COMPRESSOR
The compressor is a two-cylinder, reciprocating-
type designed specifically for the Chrysler Air-Condi-
tioning System. Service parts are available so that
the compressor can be repaired in the field.

with the nomenclature of the parts. Some parts are
serviced individually and some are serviced in pack-
ages which include two or more service parts. Refer
to the parts book for this information.
CAUTION: T h e refrigerant o i l used
in
t h e compres-
sor is carried
through
t h e e n t i r e system
by
t h e re-
frigerant. Some o f this o i l
will
be
trapped and re-
tained
in
t h e system w h e n t h e refrigerant is dis-
charged f o r testing o r unit replacement.
If
t h e com-
pressor i s t o be removed f o r repair o r replacement,
measure t h e refrigerant o i l level
in
the compressor
before t h e compressor i s removed f r o m t h e vehicle
so t h a t t h e same o i l level can be established w h e n
t h e new o r repaired compressor i s installed o n t h e
vehicle. Too m u c h refrigerant o i l
in
t h e system can
cause abnormal operating pressures and reduce t h e
performance o f t h e e n t i r e system.
Complete disassembly and assembly of the com-
pressor must be performed with the compressor re-
moved from the vehicle. However, on some models
the valve plate and crankshaft gas seal assemblies
can be replaced with the compressor installed on the
vehicle.
CAUTION: T h e system must be completely dis-
charged before attempting t o p e r f o r m
airy
disas-
sembly o r repair service t o t h e compressor.
Cleanliness is extremely important. The work area
must be clean and free of air-borne dust and dirt. All
parts must be thoroughly cleaned and blown dry be-
fore reassembly.
Do not use air to dry the crankshaft front main
bearing. Wash the bearing in
clean
mineral spirits and
shake out all excess cleaning fluid. Saturate the bear-
ing with
clean refrigerant o i l
and assemble immedi-
ately. Any dirt in the front main bearing assembly
will cause noisy operation and possible damage to the
bearing.
CAUTION: Before reassembly o f any
unit,
a l l con-
tact surfaces must be liberally coated
with
clean
re-
frigerant oil. Refrigerant o i l must be kept
in
a
sealed container
until
