing into the cable drum
bore, ensuring that it is fully seated against the
shoulder in the bottom of the bore. Apply sealing
compound to the outside diameter of the oil seal.
Turn the spring side of the seal toward the bearing
and press the seal into bore by applying constant,
even pressure. The seal is fully installed when the
outer surface is located flush to the drum face.
6. Turn the drum over and place it onto the brake shaft.
Be careful while lowering the drum into position to
keep from damaging the drum seal.
NOTE:
Due to attempting to align both the drum
bearing and the splines on the brake shaft simulta-
neously, it may be necessary to release the auxiliary
brake to aid assembly. Use the hand pump as
described in the test procedure for the auxiliary
brake to release the brake and allow the brake shaft
to move slightly, aiding drum alignment.
7. Lower the output planet carrier assembly into the
cable drum, making sure the teeth on the planet car-
rier mesh with the teeth in the cable drum.
