OIL PUMP

COMPONENTS:

DISASSEMBLY





1. REMOVE CLUTCH DRUM OIL SEAL RING
(a) Remove the 2 clutch drum oil seal rings.





2. REMOVE STATOR SHAFT ASSEMBLY
(a) Using a torx socket (T30), remove the 11 bolts and stator shaft.
(b) Keep the gears in assembling order.





3. REMOVE FRONT OIL PUMP DRIVE GEAR
(a) Remove the front oil pump drive gear.





4. REMOVE FRONT OIL PUMP DRIVEN GEAR
(a) Remove the front oil pump driven gear.





5. REMOVE FRONT OIL PUMP BODY O-RING
(a) Using a screwdriver, remove the O-ring.

HINT: Tape the screwdriver before use.





6. REMOVE FRONT OIL PUMP OIL SEAL
(a) Mount oil pump in a soft jaw vise.
(b) Using SST, remove the oil seal from the oil pump body.
SST 09308-00010

INSPECTION





1. INSPECT OIL PUMP ASSEMBLY
(a) Turn the drive gear with 2 screwdrivers and make sure 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 - 0.17 mm (0.0039 - 0.0067 inch)
Side clearance: 0.02 - 0.05 mm (0.001 - 0.02 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 - 0.15 mm (0.0028 - 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.
Standard side clearance: 0.02 - 0.05 mm (0.0008 - 0.0020 inch)
Maximum side clearance: 0.05 mm (0.0020 inch)

Drive gear thickness: mm (inch) (Part 1):

Drive gear thickness: mm (inch) (Part 2):

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 - 38.138 mm (1.50051 - 1.50149 inch)
Maximum inside diameter: 38.138 mm (1.50149 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 - 21.526 mm (0.84646 - 0.84748 inch)
Maximum inside diameter: 21.526 mm (0.84748 inch)
If the indicator diameter is greater than 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 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 the new O-ring with ATF, install it to the oil pump body.

NOTICE: Assemble the O-ring carefully not to have a twist and a pinching. Moreover, apply enough ATF to the O-ring prior to assembling.





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





5. INSTALL STATOR SHAFT ASSEMBLY
(a) Set the stator shaft aligned with each bolt hole.
(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 the 2 new clutch drum oil seal rings with ATF.
(b) Install the 2 new clutch drum oil seal rings.

NOTICE: Do not expand the ring ends excessively.
