Inspection and Repair

Drive Plate

If the frictional surface shows signs of damage due to
excessive heat, the drive plate and pulley should be
replaced.

Pulley Assembly

Check the appearance of the pulley assembly.  If the
frictional surface of the pulley shows signs of excessive
grooving due to slippage, both the pulley and drive plate
should be replaced.  The frictional surfaces of the pulley
assembly should be cleaned with a suitable solvent
before reinstallation.

Coil

Check coil for loose connector or cracked insulation.

Installation

1. Install field coil.

• Align the located portion (1) of the field coil and

compressor.

871RY00035

• Tighten the mounting screw to the specified

torque.

Torque: 5N·m (0.5kg·m/44 lb in)

2. Connect the lead wire connector with the rubber

hold and tighten the screw.

3. Install pulley assembly by using pulley installer

J-33940-A(2) and drive handle J-8092(1).

871RY00032

4. Install snap ring.

5. Install shim (s).

6. Install the drive plate to the compressor drive shaft

together with the original shim(s)(1).  Press the drive
plate by hand.

7. Install drive plate bolt by using drive plate holder

J-33939 (1) to prevent the drive plate from rotating.

871RX029

• Tighten the drive plate bolt to the specified

torque.

Torque: 13 N·m (1.3kg·m/113 lb in)

• After tightening the drive plate bolt, check to be

sure the pulley rotates smoothly.

• Check to be sure that the clutch clearance is

between 0.3-0.6 mm (0.01-0.02 in.)

871RY00028

EndOFCallout

• If necessary, install adjusting shim(s).

• Adjusting shims are available in the following

thickness.

Thickness

• 0.1 mm (0.0039 in.)

• 0.3 mm (0.0118 in.)

• 0.5 mm (0.0197 in.)

Compressor Oil

Oil Specification

• The HFC-134a system requires a synthetic (PAG)

compressor oil whereas the R-12 system requires a
mineral compressor oil. The two oils must never be
mixed.

• Compressor (PAG) oil varies according to

compressor model. Be sure to use oil specified for
the model of compressor.

• Always use HFC-134a Vane Rotary Type

Compressor Oil (AIPDN Part No.2-90188-301-0)

Handling of Oil

• The oil should be free from moisture, dust, metal

powder, etc.

• Do not mix with other oil.

• The water content in the oil increases when exposed

to the air. After use, seal oil from air immediately.
(HFC-134a Vane Rotary Compressor Oil absorbs
moisture very easily.)

• The compressor oil must be stored in steel

containers, not in plastic containers.

Compressor Oil Check

The oil used to lubricate the compressor is circulating
with the refrigerant.
Whenever replacing any component of the system or a
large amount of gas leakage occurs, add oil to maintain
the original amount of oil.

Oil Capacity

Capacity total in system: 150cc (5.0 fl.oz)

Compressor (Service parts) charging amount:

150 cc (5.0 fl.oz)

Checking and Adjusting Oil Quantity
for Used Compressor

1. Perform oil return operation. Refer to Oil Return

Operation in this section.

2. Discharge and recover refrigerant and remove the

compressor.

3. Drain the compressor oil and measure the extracted

oil with a measuring cylinder.

871RX020

4. If the amount of oil drained is much less than 90 cc

(3.0 fl. oz.), some refrigerant may have leaked out.
Conduct a leak tests   on the connections of each
system, and if necessary, repair or replace faulty
parts.

5. Check the compressor oil contamination. (Refer to

Contamination of Compressor Oil in this section.)

6. Adjust the oil level following the next procedure

below.

7. Install the compressor, then evacuate, charge and

perform the oil return operation.

8. Check system operation.

When it is impossible to preform oil return
operation, the compressor oil should be  checked in
the following order:

1. Discharge and recover refrigerant and remove the

compressor.

2. Drain the compressor oil and measure the extracted

oil with a measuring cylinder.

3. Check the oil for contamination.

4. If more than 90 cc (3.0 fl. oz.) of oil is extracted from

the compressor, supply the same amount of oil to
the compressor to  be installed.

5. If the amount of oil extracted is less than 90 cc (3.0

fl. oz.), recheck the compressor oil in the following
order.

6. Supply 90 cc (3.0 fl. oz.) of oil to the compressor

and install it onto the vehicle.

(Charging Amount)

(Collected Amount)

more than 90cc (3.0 fl.oz)

same as collected  
amount

less than 90 cc (3.0 fl.oz)

90cc (3.0 fl.oz)
