26. INSTALLATION OF TRANSAXLE CASE(1) Place the selected spacers on the intermediate gear
and the differential’s bearing outer race. Also insert the
selected spacer between the output shaft bearing outerrace and the transaxle case.
(2) Set so that the threaded hole of the reverse idler gear
hshaft’s head is facing in the direction indicated in the

illustration.
NOTEIf there is a great deviation in the direction in which the
threaded hole is facing, it will be impossible to align thethreaded hole and the hole in the case after the
transaxle case is installed.
(3) Apply specified sealant to the clutch housing side of the
transaxle case.

out excess or discontinuity.(4) Install the transaxle case onto the clutch housing.
(5) Insert a Phillips screwdriver

reverse idler gear shaft with the bolt hole in the
transaxle case.(6) Install the reverse idler gear shaft bolt and tighten the
bolt by fingers.

56. INSTALLATION OF SHIFT RAIL ASSEMBLY
(1) Shift the Ist-2nd synchronizer sleeve into 2nd speed.
(2) Shift the
3rd-4th synchronizer sleeve into 4th speed.
(3)Fit the shift forks of shift rail assembly to their groove of
sleeves.
(4) Install the shift rails, rail holes of clutch housing.
(5) Turn the shift rails in the directions indicated by the
arrows in the order shown in the illustration, and
engage the shift lugs to control finger and interlock
plate.
55./54. INSTALLATION OF SPRING PINS
Using the special tool, drive the spring pins into position.
Make sure that the slit in the spring pin is aligned with the
shift rail centerline.
Caution
Do not reuse the spring pins.

24-24 HEATERS AND AIR CONDITIONING - Service Adjustment Procedures
COMPRESSOR NOISENUFIABWhen investigating an air conditioning related noise, you must
first know the conditions when the noise occurs. These
conditions are: weather, vehicle speed, in gear or neutral,
engine temperature or any other special conditions.
Noises that develop during air conditioning operation can oftenbe misleading. For example: what sounds like a failed front
bearing or connecting rod, may be caused by loose bolts, nuts,mounting brackets, or a loose clutch assembly. Verify acces-
sory drive belt tension (power steering, or alternator).
Improper accessory drive belt tension can cause a misleading
noise when the compressor is engaged and little or no noise
when the compressor is disengaged.
Drive belts are speed sensitive. That is, at different engine
speeds, and depending upon belt tension, belts can develop
unusual noises that are often mistaken for mechanical prob-
lems within the compressor.
Adjustment Procedures
(1) Select a quiet area for testing. Duplicate conditions as
much as possible. Switch compressor on and off several
times to clearly identify compressor noise.
To duplicate high ambient conditions (high head pressure),restrict air flow through condenser. Install manifold gauge
set to make sure discharge pressure doesn’t exceed 2,070
kPa (300 psi).
(2) Tighten all compressor mounting bolts, clutch mounting
bolt, and compressor drive belt. Check to assure clutch coilis tight (no rotation or wobble).
(3) Check refrigerant hoses for rubbing or interference that cancause unusual noises.
(4) Check refrigerant charge (See “Charging the System”).
(5) Recheck compressor noise as in Step 1.
(6) If noise still exists, loosen compressor mounting bolts and
retorque. Repeat Step 1.
(7) If noise continues, replace compressor and repeat Step 1.
