PROCEDURE
INSPECT FRONT OIL PUMP ASSEMBLY
Install the oil pump drive shaft sub-assembly to the front oil pump assembly.
Note
To avoid damaging the bush of the front oil pump assembly, install the oil pump drive shaft sub-assembly perpendicularly relative to the front oil pump assembly.
Align the cutout of the oil pump drive shaft sub-assembly and the cutout of the front oil pump drive gear, and install the parts.
Make sure that the oil pump drive shaft sub-assembly rotates smoothly.
If the oil pump drive shaft sub-assembly does not rotate smoothly, inspect the front oil pump drive gear and front oil pump driven gear and front oil pump body.
Remove the oil pump drive shaft sub-assembly from the front oil pump assembly.
Note
To avoid damaging the bush of the front oil pump assembly, remove the oil pump drive shaft sub-assembly perpendicularly relative to the front oil pump assembly.
INSPECT STATOR SHAFT ASSEMBLY
Using a caliper gauge, measure the inside diameter of the bushing of the stator shaft assembly (for torque converter assembly).
| Standard Inside Diameter |
|---|
| 25.201 to 25.227 mm (0.992 to 0.993 in.) |
| Maximum Inside Diameter |
|---|
| 25.227 mm (0.993 in.) |
If the inside diameter is more than the maximum, replace the stator shaft assembly.
Using a caliper gauge, measure the inside diameter of the bushing of the stator shaft assembly (for oil pump drive shaft sub-assembly).
| Standard Inside Diameter |
|---|
| 12.020 to 12.035 mm (0.473 to 0.474 in.) |
| Maximum Inside Diameter |
|---|
| 12.035 mm (0.474 in.) |
If the inside diameter is more than the maximum, replace the stator shaft assembly.
INSPECT FRONT OIL PUMP COVER SUB-ASSEMBLY
Using a caliper gauge, measure the inside diameter of the bushing of the front oil pump cover sub-assembly.
| Standard Inside Diameter |
|---|
| 8.02 to 8.035 mm (0.31575 to 0.31634 in.) |
| Maximum Inside Diameter |
|---|
| 8.035 mm (0.31634 in.) |
If the inside diameter is more than the maximum, replace the front oil pump cover sub-assembly.
INSPECT FRONT OIL PUMP BODY AND GEAR SUB-ASSEMBLY
Using a feeler gauge, measure the body clearance between the front oil pump driven gear and front oil pump body.
| Standard Body Clearance |
|---|
| 0.135 to 0.175 mm (0.00531 to 0.00689 in.) |
| Maximum Body Clearance |
|---|
| 0.175 mm (0.00689 in.) |
If the body clearance is more than the maximum, replace the front oil pump body and front oil pump driven gear.
Using a straightedge and feeler gauge, measure the side clearance of both gears.
| Standard Side Clearance |
|---|
| 0.015 to 0.034 mm (0.000591 to 0.00134 in.) |
| Maximum Side Clearance |
|---|
| 0.034 mm (0.00134 in.) |
If the side clearance is more than the maximum, replace the front oil pump body, front oil pump drive gear, front oil pump driven gear and stator shaft assembly.
