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 oil seal lip.
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 clearance.
Standard body clearance: 0.10 to 0.17 mm (0.0039 to 0.0067 inch)
Side clearance: 0.02 to 0.05 mm (0.001 to 0.002 inch)
Maximum body clearance: 0.17 mm (0.0067 inch)
If the body clearance is greater than the maximum, replace the oil pump body subassembly.
(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 subassembly.
(d) Using a straight edge and feeler gauge, measure the side clearance of both gears.
Drive gear thickness: mm (inch):
Driven gear thickness: mm (inch):
3. INSPECT FRONT OIL PUMP AND GEAR BODY SUBASSEMBLY
(a) Using a dial indicator, measure the inside diameter of the oil pump body bushing.
Standard inside diameter: 38.113 to 38.138 mm (1.50051 to 1.50149 inch)
Maximum inside diameter: 38.188 mm (1.50346 inch)
If the inside diameter is greater than the maximum, replace the oil pump body subassembly.
4. INSPECT STATOR SHAFT ASSEMBLY
(a) Using a dial indicator, measure the inside diameter of the stator shaft.
Standard inside diameter: 21.500 to 21.526 mm (0.84646 to 0.84748 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, install a new oil seal to the oil pump body.
SST 09350-32014 (09351-32140)
HINT: The seal end should be flush 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:
^ Install the O-ring carefully not to have a twist or a pinching.
^ Apply enough ATF to the O-ring prior to 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 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 the bolt holes in the stator shaft assembly with those in the front oil pump and gear body subassembly.
(b) Using a torx socket (T30), 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 clutch drum oil seal rings with ATF.
(b) Install the 2 clutch drum oil seal rings.
NOTICE: Do not expand the ring ends excessively.
