Use only NEW, moisture-free refrigerant oil in A/C systems.
Refrigerant oil is highly refined with a very low moisture content.
Oil container must be tightly closed when not in use, or moisture from
air will be absorbed into refrigerant oil.
Refrigerant R-134a systems use Polyalkylene Glycol (PAG)
refrigerant oil. Using a mineral oil based lubricant with R-134a
systems will result in A/C compressor failure due to lack of proper
lubrication.
All compressors have different lubrication requirements and
use different Polyalkylene Glycol (PAG) refrigerant oils. Use only the\
specified PAG refrigerant oil for the appropriate system and A/C
compressor. Always check the underhood A/C specification label or A/C
compressor label before adding refrigerant oil to A/C
compressor/system. See listing of refrigerant oils currently available
from the vehicle manufacturers.
NOTE: PAG oil absorbs moisture very rapidly, 2.3-5.6 percent by
weight as compared to a mineral oil absorption rate of .005
percent by weight.
CHRYSLER CORP., JEEP & EAGLE
Use ND-8 PAG oil, SUN PAG 56 oil, SP-10 PAG oil, or SP-20 PAG
oil.
FORD MOTOR CO.
Use YN-12B or YN-12C PAG Refrigerant Oil (specification WSH-
M1C231-B) or SP-20 PAG Oil (specification WST-M1C231-B2).
GENERAL MOTORS
On all models except Saturn, use PAG Refrigerant Oil (Part
No. 12345923). On Saturn, use Saturn PAG refrigerant oil.
SERVICING PRECAUTIONS
DISCHARGING SYSTEM
Discharge A/C system, using approved refrigerant
recovery/recycling equipment before loosening any fittings. Follow
refrigerant recovery/recycling equipment manufacturer's instructions.
DISCONNECTING LINES & FITTINGS
After system is discharged, carefully clean area around all
fittings to be opened. Always use 2 wrenches when loosening or
tightening fittings. Some refrigerant lines are connected with a
spring-lock coupling. Special tools may be required to disconnect
lines. To prevent dirt and moisture from entering system, cap all
openings as soon as lines are removed. DO NOT remove service valve
caps until ready to connect lines and fittings.
NOTE: All R-134a based systems use 1/2-16 ACME threaded fittings.
Ensure all replacement parts match the connections of the
system being worked on.
CONNECTING LINES & FITTINGS
Always use new a gasket or "O" rings when connecting lines or

Removal
1) Discharge A/C system, using approved refrigerant
recovery/recycling equipment. Remove compressor. Using a spanner
wrench or clutch holder, remove clutch plate bolt. Discard bolt.
Thread an 8-mm bolt into clutch plate and remove clutch plate and
shims.
2) Remove shaft felt seal. Using low pressure compressed air
and a lint-free cloth, thoroughly clean seal inside and outside of
compressor nose area. Using Snap Ring Remover (T89P-19623-DH), rotate
eye of snap ring. Pull up snap ring while holding snap ring at an
angle.
3) Position Shaft Seal Remover (T89P-19623-BH) over
compressor shaft. Push shaft seal remover downward against seal.
Ensure end of shaft seal remover engages inside of seal.
4) Rotate shaft seal remover handle clockwise to expand
remover tip inside seal. Pull shaft seal from compressor.
Installation
1) Lubricate shaft seal protector and shaft seal with
refrigerant oil. Replacement Seal Kit (19D665) includes Shaft Seal
Protector (T94P-19623-F).
2) Coat shaft seal and protector with clean refrigerant oil.
Install shaft seal on shaft seal protector so lip of seal is toward
large end of shaft seal protector. Install shaft seal protector onto
compressor shaft.
3) Using Shaft Seal Replacer (T89P-19623-AH), slowly push
shaft seal down until it is seated. Remove shaft seal installer and
protector. Install new shaft seal snap ring. Rotate compressor shaft
about 10 revolutions and leak test shaft seal installation.
4) Install new shaft seal felt. Install clutch plate. Install
new clutch plate bolt, and tighten it to 98-123 INCH lbs. (11-14 N.m).\
5) Using a feeler gauge, measure air gap (in 3 places)
between clutch plate and pulley assembly mating surface. Air gap
should be 0.014-0.033" (0.36-0.84 mm). If air gap is not as specified,\
add or remove shims as necessary.
HARRISON HD6/HT6 & HD6/HR-6HE 6-CYL., V5 5-CYL. & V7 7-CYL.
CLUTCH ASSEMBLY
CAUTION: DO NOT hammer on compressor shaft to remove clutch plate, as
compressor damage will result.
Removal
1) Remove compressor from vehicle. Place compressor in
Holding Fixture (HD6/HT6 and HD6/HR-6HE compressor use J-33026; on V5
or V7 compressor use J-34992 or J-41790). On V5 or V7 compressor,
remove dust cover (if equipped). Use Clutch Plate Spanner (J-33027-A)\
to hold clutch plate and remove compressor shaft nut using Shaft Nut
Socket (J-33022). See Fig. 2 or 3.
2) On all compressors, using Clutch Plate Remover/Installer
(J-33013-B), remove compressor clutch plate and hub. See Fig. 2 or 3.
Hold remover body and turn center screw into remover body to remove
clutch plate and hub. Ensure forcing tip on remover/installer center
screw is flat or end of shaft/axial plate will be damaged. Remove
shaft key.
3) Remove snap ring. Install Puller Guide (J-33023-A) on
front head. Position Pulley and Bearing Puller (J-41552 for HD6/HT6
and HD6/HR-6HE or J-33020 for V5 or V7 compressor) into inner circle
of slots on pulley assembly. Turn puller clockwise in slots. Tighten
puller and remove pulley assembly.
