AIR SECTION SERVICE

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

GENERAL SERVICE NOTES:

Air Motor Section Service is continued from step 8 of the Fluid Sec-

tion Disassembly.

It is not necessary to remove the Fluid Section Ends to gain access

to the Air Motor Major Valve Section.

In most cases, problems of an air control nature will reside in the Air

Valve area.

Removal of the Fluid Sections is required to install all of the parts in-

cluded in the Air Section Service Kit, if this is the case, follow steps 1

thru 8 of the Fluid Section Disassembly on both sides and isolate the

Air Section.

SERVICE KIT NOTE: Only two replacement "O" rings are supplied

in the 637338 and 637339-( ) kits.

PILOT VALVE DISASSEMBLY

NOTE: Both outer pump Fluid Sections must be removed to access

the Pilot Section parts (see figure 3, page 7).

1. Remove two (123) screws and (104) plate from both sides of the

(101) motor center body.
