6.

Remove snap ring using external snap ring pliers.

Inspection

Clutch disc
If contact surface shows signs of damage due to excessive heat,
replace clutch disc and pulley.
Pulley
Check appearance of pulley assembly. If contact surface of pulley
shows signs of excessive grooving, replace clutch disc and pulley.
Contact surfaces of pulley assembly should be cleaned with a suit-
able solvent before reinstallation.
Coil
Check coil for loose connection or cracked insulation.

INSTALLATION

1.

Install field coil.
Be sure to align the coil’s pin with hole in compressor’s front
head.

2.

Install field coil harness clip using a screwdriver.

3.

Install pulley assembly using pulley installer (SST) and a hand
press, and then install snap ring using snap ring pliers.

4.

Install clutch disc on drive shaft, together with original shim(s).
Press clutch disc down by hand.

5.

Using holder to prevent clutch disc rotation.

After tightening bolt, make sure pulley rotates smoothly.

6.

Check clearance around entire periphery of clutch disc.

If specified clearance is not obtained, replace adjusting spacer
and readjust.

Break-in Operation

When replacing compressor clutch assembly, always carry out break-in operation. This is done by engaging
and disengaging clutch about thirty-times. Break-in operation raises level of transmitted torque.

Removal and Installation of Low-pressure Flexible Hose

NJS0004G

REMOVAL

1.

Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.

2.

Remove engine cover, using power tools. Refer to 

EM-18, "INTAKE MANIFOLD COLLECTOR"

 .

3.

Remove air cleaner assembly, air hose and air duct. Refer to 

EM-16, "AIR CLEANER AND AIR DUCT"

 .

4.

Remove mounting bolt from low-pressure flexible hose bracket.

5.

Disconnect one-touch joint between low-pressure flexible hose
and low-pressure pipe 1.

a.

Set a disconnector (SST: 9253089916) on A/C piping.

b.

Slide a disconnector toward vehicle front until it clicks.

c.

Slide A/C piping toward vehicle front and disconnect it.

CAUTION:

Cap or wrap the joint of low-pressure flexible hose and low-
pressure pipe 1 with suitable material such as vinyl tape to
avoid the entry of air. 

6.

Remove mounting nut, and then remove low-pressure flexible
hose.

CAUTION:

Cap or wrap the joint of compressor and low-pressure flexi-
ble hose with suitable material such as vinyl tape to avoid
the entry of air.

INSTALLATION

Installation is basically the reverse order of removal.

CAUTION:

●

Replace O-rings of low-pressure flexible hose with new ones, and then apply compressor oil to it
when installing it.

●

Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.

●

Insert piping securely until a click is heard.

●

After piping connection is completed, pull male-side piping by hand to make sure that connection
does not come loose.

●

When recharging refrigerant, check for leaks.

NJS0004H

REMOVAL

1.

Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.

2.

Remove engine cover, using power tools. Refer to 

EM-18, "INTAKE MANIFOLD COLLECTOR"

 .

3.

Remove air cleaner assembly, air hose and air duct. Refer to 

EM-16, "AIR CLEANER AND AIR DUCT"

 .

4.

Remove mounting bolt from high-pressure flexible hose bracket.
