DISASSEMBLY SERVICE POINT



<<A>> SELF-LOCKING NUT REMOVAL



Use the special tools to remove the self-locking nut.

  • Special spanner (MB991367)
  • Pin (MB991386)

<<B>> ROTOR REMOVAL



caution
  • Be sure to use the guide (MB992625) 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 (MB992625) and the side bearing puller (MB990810) as shown.

ASSEMBLY SERVICE POINTS



>>A<< A/C COMPRESSOR COIL INSTALLATION



Install the A/C compressor coil while aligning the pin hole of A/C compressor itself with the protrusion of A/C compressor coil

>>B<< 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 (MB992626) and guide (MB992625).
note Insert the rotor in a direction perpendicular to the A/C compressor.

>>C<< SNAP RING INSTALLATION



Use the snap ring plier and Install the snap ring so that the taper faces the outside.

>>D<< SELF-LOCKING NUT INSTALLATION


Use the special tool as during removal to secure the armature and tighten the self-locking nut.

>>E<< AIR GAP ADJUSTMENT



Check that the air gap of clutch satisfies the standard value. If not within the standard value, use shims to adjust it.
Standard value: 0.25 - 0.50 mm
