D 1P-0510 Driver Gp 1
E 1U-6396 O-Ring Assembly Compound 1
F 1P-1854 Retaining Ring Pliers 1
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. A reconditioning procedure should not be degraded
because of a low cost component such as an O-ring or a gasket. Use Tooling (E) during the
assembly procedure.
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: Apply a light film of SAE 10W oil to all components before assembly.
