Oil Pump
OIL PUMPCOMPONENTS:
DISASSEMBLY
1. REMOVE FRONT OIL PUMP BODY O-RING
(a) Remove the front oil pump O-ring from the oil pump.
2. REMOVE STATOR SHAFT ASSEMBLY
(a) Using "Torx" socket wrench T30, remove the 10 "Torx" screws.
3. REMOVE FRONT OIL PUMP DRIVE GEAR
(a) Remove the front oil pump drive gear from the oil pump body.
4. REMOVE FRONT OIL PUMP DRIVEN GEAR
(a) Remove the front oil pump driven gear from the oil pump body.
5. REMOVE FRONT OIL PUMP OIL SEAL
(a) Using SST, remove the front oil pump oil seal from the oil pump body.
SST 09308-00010
6. REMOVE CLUTCH DRUM OIL SEAL RING
(a) Using a screwdriver, remove the 2 clutch drum oil seal rings from the stator shaft assembly.
INSPECTION
1. INSPECT STATOR SHAFT ASSEMBLY
(a) Using a dial indicator, measure the inside diameter of the stator shaft bushings.
Standard inside diameter: 21.500 to 21.526 mm (0.84646 to 0.84748 in.)
Maximum inside diameter: 21.526 mm (0.84748 in.)
If the inside diameter is greater than the maximum, replace the stator shaft.
(b) Install the input shaft assembly onto the stator shaft assembly and check that the input shaft assembly turns smoothly.
NOTICE: Replace the stator assembly with a new one if it moves roughly or makes unusual noise. Inspect the input shaft's contact surface with the bearing when replacing, and replace the input shaft with a new one if any damage or discoloration is found.
2. INSPECT OIL PUMP GEAR CLEARANCE
(a) Measure the clearance between the tips of the driven gear teeth and the drive gear teeth.
Standard tip clearance: 0.07 to 0.15 mm (0.0028 to 0.0059 in.)
Maximum tip clearance: 0.15 mm (0.0059 in.)
If the tip clearance is greater than the maximum, replace the oil pump body sub-assembly.
(b) Push the driven gear to one side of the body. Using a feeler gauge, measure the clearance.
Standard body clearance: 0.10 to 0.15 mm (0.0039 to 0.0059 in.)
Maximum body clearance: 0.15 mm (0.0059 in.)
If the body clearance is greater than the maximum, replace the oil pump body sub-assembly.
(c) Using a steel straight edge and feeler gauge, measure the side clearance of both gears.
Standard side clearance: 0.02 to 0.05 mm (0.0008 to 0.0020 in.)
Maximum side clearance: 0.05 mm (0.0020 in.)
If the side clearance is greater than the maximum, replace the drive gear, driven gear or pump body.

3. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY
(a) Using a dial indicator, measure the inside diameter of the oil pump body bushing.
Standard inside diameter: 38.113 to 38.138 mm (1.50050 to 1.50149 in.)
Maximum inside diameter: 38.138 mm (1.50149 in.)
If the inside diameter is greater than the maximum, replace the oil pump body sub-assembly.
REASSEMBLY
1. INSTALL CLUTCH DRUM OIL SEAL RING
(a) Coat 2 new clutch drum oil seal rings with ATF, and install them onto the stator shaft.
2. INSTALL FRONT OIL PUMP OIL SEAL
(a) Using SST, install the front oil pump oil seal into the oil pump body.
SST 09950-60010 (09951-00550), 09950-70010 (09951-07100)
Oil seal drive in depth: -0.15 to 0.15 mm (-0.006 to 0.006 in.)
3. INSTALL FRONT OIL PUMP DRIVEN GEAR
(a) Coat the front oil pump driven gear with ATF, and install it into 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 into the oil pump body with the marked side facing upward.
5. INSTALL STATOR SHAFT ASSEMBLY
(a) Using "Torx" socket wrench T30, install the stator shaft assembly with 10 "Torx" screws.
Torque: 9.8 N*m (100 kgf*cm, 7 ft.*lbf)
6. INSPECT OIL PUMP ASSEMBLY
(a) Turn the drive gear with 2 screwdrivers and make sure it rotates smoothly.
NOTICE: Do not damage the oil seal lip.
7. INSTALL FRONT OIL PUMP BODY O-RING
(a) Coat a new front oil pump body O-ring with ATF, and install it onto the oil pump.
