REASSEMBLY OF HYDRAULIC MOTOR:
If the hydraulic motor was disassembled, the following procedure should be followed for reassembly:
1) Clean all parts thoroughly before reassembly and apply grease liberally to all seals. Use only new seals (seal
kit Part No. 23131 for hydraulic motor).
2) Install six new pocket seals, item 887, on each thrust plate, item 885. The seal kit includes a single strip of
rubber. Using a sharp knife, cut lengths to fit the openings in the thrust plates. Press one of the thrust plates,
together with six pocket seals, onto the bearings, item 875, installed in the motor adaptor, item 800, so that
the pocket seals are against the motor adaptor.
3) Install a well-greased body seal, item 869, on each side of the gear housing, item 861. Slide the gear housing
together with the body seals, onto the motor adaptor, lined up on two dowel pins. Tap on tight using a soft
headed hammer.
4) Install the gear set, item 881, in the gear housing (the longer gear with the internal spline goes into the top
position).
5) Press the other thrust plate, complete with six new pocket seals, onto the bearings installed in the port end
cover so the pocket seals are facing the port end cover.
6) Install the port end cover, item 870, together with two bearings, item 875, and a new ring seal, item 877, onto
the gear housing, lined up on the two dowel pins, item 865. Tap on tight using a soft headed hammer. Install
and lightly torque four hex capscrews, item 951, and lockwashers, item 953, to approximately 50 ft-lb (70 Nm).
7) Plumb winch assembly to a hydraulic supply and torque motor capscrews according to the following
procedure:
- Ensure that circulation supply flow is being supplied to the brake housing.
- Run the winch , with no load, in the hoisting direction at reduced speed
(approximately 30% of maximum hydraulic volume).
- With winch running, evenly tighten four capscrews, item 951, to 200 ft-lb (270 Nm).
- Test motor operation by running winch at full speed in both directions.
IMPORTANT: Before operating the winch, add lubricating oil up to the level of the end cover oil fill port.
(Refer to INSTALLATION INSTRUCTIONS for location of fill port. Refer to APPENDIX A
for oil volume required.)
To ensure proper reassembly, run the winch in both directions without load.
LIFTING A LOAD WITH A NEWLY SERVICED WINCH WILL ENABLE AN
INSTALLATION OR SERVICE PROBLEM TO GO UNDETECTED AND
ALLOW THE LOAD TO DROP CAUSING PROPERTY DAMAGE,
SEVERE INJURY OR DEATH. TO ENSURE PROPER
REINSTALLATION, REFER TO PROCEDURES AND
TESTS DESCRIBED IN "INSTALLATION" AND
"OPERATING INSTRUCTIONS".
