PILOT VALVE REASSEMBLY

1.Replace two (102) “O” rings, 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.

MAJOR VALVE DISASSEMBLY

1.Remove (107) plate and (108 and 117) gaskets.

2.On the side opposite the air inlet, push on the inner diameter of (111) spool. This will force the (109) piston out. Continue pushing the (111) spool and remove. Check for scratches and gouges.

3.Reach into the air section (exhaust side) and remove (116) spacer, (115) spacers, (113) “O” rings, (114) “O” rings, (112) wash- ers. etc. Check for damaged “O” rings.

PILOT VALVE DISASSEMBLY

1.Remove (104) retaining ring.

2.Remove (123) screws and (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” rings.

MAJOR VALVE REASSEMBLY

1.Replace (112) washer, (114) “O” ring and (113) “O” ring onto (115) spacer and insert etc. NOTE: Be careful to orient spacer legs away from blocking internal ports.

2.Lubricate and carefully insert (111) spool.

3.Install (117) gasket and (107) plate.

4.Lubricate and install (110) packing cup and insert (109) piston into (air inlet side) cavity. The (110) packing cup lips should point outward.
