INSPECTION

1.

INSPECT OIL CLEARANCE
(a) Using a micrometer and caliper gauge, measure the 

oil seal clearance.
Standard clearance:

0.021 to 0.043 mm (0.0008 to 0.0017 in.)

Maximum clearance:

0.07 mm (0.0028 in.)

If it is greater than the maximum, replace the vane 
pump assembly.

(a) Using a micrometer, measure the height, thickness 

and length of the vane plates.
Minimum height:

7.6 mm (0.299 in.)

Minimum thickness:

1.405 mm (0.0553 in.)

Minimum length:
