1. INSPECT VANE PUMP SHAFT AND BUSHING IN VANE PUMP FRONT HOUSING
(a)
Using a micrometer, measure the outer diameter of the vane pump shaft with pulley [a].
(b) Using vernier calipers, measure the inner diameter of the vane pump front housing bushing [b].
(c)
Calculate the oil clearance. Oil clearance = Inner diameter of the bushing [b] - Outer diameter of the shaft [a].
Maximum oil clearance: 0.07 mm (0.0028 in.)
If the oil clearance exceeds the maximum, replace the vane pump assembly.
2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATE CLEARANCE
(a)
Using a micrometer, measure the thickness of the vane pump plates.
Standard thickness: 1.405 to 1.411 mm (0.05531 to 0.05555 in.)
If the thickness is not within the specified range, replace the vane pump assembly.
(b) Using a feeler gauge, measure the clearance between the side face of the vane pump rotor groove and the vane pump plates.
Maximum clearance: 0.03 mm (0.0012 in.)
If the clearance exceeds the maximum, replace the vane pump assembly.
