6. Turn the sprag assembly around and slide the inner
race (with 1 snap ring and bushing retainer) through
the bushing 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 retainer and snap ring. Make sure the snap
ring is properly seated in the groove.
7. Install the brake clutch assembly into the hoist.
Before installing the brake clutch, be sure the
inner race turns free in the same 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.
8. Install a new O-ring on the motor pilot. Rotate the
motor 180° from its original position and install it
onto the hoist. Install and tighten motor capscrews
to recommended 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.
NOTE:
On two speed motors, the
case drain and shift drain ports should be connected
directly to tank. DO NOT use the drain connection
on the brake valve. See “TWO SPEED MOTOR
CASE DRAIN PLUMBING” for additional informa-
tion.
11. If your hoist 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. The hoist
should operate smoothly in both directions. Refer to
“WIRE ROPE INSTALLATION” and properly install
wire rope onto the winch drum.
13.Before returning the hoist 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 controlled manner. If the winch does not perform
either of these functions, refer to “TROUBLE
SHOOTING” for additional information.
