6. Turn the sprag assembly around and slide the inner
race (with 1 snap ring and bushing retainer) through
the bushings and sprag clutch (the race will have to be
rotated in the free-wheeling direction to start it through
the sprag clutch). Install the remaining bushing retain-
er and snap ring. Make certain the snap ring is prop-
erly seated in the groove.
7. Before installing the brake clutch, be sure the inner
race turns free in the opposite direction the drum will
turn to haul-in wire rope. An easy way to check the
rotation is to hold the outer race in one hand and
rotate the inner race from the motor side. Install the
brake clutch.
NOTE:
The snap ring installed in the bore of the inner
race is not centered in the splines. The long spline
engagement end
MUST
always install toward the
motor to permit proper positioning of the brake clutch
within the internal brake assembly.
8. 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 rec-
ommended torque.
9. 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.
10. Connect the motor case drain hose to the motor case
drain port.
11. 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).
12. 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 INSTALLA-
TION” and properly install rope onto the winch drum.
13. Before returning the winch to full service, a light load
should be lifted and held a few feet off the ground to
be sure the static brake is functioning properly. The
winch should also be able to slowly lower the load in
a smooth and controlled manner. If the winch does
not perform either of these functions, refer to “TROU-
BLESHOOTING” for additional information.
Assemble so that inner race
freewheels in the opposite
direction of desired cable
drum rotation for hoisting
when viewed from motor side.
Be certain the snap ring is seated in the groove in the
splined bore of the inner race. This snap ring will keep
the brake clutch assembly correctly positioned in the
center of the friction brake pack. Binding of the brake or
brake failure may occur if this snap ring is omitted.
