INSPECTION
1. CHECK OIL CLEARANCE BETWEEN VANE PUMP
SHAFT AND BUSHING
Using a micrometer and caliper gauge, measure the oil clear-
ance. Standard clearance:
0.03 − 0.05 mm (0.0012 − 0.0020 in.)
Maximum clearance: 0.07 mm (0.0028 in.)
If it is more than maximum, replace the front housing and vane
pump shaft.
2. INSPECT V ANE PUMP ROTOR AND 10 VANE PLATES
(a) Using a micrometer, measure the height, thickness and length of the plate.
Minimum height: 8.6 mm (0.339 in.)
Minimum thickness: 1.397 mm (0.0550 in.)
Minimum length: 14.991 mm (0.5902 in.)
(b) Using a feeler gauge, measure the clearance between the rotor groove and plate.
Maximum clearance: 0.033 mm (0.0013 in.)
If more than maximum, replace the plate and/or rotor with one
having the mark equivalent to the mark stamped on the cam
ring. Inscribed mark
Vane pump rotor: 1, 2, or None
Cam ring: 2, 3, or 4
