been replaced, you must perform the differential
bearing preload shim adjustment. If the transaxle
case has been replaced, you must perform both pro-
cedures.
GENERAL RULES ON SERVICING BEARINGS
(1) Use extreme care when removing and install-
ing bearing cups and cones. Burrs or nicks on the
bearing seat will give a false end play reading while
gauging for proper shims. Improperly seated bearing
cups and cones are subject to low±mileage failure.
(2) Bearing cups and cones should be replaced if
they show signs of pitting or heat distress. If distress
is seen on either the cup or bearing rollers, both cup
and cone must be replaced.(3) Bearing preload and drag torque specifications
must be maintained to avoid premature bearing fail-
ures. Used (original) bearings may lose up to 50% of
their original drag torque after break in. All bearing
adjustments must be made with no other component
interference or gear intermesh.
(4) Replace bearings as a pair: If one differential
bearing is defective, replace both differential bear-
ings.
(5) Bearing cones must not be reused if removed.
(6) Turning torque readings should be obtained
while smoothly rotating in either direction.
INTERMEDIATE SHAFT BEARING PRELOAD
The intermediate shaft preload must be checked if
the housing, intermediate shaft, bearing plate, bear-
ings, or transaxle case are replaced.
The intermediate shaft bearing preload procedure
must be done with the transaxle out of the vehicle
and on a bench.
(1) Remove end cover (Fig. 226).
(2) Remove 5th shift fork roll pin (Fig. 227).
(3) Use Special Tool 6252 to hold 5th gear. Remove
input shaft 5th gear nut (Fig. 228).
(4) Remove 5th gear synchro snap ring (Fig. 229).
(5) Remove 5th gear synchro, synchro plate, and
fork.
(6) Remove 5th drive gear off of the input shaft
(Fig. 230).
(7) Remove bearing retainer plate (Fig. 231).
(8) Remove bearing preload shim (Fig. 232).
(9) Bolt down the bearing support plate in two
places (verify dowels are in place).
(10) Seat the intermediate bearing cup against the
bearing.
(11) Measure depth of intermediate bearing cup
with dial depth gauge (Fig. 233).

REMOVAL AND INSTALLATION (Continued)

CAUTION: Do not use screwdrivers between the
clutch plate assembly and pulley to remove front
plate as this may damage the front plate assembly.
(2) Tap the clutch plate with a plastic hammer and
remove clutch plate and shim (Fig. 26).
(3) Remove pulley retaining snap ring with snap
ring pliers (C-4574), and slide pulley assembly off of
compressor (Fig. 27).
(4) Remove coil wire clip screw and wire harness.
(5) Remove snap ring retaining field coil onto com-
pressor housing (Fig. 28). Slide field coil off of com-
pressor housing.
(6) Examine frictional faces of the clutch pulley
and front plate for wear. The pulley and front plate
should be replaced if there is excessive wear or scor-
ing. If the friction surfaces are oily, inspect the shaft
nose area of the compressor for oil and remove the
felt from the front cover. If the compressor felt is sat-
urated with oil, the shaft seal is leaking and will
have to be replaced.(7) Check bearing for roughness, excessive leakage
or grease. If grease from bearing has contaminated
the faces of the pulley or front plate, they should be
replaced. If the bearing is rough or binds, replace
clutch pulley and front plate assembly.

REMOVAL AND INSTALLATION (Continued)

CAUTION: The clutch pulley and the front plate
were mated at the factory by a burnishing opera-
tion. No attempt should be made to separately
replace either part. This will result in clutch slip-
page due to insufficient contact area.
INSTALLATION
(1) Align pin in back of field coil with hole in com-
pressor end housing, and position field coil into place.
Make sure that lead wires are properly routed, and
fasten with the wire clip screw.
(2) Install field coil retaining snap ring with snap
ring pliers. The bevel side of the snap ring facing
outward. Also both snap ring eyelets must be to the
right or left of the pin on compressor. Press snap ring
to make sure it is properly seated in the groove.
CAUTION: If snap ring is not fully seated it will
vibrate out, resulting in a clutch failure and severe
damage to the front face of the compressor.
(3) Install pulley assembly to compressor. If neces-
sary, tap gently with a block of wood on the friction
surface (Fig. 29).
CAUTION: Do not mar the pulley frictional surface.
(4) Install pulley assembly retaining snap ring
(bevel side outward) with snap ring pliers. Press the
snap ring to make sure it is properly seated in the
groove.
(5) If the original front plate assembly and pulley
assembly are to be reused, the old shim(s) can beused. If not, place a trial stack of shims, 1 mm (0.040
in.) thick, on the shaft against the shoulder.
(6) Install front plate assembly onto shaft.
(7) With the front plate assembly tight against the
shim(s), measure the air gap between front plate and
pulley face with feeler gauges. The air gap should be
between 0.5 and 0.9 mm (.020 and .035 inch) If
proper air gap is not obtained, add or subtract shims
until desired air gap is obtained.
(8) Install compressor shaft bolt. Tighten to
17.562 N´m (155620 in. lbs.).
NOTE: Shims may compress after tightening shaft
nut. Check air gap in four or more places to verify if
air gap is still correct. Spin pulley for final check.
CLUTCH BREAK-IN
After a new clutch has been installed, check the
voltage and amperage to the clutch (determine it to
be satisfactory). Then cycle the A/C clutch approxi-
mately 20 times (5 sec. on and 5 sec. off). For this
procedure, set the system to the A/C mode, using
high blower, and engine rpm at 1500-2000. This pro-
cedure (burnishing) will seat the opposing friction
surfaces and provide a higher clutch torque capabil-
ity.
CONDENSER ASSEMBLY
WARNING: THE REFRIGERATION SYSTEM MUST
BE COMPLETELY EMPTY BEFORE PROCEEDING
WITH THIS OPERATION.
NOTE: Special effort must be used to keep all
R-134a system components moisture-free. Moisture
in the oil is very difficult to remove and will cause a
reliability problem with the compressor.
