9. Major internal mechanism assembly.
10. Suction reed valve - front, rear.
11. Discharge valve assembly - front, rear.
12. Gasket service kit - containing all gaskets,
seals, O-rings, etc.
13. Shaft seal kit.
14. Nuts - head to shell and shaft.
15. Retainer rings.
16. Cylinder locator pins.
17. Valve and head locator pins.
18. Service type discharge cross-over tube kit.
All service parts are protected by a pre-
servation process and packaged in a manner
that will eliminate the necessity of cleaning,
washing or flushing of parts to remove pre-
servation materials. Parts can be used in mecha-
nism assembly just as they are removed from
service package.
Certain parts are identified on the piece part
to denote their size or dimension. This applies
to piston shoe discs and shaft thrust races.
Gasket service kit contains suction cover gas-
ket, shaft seal O-rings, head to shell O-rings,
oil tube inlet O-ring, and discharge crossover
tube O-rings. This kit should be used to replace
all seals and gaskets whenever a compressor
is overhauled or an individual component is
replaced.
There is an optional method of handling one
of the major internal components -- the cylin-
der assembly. A service cylinder assembly, in-
cluding bearings, and both front and rear halves
of cylinders mated together, is available for
service. There may be occasions where it would
be desirable to use this assembly rather than
the complete internal assembly. In case it is
used, the gaging and parts selection operations
will have to be performed as described in Note
40.
An inspection should be made of the internal
mechanism assembly to determine if any service
operations should be performed. A detailed in-
spection of parts should be made to determine
if it is economically feasible to replace them.
It may be more economical to replace the entire
internal mechanism assembly, rather than re-
place parts.
Before proceeding with disassembly, wipe ex-
terior surface of compressor clean.
All oil in compressor should be drained and
measured. This oil should then be discarded.
Assist draining by positioning compressor with
oil drain plug down, open suction connector and
rotate drive shaft two or three times.
38. Compressor Internal
Mechanism Removal
1. Remove clutch plate and hub assembly as
described in Note 32a.
2. Remove pulley and bearing assembly as
described in Note 33a.
3. Remove clutch coil and housing assembly
as described in Note 35a.
4. Remove shaft seal as described in Note 36a.
5. Invert compressor and Holding Fixture,
J-9396, with front end of compressor shaft down.
NOTE: Additional oil may leak from com-
pressor at this time. All oil must be drained
into a container so that total amount can be
measured. A liquid measuring cup may be
used for this purpose.
6. Remove four lock nuts from threaded studs
on compressor shell and remove rear head.
NOTE: Tap uniformly around rear head if
head is binding.
7. Wipe excess oil from all teflon gasket sur-
faces on rear head casting webs, and examine
gasket surfaces, Fig. 13-46. If any damage is
observed, head should be replaced.
8. Remove suction screen and examine for any
damage or contamination. Clean or replace if
necessary.
9. Paint an identifying mark (Prussian blue or
other suitable marking material may be used) on
Fig. 13-46 Teflon Gasket Surfaces on Rear Head
