CAUTION

• Be sure to use the guide (MB992623) when 

the side bearing puller (MB990810) is used to 
prevent the damage of A/C compressor.

• If the threaded shaft of side bearing puller 

(MB990810) is turned than necessary, the 
rotor may be distorted. Therefore, turn the 
threaded shaft lightly only by hand without 
using any tools.

Rotor can be removed by hand, but if it is difficult to 
remove it, use the guide (MB992623) and the side 
bearing puller (MB990810) as shown.

REASSEMBLY SERVICE POINTS

>>A<< A/C COMPRESSOR HIGH PRES-
SURE RELIEF VALVE INSTALLATION

CAUTION

Be careful not to damage the O-ring when install-
ing the high-pressure relief valve. Apply the 
specified refrigerating machine oil the high-pres-
sure relief valve mounting hole before installa-
tion

Check that O-ring is installed to the high-pressure 
relief and use the adjust torque wrench to install the 
high-pressure relief valve to the main body of the 
compressor.

>>C<< ROTOR INSTALLATION

CAUTION

If the outer wheel side of rotor is pushed, an 
abnormal noise can be generated because the 
inside of rotor is damaged, therefore, always 
push the inner wheel side.

Install the rotor while pushing the inner wheel side 
slowly using the pusher (MB992624) and guide 
(MB992623).

NOTE: Insert the rotor in a direction perpendicular to 
the A/C compressor.

Tapered part

Using snap ring pliers, fit the snap ring so that the 
snap ring’s tapered part is on the outside.

>>E<< SELF-LOCKING NUT 
INSTALLATION

AC709546AC

MB991386

MB991367

Using a special tool, as when removing the nut, 
secure the armature and tighten the self-locking nut.

>>F<< AIR GAP ADJUSTMENT

AC707121

Thickness gauge

AE

Check whether or not the air gap of the clutch is 
within the standard value.

Standard value:

 0.25 

− 0.45 mm

NOTE: If there is a deviation of the air gap from the 
standard value, make the necessary adjustment by 
adjusting the number of shims.
