Drive Pinion
Remove the stopper for the overrunning clutch by us-
ing a pipe as shown in the figure.
Adjustment of Pinion Gap
1. Disconnect the wiring from terminal (M).
2. Apply battery power to the terminal (S) and ground
the starter motor body, the pinion will eject outward
and then stop.
3. Measure the clearance (pinion gap) between the
pinion and the stopper.
Pinion gap: 0.5—2.0 mm (0.020—0.079 in)
Caution
Do not let electricity flow continuously for
more than 10 seconds.
If the pinion gap is not within the specified range,
make the adjustment by increasing or decreasing
the number of washers used between the magnetic
switch and the drive housing. The gap will become
smaller if the number of washers is increased.
Caution
Do not use the washers
(0.079 in) in all.
more than 2 mm
INSPECTION
Armature Coil
1. Ground of the armature coil
(1) Check for continuity between the commutator
and the core by using a circuit tester.
(2) Replace the armature if there is continuity.

2. Apply battery power to the terminal (S) and ground
the starter motor body, the pinion will eject outward
and then stop.
3. Measure the clearance (pinion gap) between the
pinion and the stopper.
Note
Be careful not to let electricity flow continu-
ously for more than 10 seconds.
Pinion gap: 0.5—2.0 mm (0.020—0.079 in)
4. If the pinion gap is not within the specified range,
make the adjustment by increasing or decreasing
the number of washers used between the magnetic
switch and the drive housing. The gap will become
smaller if the number of washers is increased.
Caution
Do not use the washers more than plates.
INSPECTION
Armature Coil
1. Ground of the armature coil
Check for continuity between the commutator and
the core by using a circuit tester. Replace the ar-
mature if there is continuity.
4BG05-081
2. Vibration of the commutator
Plate the armature on V blocks, and measure the
vibration by using a dial gauge. If the vibration is
Limit or more, repair so that is standard by using
a lathe, or replace the armature.
Standard vibration: 0.05 mm (0.002 in)
Limit: 0.4 mm (0.018 in)
Note
Before checking, be sure than there is no play
in the bearings.

ON-VEHICLE INSPECTION
1. Connect the manifold gauge set.
2. Run the engine at 1,500 rpm.
3. Check the compressor flow:
a) High pressure is not low and low pressure is not
higher than normal.
b) Metallic sound.
c) Check to be sure that the high-pressure and low-
pressure gauges show the same value immedi-
ately after the air conditioner is switched OFF.
If both gauges show the same value immediate-
ly, it can be assumed that the gasket or the valve
inside the compressor is damaged.
4. Stop the engine.
5. Check the shaft seal and others for leakage.
6. Inspect the drive plate pulley magnetic clutch for
signs of oil.
7. Check the clearance between the drive plate and
pulley. (Refer to page 16—21.)
If any of the above checks reveal faults, repair the
compressor or magnetic clutch.

REMOVAL OF COMPRESSOR
1. Perform the Oil Return Operation. (See below.)
2. Disconnect the battery ground cable.
3. Disconnect the clutch lead wire from the wiring
harness.
4. Discharge the refrigerant from the refrigeration
system.
5. Disconnect the two flexible hoses. Plug the open
fittings immediately to keep moisture out of the
system.
6. Loosen the drive belt.
7. Remove the compressor mounting bolts and the
compressor.

Oil Return Operation
1. If the refrigerant level is low, charge the system to
the specified amount.
2. Run the engine and air conditioner at idle and at
maximum cooling for at least 20 minutes.
