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.
2.
INSPECT VANE PUMP ROTOR AND VANE PUMP
PLATE
(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:
11.993 mm (0.4722 in.)
(b) Using a feeler gauge, measure the clearance
between a side face of the vane pump rotor groove
and vane plate.
Maximum clearance:
0.025 mm (0.0010 in.)
If it is greater than the maximum, replace the vane
pump assembly.
