INSPECTION

1. INSPECT FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY





(a) Turn the drive gear with 2 screwdrivers and make sure that it rotates smoothly.
NOTE:
Be careful not to damage the oil seal lip.

2. INSPECT CLEARANCE OF FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY





(a) Push the driven gear to one side of the body.
(b) Using a feeler gauge, measure the clearance.
Standard clearance:
0.08 to 0.15 mm (0.0031 to 0.0059 in.)
Maximum clearance:
0.15 mm (0.0059 in.)
If the clearance is greater than the maximum, replace the oil pump body sub-assembly.





(c) Using a straight edge and feeler gauge, measure the side clearance of both gears.
Standard side clearance:
0.025 to 0.04 mm (0.0010 to 0.0016 in.)





Maximum side clearance:
0.04 mm (0.0016 in.)





3. INSPECT FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY





(a) Using a dial indicator, measure the inside diameter of the oil pump body bushing.
Standard inside diameter:
43.113 to 43.138 mm (1.6974 to 1.6983 in.)
Maximum inside diameter:
43.188 mm (1.7003 in.)
If the inside diameter is greater than the maximum, replace the oil pump body sub-assembly.
4. INSPECT STATOR SHAFT ASSEMBLY





(a) Using a dial indicator, measure the inside diameter of the oil pump body bushing.
Standard inside diameter:
22.500 to 22.526 mm (0.8858 to 0.8868 in.)
Maximum inside diameter:
22.570 mm (0.8886 in.)
If the inside diameter is greater than the maximum, replace the oil pump body sub-assembly.
