Repairs
General
This section includes the removal and disassembly of all
major assemblies, inspection of components, and reas-
sembly and installation. The wear points detailed in Figure
4-8 should be inspected at the time of disassembly so that
worn parts may be ordered and replaced prior to reassem-
bly. If the winch is to be completely overhauled, perform
the removal, disassembly, inspection and reassembly
procedures in the sequence of the following paragraphs.
NOTE: Always use the troubleshooting procedures
given in Section 2 to locate a malfunction before per-
forming a major overhaul of the unit. Make all checks
in a systematic manner. Haphazard checking wastes
time and can cause further damage.
Review and perform any adjustments that may be the
cause of a malfunction (refer to Section 3).
Use new seals, gaskets and O-rings when installing
components.
Cleanliness is of extreme importance in the
repair and overhaul of any hydraulic unit. Be-
fore attempting any repairs, the exterior of the
winch must be thoroughly cleaned to prevent
the possibility of contamination.
Winch Removal
1.
Drain the oil (MIL-PRF-2105E) from the winch.
2.
Remove the arch or fairlead from the winch. If these
accessories are left on the winch, the winch will not
remain level when lifted from the tractor.
3.
Remove the wire rope from the drum. Clean the
outside of the winch and the area where the winch
contacts the tractor.
Be careful when you remove the wire rope
from the drum. The end of the wire rope can
move like a compressed spring, causing an
injury when the ferrule is released from the
drum.
4.
Disconnect hoses and wire rope harness from tractor.
5.
Connect slings and a crane or lifting device to the
winch. Install lifting eyes into the lifting holes provided
in the frame.
The slings and crane used to lift the winch
must have a minimum lifting capacity of 1500
kg (3000 lb.).
6.
Remove the mounting hardware securing winch to
tractor.
NOTE: When removing the mounting nuts or cap-
screws, loosen all nuts slightly, then pry winch away
from mounting pad. Loosen all nuts again and pry
winch again. Continue this sequence until winch can
be removed.
Winch Disassembly
Most repairs require disassembly of the winch, although
many major assemblies can be removed from the winch
with the winch still on the tractor. The procedures in this
section describe a complete unit overhaul with the winch
removed from the tractor.
