INSPECTION
1. INSPECT OIL PUMP ASSEMBLY
(a) Turn the drive gear with 2 screwdrivers and make sure that it rotates smoothly.
NOTICE: Be careful not to damage the lip of the oil seal.
2. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY
(a) Push the driven gear to one side of the body.
(b) Using a feeler gauge, measure the body clearance between the driven gear and oil pump body.
Standard body clearance: 0.10 to 0.17 mm (0.0039 to 0.0067 inch)
Maximum body clearance: 0.17 mm (0.0067 inch)
If the body clearance is greater than the maximum, replace the oil pump body sub-assembly.
(c) Using a feeler gauge, measure the tip clearance between the driven gear teeth and drive gear teeth.
Standard tip clearance: 0.07 to 0.15 mm (0.0028 to 0.0059 inch)
Maximum tip clearance: 0.15 mm (0.0059 inch)
If the tip clearance is greater than the maximum, replace the oil pump body.
(d) Using a straightedge and feeler gauge, measure the side clearance of both gears.
Standard side clearance: 0.02 to 0.05 mm (0.0008 to 0.0020 inch)
Maximum side clearance: 0.05 mm (0.0020 inch)
Standard drive gear thickness:
Standard driven gear thickness:
3. INSPECT FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY
(a) Using a caliper gauge, measure the inside diameter of the oil pump body bushing.
Standard inside diameter: 38.113 to 38.138 mm (1.5005 to 1.5015 inch)
Maximum inside diameter: 38.188 mm (1.5035 inch)
If the inside diameter is greater than the maximum, replace the oil pump body sub-assembly.
4. INSPECT STATOR SHAFT ASSEMBLY
(a) Using a caliper gauge, measure the inside diameter of the stator shaft.
Standard inside diameter: 21.500 to 21.526 mm (0.8465 to 0.8475 inch)
Maximum inside diameter: 21.57 mm (0.8492 inch)
If the inside diameter is greater than the maximum, replace the stator shaft.
REASSEMBLY
1. INSTALL FRONT OIL PUMP OIL SEAL
(a) Using SST and a hammer, tap in a new oil seal to the oil pump body.
SST 09350-32014 (09351-32140)
HINT: The seal end should be flat 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:
^ Make sure that the O-ring is not twisted or pinched.
^ Apply enough ATF to the O-ring before installation.
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 facing upward.
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 facing upward.
5. INSTALL STATOR SHAFT ASSEMBLY
(a) Set the stator shaft and align it with each bolt hole.
(b) Using a T30 "TORX" socket, install the 11 bolts.
Torque: 9.8 Nm (100 kgf-cm, 87 inch lbs.)
6. INSTALL CLUTCH DRUM OIL SEAL RING
(a) Coat 2 new oil seal rings with ATF.
(b) Install 2 new clutch drum oil seal rings.
NOTICE: Do not expand the ring ends excessively.
