AIR SECTION SERVICE
Serviceis divided into two parts - 1. Pilot Valve,2. Major Valve.
GENERALSERVICE NOTES:
SAirMotor Section Service is continued from step 8 of the Fluid Sec-
tionDisassembly.
SItis not necessary to remove the Fluid Section Ends to gain access
tothe Air Motor Major Valve Section.
SInmost cases, problems of an air control nature will reside in the Air
Valvearea.
SRemovalof the Fluid Sections is required to install all of the parts in-
cludedin the Air Section Service Kit, if this is the case, follow steps 1
thru8 of the Fluid Section Disassembly on both sides and isolatethe
AirSection.
SjSERVICEKIT NOTE: Only two replacement “O” rings are supplied
inthe 637338 and 637339-( ) kits.
PILOT VALVEDISASSEMBLY
SNOTE:Both outer pump Fluid Sections must be removed to access
thePilot 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)
plugand (167) pilot piston.
3. Remove (170) piston sleeve and inspect the inner bore for damage.
PILOT VALVEREASSEMBLY
SLubricateall soft parts, spool and bores with Key-Lube grease upon
reassembly.
1. Assemble the trailing (102) “O” ring to (103) sleeve and assemble
sleeveinto 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
centerbody.
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-
sembleinto (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)
plugsinto (101) center body.
8. Assemble (104) plates to (101) center body, securing with (123)
screws.
9. Reassemble fluid section parts.
