a.
This section contains instructions for removal and installation of major components of the winch assembly to
facilitate repair and overhaul procedures. Complete repair and overhaul instructions are covered in the following
sections of this manual.

The engine and torque converter are mounted on the same sub frame which is then mounted on the winch
frame. Normally, maintenance requiring disassembly of either of these major components will be accomplished by
removing the complete assembly from the winch frame. Remove and move the engine and torque converter assembly
mounted on the engine sub frame to the maintenance shelter prior to further disassembly.

Cap or cover all disconnected air and fluid lines and the open end of the chain case on the winch
to prevent accumulation of dirt, sand and water in the lines and drive chain case. Cap or cover all
engine and torque ports, lines and the chain drive sprocket until the engine assembly is moved to
a maintenance shelter.

The torque converter can be removed from engine assembly sub frame and engine for repair
without removing engine assembly.
