Note: Cleanliness is an important factor. Before assembly, all parts should be thoroughly
cleaned in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be
used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect
all parts. If any parts are worn or damaged, use new parts for replacement. All disassembly
and all assembly procedures must be performed on a clean work surface and in a clean
hydraulic area. Keep cleaned parts covered and protected at all times.
Note: O-rings, gaskets, and seals should always be replaced. A used O-ring may not have
the same sealing properties as a new O-ring. Use Tooling (L) during the assembly
procedure.
Note: Some of the images that are in this procedure do not show the sprocket assembly that
is attached to the final drive housing. If necessary, the weights that are given include the
weight of the sprocket assembly.
Note: Apply a light film of hydraulic oil to all components before assembly.
