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.

NOTICE: 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.)

Driven gear thickness:








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.

REASSEMBLY





1. INSTALL FRONT OIL PUMP OIL SEAL
(a) Using SST and a hammer, install a new oil seal to the oil pump body.
SST 09350-32014 (09351-32140)

NOTICE: The seal end should be level with the outer edge of the oil pump.

(b) Coat the lip of the oil seal with MP grease.





2. INSTALL FRONT OIL PUMP BODY O-RING
(a) Coat a new O-ring with ATF and install it to the oil pump body.

NOTICE: Ensure that the O-ring is not twisted.





3. INSTALL FRONT OIL PUMP DRIVEN GEAR
(a) Coat the front oil pump driven gear with ATF and install it to the oil pump body with the marked side up.





4. INSTALL FRONT OIL PUMP DRIVE GEAR
(a) Coat the front oil pump drive gear with ATF, and install it to the oil pump body with the marked side up.





5. INSTALL STATOR SHAFT ASSEMBLY
(a) Align each knock pin of the stator shaft with the holes in the oil pump body and install the stator shaft to the oil pump body with the 16 bolts.
(b) Using a "TORX" socket (T30), install the 11 bolts.
Torque: 9.3 N*m (95 kgf*cm, 82 in.*lbf)





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