AIR SECTION SERVICE
Service is divided into two parts - 1. Pilot Valve, 2. Major Valve.
GENERAL SERVICE NOTES:
S Air Motor Section Service is continued from step 8 of the Fluid Sec-
tion Disassembly.
S It is not necessary to remove the Fluid Section Ends to gain access
to the Air Motor Major Valve Section.
S In most cases, problems of an air control nature will reside in the Air
Valve area.
S 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.
S j SERVICE KIT NOTE: Only two replacement “O” rings are supplied
in the 637338 and 637339-( ) kits.
PILOT VALVE DISASSEMBLY
S 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.
2. A light tap on (118) actuator pin should expose the opposite (121)
plug and (167) pilot piston.
3. Remove (170) piston sleeve and inspect the inner bore for damage.
PILOT VALVE REASSEMBLY
S Lubricate all soft parts, spool and bores with Key-Lube grease upon
reassembly.
1. Assemble the trailing (102) “O” ring to (103) sleeve and assemble
sleeve into motor center body, pushing thru far enough to expose
“O” ring groove on opposite end.
2. Assemble (102) “O” ring to (103) sleeve and push sleeve onto motor
center body.
3. Assemble (2) “O” ring to (1) rod and assemble into (103) sleeve.
4. Assemble (171 and 172) “O” rings to (170) piston sleeve and as-
semble into (101) center body. NOTE: Assemble sleeve with small
i.d. into center body.
5. Assemble two (168) “O” rings and (169) “U” cup to (167) pilot piston
(note the lip direction of “U” cup) and assemble into (170) piston
sleeve.
6. Assemble (173) “O” rings and (174) “U” cups (note lip direction) to
(121) plugs.
7. Assemble (118) actuator pins to (121) plugs and assemble (121)
plugs into (101) center body.
8. Assemble (104) plates to (101) center body, securing with (123)
screws.
9. Reassemble fluid section parts.
