R E M O V IN G TH E com pressor from the vehicle but these
o p erations are covered later in this section as M AJOR REPAIR
P R O C E D U R E S because the system must be reclaim ed,
evacuated and recharged to com plete service.
Illustrations used in describing these operations show the

illustrate the various operations.
W hen servicing the com pressor, rem ove only the parts
that prelim inary diagnosis show s are in need of service. Refer
to F igures 2 and 5 for inform ation relative to part nam es and
location.
R em oval and installation of external com pressor parts,

COMPRESSOR CLUTCH PLATE AND HUB
ASSEMBLY
Remove or Disconnect
C lam p the holding fixture J 33026 in a vise and attach
com pressor to holding fixture with thum b screws
J 3 3 0 2 6 - 1 (Fig. 3).
With center screw forcing lip in place to thrust against
the end of the shaft, thread the Clutch Plate and Hub
A ssem bly Installer-R em over J 3 3 013-B into the hub.
Hold the body o f the rem over with a w rench and turn the
center screw into the rem over body to rem ove the clutch
plate and hub assem bly (Fig. 3).
NOTICE:
Do not drive or pound on the clutch hub or
shaft. Internal dam age to com pressor m ay result. The
forcing tip on J 330 1 3 -B rem over-installer center screw
must be flat or the end o f the shaft/axial plate assem bly
will be damaged.
Remove the shaft key and retain for reassem bly.
♦ + Install or Connect
Install the shaft key into the hub key groove (Fig. 4).
Allow the key to project approxim ately 3.2m m (1 /8 ")
out of the keyway. The shaft key is curved slightly to
provide an interference fit in the hub key groove.
Be sure the frictional surface o f the clutch plate and the
clutch rotor are clean before installing the clutch plate
and
hub
assembly.
Align the shaft key with the shaft keyw ay and place the
clutch plate and the hub assem bly onto the com pressor
