ASSEMBLY SERVICE POINTS

.

>>A<< FIELD CORE ATTACHMENT

Line up the pin hole on the compressor unit with the field core 
projection and attach.

.

>>B<< SNAP RING INSTALLATION

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

.

>>C<< SELF-LOCKING NUT INSTALLATION

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

.

>>D<< AIR GAP ADJUSTMENT

Check whether or not the air gap of the clutch is within the stan-
dard value.

Standard value:

 0.3 

− 0.5 mm (0.012 − 0.020 inch)

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