1. Remove the four capscrews securing the brake
valve to the motor. Remove the four cap-
screws securing the manifold block to the motor.
Disconnect the motor case drain hose at the motor.
NOTE:
Some installations have the brake release
hose connected directly to the motor, instead of
to the manifold block. In this case, disconnect the
brake release hose at the motor port. Stand winch
up on drum support with the motor end up and
secure in this position.
2. Before removing the motor, it is a good idea to note
or mark the position of the motor in relation to the
winch, since it will be rotated 180° when reinstalled.
Remove the capscrews securing the motor to the
winch and carefully remove the motor.
3. Remove the brake clutch assembly from the motor
support. Turn the clutch over and re-install it into
the center of the brake pack. Be sure the inner race
engages the input planet gear shaft.
4. Install a new O-ring on the motor pilot. Rotate the
motor 180° from its original position and install it
onto the winch. Install and tighten motor capscrews
to recommended torque.
5. Install new O-rings in the brake valve and manifold
block. Attach the brake valve and manifold block to
the motor using the original capscrews and tighten
to recommended torque.
6. Connect the motor case drain hose to the motor
case drain port.
7. If your winch had the brake release hose connected
directly to the motor, the original motor port must be
plugged and the hose connected to the motor pres-
sure port near the manifold block (lowering port).
8. Operate the winch slowly in both directions and
check for oil leaks and/or unusual sounds from the
winch. The winch should operate smoothly in both
directions. Refer to “WIRE AND BRAIDED ROPE
INSTALLATION” and properly install rope onto the
winch drum.
REVERSING DIRECTION OF DRUM ROTATION
(020, 029, 034, 039 motors ONLY)
To change the direction of rotation, two things must be changed on the winch. First, the motor must be made to
rotate in the opposite direction. This is accomplished by exchanging positions of the brake valve and manifold
block on the motor. Secondly, the brake clutch assembly must be made effective for the opposite direction of rota-
tion. This is accomplished by reversing the inner race of the brake clutch assembly.
Figures 3 and 4 above show typical BG8 motor installations. Note that the only difference between the two draw-
ings is the motor is rotated 180° (the “belly” of the motor moves to the opposite side). If the motor shaft rotates
clockwise in Figure 3 when the hoisting port is pressurized, it will rotate counterclockwise in Figure 4.
