SERVICE PRECAUTIONS
• Before any part is removed from the winch, all service
instructions should be read and understood.
• Work in a clean, dust free area as cleanliness is of
utmost importance when servicing hydraulic equip-
ment.
• Inspect all replacements parts, prior to installation,
to detect any damage which might have occurred in
shipment.
• Use only genuine BRADEN replacement parts for
optimum results. Never reuse expendable parts such
as oil seals and O-rings.
• Inspect all machined surfaces for excessive wear or
damage . . . before reassembly operations are begun.
• Lubricate all O-rings and oil seals with gear oil prior to
installation.
• Use a sealing compound on the outside surface of oil
seals and a light coat of thread sealing compound on
pipe threads. Avoid getting thread compound inside
parts or passages which conduct oil.
• Thoroughly clean all parts in a good grade of non-
flammable safety solvent. Wear protective clothing as
required.
After troubleshooting the winch and its hydraulic system
as covered in the “Troubleshooting” section, and the
problem is determined to be in the winch, use the fol-
lowing procedure to disassemble the winch.
1. Remove the wire rope from the winch drum and
align the drain hole in the drum with a hole in the
support side plate before removing the hoses and
mounting bolts. After the winch is removed from its
mounting, thoroughly clean the outside surfaces.
To drain the oil, install a short piece of 1-inch pipe
in the larger threads of the drain hole. If necessary,
insert a bar into the anchor pocket and manually
rotate the drum in the direction to hoist a load until
the drain holes are aligned.
2. Use a 5/16-inch Allen wrench to remove the drain
plug through the pipe. Drain the oil into a suitable
container and dispose of used oil in an environmen-
tally friendly manner.
3. Begin disassembly by removing the oil level plug
and standing the winch on the bearing support end.
Tag and remove the hydraulic hoses that connect
the brake valve and manifold to the brake cylinder.
4. Remove the capscrews securing the motor, and lift
the motor off the winch. Remove and discard the
O-ring installed on the pilot of the motor.
5. Remove the brake clutch assembly from the motor
support. Refer to “Brake Clutch Service” for addi-
tional information.
