13. Turn the two jam nuts on the rotation sensor (144)
to produce an installed length of the threads of 1.21
in. (30.7 mm) measured from the bottom of the sen-
sor to the washer against the jam-nut. Apply a small
amount of general purpose grease to the threads
and install the sensor assembly into the motor end-
plate. Tighten until just snug to avoid damage to the
sensor.
14. Install a new o-ring (98) onto the motor pilot and
install the motor onto the motor adapter/brake cylin-
der assembly with capscrews and washers (90 &
91). Evenly tighten the capscrews (90) to 282 lb.-ft.
(382 N-m) torque.
15. Install the hydraulic lies, removed during disassem-
bly, from the brake valve and motor lowering port
manifold to the brake release port on the brake
cylinder.
16. After the hoist assembly is complete, check all fas-
teners and hydraulic fittings to make certain they
have been properly tightened. Refill the hoist with
the recommended planetary hoist gear oil.
17. 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
hoist should also be able to slowly lower the load in
a smooth and controlled manner. If the hoist does
not perform either of these functions correctly, refer
to the Trouble Shooting section of this manual.
