INSPECTION
NOTICE:
When using a vise, do not overtighten it.
1. CHECK 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: 0.007 mm (0.0028 in.)
If it is more than 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: 8.6 mm (0.339 in.)
Minimum thickness: 1.397 mm (0.05500 in.)
Minimum length: 14.991 mm (0.59020 in.)
(b) Using a feeler gauge, measure the clearance between
the rotor groove and plate.
Maximum clearance: 0.035 mm (0.00138 in.)
If it is more than 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
HINT:
There are 5 vane plate lengths with the following rotor and cam
ring marks:
