Before any part is removed from the winch or drive gear-
box, all service instructions should be read and under-
stood.
Work in a clean, dust free area as cleanliness is of utmost
importance when servicing hydraulic equipment.
Inspect all replacements parts, prior to installation, to de-
tect any damage which might have occurred in shipment.
Use only genuine BRADEN replacement parts for opti-
mum results. Never reuse expendable parts such as O-
rings and oil seals.
Inspect all machined surfaces for excessive wear or dam-
age before reassembly operations are begun.
Lubricate all O-rings and oil seals with gear oil prior to
installation.
Lubricate all bearings with an oil soluble grease prior to
assembly.
Use a sealing compound on the outside surface of oil
seals and a light coat of thread sealing compound on pipe
threads. Avoid getting sealing compound inside parts or
passages which conduct oil.
Before beginning to disassemble the winch or drive gear-
box, remove the wire rope, drain the oil and clean the out-
side surfaces to avoid contaminating gears and bearings.
Item numbers shown in service procedures are referenced
to the exploded-view drawing in this manual.
WINCH DISASSEMBLY
1. Stand the winch of the end opposite the motor. Re-
move the hydraulic hose that connects the brake valve
and motor to the brake release port. Remove the four
capscrews securing the motor to the winch and lift off
the motor/brake valve assembly. Remove and discard
the O-ring installed on the outside of the motor pilot.
2. Remove the four capscrews from the motor adapter
and remove the motor adapter (Item 27) from the drive
gearbox. Remove and discard the O-ring (Item 26)
from the motor adapter.
3. Remove the 10 capscrews and lockwashers securing
the end bracket (Item 25) to the gearbox.
4. Remove the 24 capscrews and lockwashers securing
the tie plates (Item 1) to both end brackets and remove
the tie plates. The tie plates have two dowel pins in each
end and may have to be lightly tapped or pried from the
end brackets. Install four large C-clamps around the
drum support end bracket (Item 2) and the drum flange.
This will prevent the end bracket and drum from sepa-
rating when the motor end bracket and winch drive are
removed.
5. Lift the motor end bracket (Item 25) from the drum/drive
assembly.
