CHECK OIL CLEARANCE BETWEEN VANE PUMP SHAFT AND BUSHING OF FRONT HOUSING AND REAR HOUSING (a) Using a micrometer and caliper gauge, measure the oil clearance. Standard clearance: 0.020 to 0.077 mm (0.0008 to 0.00303 in.) for front housing and shaft 0.020 to 0.077 mm (0.0008 to 0.00303 in.) for Rear housing and shaft Maximum clearance:
0.070 mm (0.0028 in.) for front housing and shaft 0.080 mm (0.0032 in.) for rear housing and shaft If the clearance is greater than the maximum, replace a new vane pump assembly. 2. INSPECT VANE PUMP ROTOR AND VANE PLATES (a) Using a micrometer, measure the height, thickness and length of the 10 plates. Minimum thickness: 1.405 mm (0.0553 in.) If the result is less than the minimum, replace the vane pump assembly. (b) Using a feeler gauge, measure the clearance between the rotor groove and plate. Maximum clearance: 0.03 mm (0.0012 in.) If the clearance is greater than the maximum, replace a new vane pump assembly. 3.
INSPECT FLOW CONTROL VALVE (a) Coat the valve with power steering fluid and check that it falls smoothly into the valve hole by its own weight. cardi
