Compressor Assembly Removal and
Installation

S5JB0B7206035

Removal

1) Run engine at idle with A/C ON for 10 minutes.
2) Disconnect negative (–) cable at battery.
3) Recover refrigerant from the A/C system using

recovery and recycling equipment referring to
“Recovery” in “Operation Procedure for Charging A/
C with Refrigerant”.

NOTE
The amount of compressor oil at removed
must be measured and the same amount
must be poured when installing the
compressor.

4) Disconnect MAF sensor coupler, and then remove

air cleaner assembly.

5) Remove A/C compressor drive belt referring to

“Accessory Drive Belt and Idler Pulley Removal and
Installation in Section 1J”.

6) Disconnect magnet clutch connector.
7) Disconnect suction hose and discharge hose from

compressor.

NOTE
Cap open fitting immediately to keep
moisture out of system.

8) Remove compressor from its mount.

Installation

CAUTION

!

Be sure to use HFC-134a (R-134a)
compressor oil.

Reverse removal procedure noting the following
instructions.
• If compressor is replaced, pour new compressor oil

referring to “Precautions on Replenishing Compressor
Oil”.

• Evacuate and charge system referring to “Evacuation”

and “Charge” in “Operation Procedure for Charging A/
C with Refrigerant”.

• Install drive belt referring to “Accessory Drive Belt and

Idler Pulley Removal and Installation in Section 1J”.

Magnet Clutch Operating Check

S5JB0B7206039

Check the following items.
If any detects are found, repair or replace magnet clutch
assembly.
• Inspect armature plate and rotor for signs of oil.
• Check clutch bearings for noise and grease leakage.
• Using an ohmmeter (3), measure resistance of stator

coil between clutch lead wire (1) and body ground (2).
If measured resistance is not within tolerance, replace
coil.

Magnet Clutch Removal and Installation

S5JB0B7206041

Removal

1) Remove compressor from vehicle referring to

“Compressor Assembly Removal and Installation”.

2) Fix armature plate (1) with special tool (A) and

remove armature plate bolt.

Special tool
(A): 09991–06310

NOTE
Do not reuse armature plate bolt.

3) Remove armature plate.
4) Remove shim(s) from shaft.
5) Using special tool (A), remove snap ring (1).

Special tool
(A): 09900–06107

6) Remove magnet clutch pulley (1) with puller (2).

NOTE
Be careful not to damage pulley.

7) Remove snap ring (1) using special tool (B), and

then remove magnet clutch coil (1).

Special tool
(A): 09900–06107

Installation

1) Install magnet clutch coil (3).

NOTE
Protrusion (1) on underside of magnet clutch
coil and hole (2) on compressor body
assembly must match to stop movement of
magnet clutch coil and to locate lead wire
correctly.

2) Install new snap ring (1) using special tool (A).

Special tool
(B): 09900–06107

3) Install magnet clutch pulley.

a) Set magnet clutch horizontally over clutch

installation boss.

b) Place special tool (B) onto magnet clutch

bearing. Ensure that edge rests only inner rase
of bearing.

Special tool
(B): 09951–15510

c) Install new snap ring (1) using special tool (A).

Special tool
(A): 09900–06107

4) Install armature plate (1).
5) Using special tool (A), tighten new armature plate

bolt (2) to specified torque.

Tightening torque
Armature plate bolt (a): 21 N·m (2.1 kgf-m, 15.5
lb-ft)

Special tool
(A): 09991–06310

6) Adjust clearance between armature plate (1) and

magnet clutch pulley by putting shim(s) on
compressor shaft. To measure the clearance,
perform the following steps.
a) Put compressor in a vise.
b) Set dial gauge on magnet clutch plate, and then

adjust its pointer at 0.

c) Connect battery positive terminal (+) to magnet

clutch coil lead wire.

d) Connect battery negative terminal (–) to

compressor body assembly. (At this point,
armature plate and magnet clutch pulley (2) are
kept in contact.)

e) Disconnect battery negative terminal (–) to

compressor body assembly. (At this point,
armature plate and magnet clutch pulley (2) are
not in contact.)

f) Read stroke of armature plate from dial gauge by

performing Step d) and e) repeatedly. (Stroke of
armature plate is clearance between armature
plate and magnet clutch pulley (2).)

Standard clearance between armature plate and
magnet clutch
“a”: 0.3 – 0.6 mm (0.012 – 0.024 in.)
