INSPECTION
1. INSPECT VANE PUMP SHAFT AND BUSH IN VANE PUMP FRONT HOUSING
(a)
Using a micrometer, measure the outer diameter [a] of the vane pump shaft.
(b) Using a vernier caliper, measure the inner diameter [b] of the vane pump front housing bush.

Calculate the oil clearance.
Oil clearance = Inner diameter of the bush [b] - Outer diameter of the shaft [a]
Maximum oil clearance: 0.07 mm (0.00276 inch)
If the oil clearance exceeds the maximum, replace the vane pump assembly.
2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATE
