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-
S
tion Disassembly.
It is not necessary to remove the Fluid Section Ends to gain access
S
to the Air Motor Major Valve Section.
In most cases, problems of an air control nature will reside in the Air
S
Valve area.
Removal of the Fluid Sections is required to install all of the parts in-
S
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
S
j
in the 637338 and 637339-( ) kits.
PILOT VALVE DISASSEMBLY
NOTE: Both outer pump Fluid Sections must be removed to access
S
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.
