AIR MOTOR SECTION SERVICE

Service is divided into two parts - 1.Pilot Valve, 2.Major Valve.

GENERALREASSEMBLY NOTES:

SAir Motor Section Service is continued from Fluid Section repair.

SInspect and replace old parts with new parts as necessary. Look for deep scratches on metallic surfaces, and nicks or cuts in ``O￿rings.

STake precautions to prevent cutting ``O￿rings upon installation.

SLubricate ``O￿rings with Key-lube or equivalent.

SDo not over-tighten fasteners, refer to torque specification block on view.

SRe-torque fasteners following restart.

PILOT VALVE DISASSEMBLY

1.Remove ￿104￿ retaining ring.

2.Remove ￿123￿ screws, ￿122￿ ``O￿rings.

3.Remove ￿118￿ piston rod, ￿121￿ sleeve bushing, ￿119￿ ``O￿rings, and ￿120￿ spacers from the ￿101￿ motor body.

4.Remove ￿103￿ sleeve and ￿102￿ ``O￿ring.

PILOT VALVE REASSEMBLY

1.Replace ￿102￿ ``O￿￿ring if worn or damaged and reinstall ￿103￿ sleeve.

2.Install one of the ￿121￿ sleeve bushings, ￿119￿ ``O￿￿rings, ￿120￿ spacers, and the remaining ￿121￿ bushing.

3.Carefully push ￿118￿ pilot rod into bushings etc. and retain on each end with the two ￿122￿ ``O￿￿rings, retain with ￿123￿ screws.

4.Replace ￿104￿ retaining rings.
