INSPECTION
NOTICE:
When using a vise, do not overtighten it.
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 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 plates.
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: 0.035 mm (0.0014 in.)
If it is more than the maximum, replace the plate and/or rotor
with the one having the same mark stamped on the cam ring.
Inscribed mark: 1, 2, 3, 4 or None
