Fig. 38: Removing Vane Pump Housing Oil Seal 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. Fig. 39: Measuring Outer Diameter Of Vane Pump Shaft b. Using a vernier caliper, measure the inner diameter [b] of the vane pump front housing bush. c. 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 in.) If the oil clearance exceeds the maximum, replace the vane pump assembly. 2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATE a. Using a micrometer, measure the thickness of the vane pump plates.
