WARNING

Wear eye protection when repairing pilot valve assembly. Pilot valve assembly contains springs under com-

pression. Failure to exercise caution during disassembly and assembly may result in injury to personnel.

CAUTION

To prevent contamination of hydraulic system, keep work area and components of pilot valve assembly

clean.

NOTE

This work package describes and illustrates repair of pilot valve assembly for a machine equipped with rip-

per. If machine has no ripper, repair is similar: ripper pilot valve is not present; only the blade tilt pilot

valve is present.

DISASSEMBLY

NOTE

Capscrews and washers used for holding housings on pilot valves were removed when ripper and blade

control levers were disconnected during removal of pilot valve assembly. Keep these parts with respec-

tive pilot valve to ensure correct installation.

Tag pilot valves, inlet and outlet manifolds and all other parts to ensure correct assembly.

Remove two housings (1) from top of pilot valve assembly (2). Remove housing O-ring (3) and shaft seal (4) from both

housings. Discard O-rings and seals.
