Magnet Clutch Operating Check

S6JB0B7206036

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

S6JB0B7206037

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: 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.)

7) Install compressor to vehicle referring to

“Compressor Assembly Removal and Installation”.

Relief Valve On-Vehicle Inspection

S6JB0B7206038

Using special tool (A), check if there is refrigerant
leakage.
If there is refrigerant leakage, replace compressor body.
