INSPECTION
NOTICE:
When using a vise, do not overtighten it.
1. MEASURE OIL CLEARANCE BETWEEN VANE PUMP
SHAFT AND BUSHING
Using a micrometer and a 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 the maximum, replace the front housing and
vane pump shaft.
2. INSPECT VANE PUMP ROTOR AND VANE PLATES
(a) Using a micrometer, measure the height, thickness and
length of the 10 plates.
Minimum height: 8.1 mm (0.319 in.)
Minimum thickness: 1.797 mm (0.0707 in.)
Minimum length: 14.988 mm (0.59008 in.)
(b) Using a feeler gauge, measure the clearance between
the rotor groove and plate.
Maximum clearance: 0.03 mm (0.0012 in.)
If it is more than the maximum, replace the plate and/or rotor
with one having the same mark stamped on the cam ring.
Inscribed mark: 1, 2, 3, 4 or None
