Winch Assembly - BRADEN PD12C Series Installation Maintenance And Service Manual

NOTE: PD15B winches ONLY
The drum closure will not fit through the opening in the base. For winches with a three piece base, first assemble the
bearing support side plate (91) to the base plate (90). Go to step 1 and follow the assembly procedure. Install the
motor end side plate and tie bar(s) after installing the drum closure in step 10.
For winches with a one piece cast base, use the following assembly procedure. With the drum horizontal, install the
output planet carrier assembly, output sun gear (34), thrust washer (43), primary planet carrier assembly, thrust washer
(31) and drum closure. (Apply a light coat of grease to the thrust washer to hold them in position.) Position the drum
in the base and install the bearing support. (Refer to step 3 for two caution statements.) You may have to rotate the
bearing support or planet gears to engage the bearing support with the output planet carrier. Install and hand tighten
the bearing support capscrews. Stand winch on bearing support end and visually check to verify the primary thrust
plate is properly positioned. (Refer to caution and drawings in step 16.) Install the primary sun gear and proceed to
step 11 to complete winch assembly. Tighten bearing support capscrews to recommended torque after motor is
installed.
CAUTION
Winches with a three piece fabricated base use
special shoulder capscrews to fasten side plates to
the base plate. DO NOT use standard capscrews in
their place.
1. Place winch base on side with bearing support end
up.
2. Install a new bearing in the drum if replacement is
necessary. Apply a non-hardening sealant on the
outside diameter of the new seal. Install the spring
side of the seal next to the bearing, then press into
the drum, using a flat plate to avoid distortion. Be
sure drain plug is installed securely.

WINCH ASSEMBLY

Make certain the snap ring is installed on the bearing
support. This snap ring will keep the output planet
carrier correctly positioned in the winch. Gear train
damage may occur if this snap ring is omitted.
3. Center the drum in the opening of the base.

Lubricate the bearing support with petroleum jelly
