INSPECTION


1. CHECK OIL PUMP BODY BUSH
caution Measure the inside diameter at different places and take an average. If the measurement is greater than the maximum, replace the oil pump body with a new one. When the oil pump body is replaced, inspect the contact surface opposed to the torque converter assembly. If the surface is scratched or discoloured, replace the torque converter assembly with a new one.

Using a dial indicator, measure the inside diameter of the oil pump body bush.
Standard value: 38.113 - 38.138 mm
(For oil pump body bush clearance)

2. CHECK STATOR SHAFT BUSH
caution Measure the inside diameter at different places and take an average. If the measurement is greater than the maximum, replace the stator shaft assembly with a new one. When the stator shaft assembly is replaced, inspect the contact surface opposed to the input shaft sub-assembly. If the surface is scratched or discoloured, replace the input shaft sub-assembly with a new one.

Using a dial indicator, measure the inside diameter of the stator shaft bush.
Standard value: 21.501 - 21.527 mm
(For stator shaft bush clearance)

3. CHECK BODY CLEARANCE
caution If the clearance is greater than the maximum, replace the oil pump body with a new one.

Push the oil pump driven gear to one side of the oil pump body. Using a feeler gauge, measure the clearance.
Standard value: 0.10 - 0.17 mm
(For oil pump driven gear to oil pump body clearance)

4. CHECK BODY CLEARANCE OF BOTH GEARS
caution Measure the tip clearance at different places and take an average. If the measurement is greater than the maximum, replace the oil pump drive gear and the oil pump driven gear with new ones.

Using a feeler gauge, measure the tip clearance between the oil pump drive gear teeth and the oil pump driven gear teeth.
Standard value: 0.07 - 0.15 mm
(Between the oil pump drive gear teeth and the oil pump driven gear teeth)

5. CHECK SIDE CLEARANCE OF BOTH GEARS
caution If the measurement is not within the specified range, replace the oil pump drive gear and the oil pump driven gear with new ones that will allow the side clearance to fall within the specified range. If the side clearance is still not within the specified range, replace the oil pump assembly with a new one.

Using a steel straight edge and feeler gauge, measure the side clearance of both gears.
Standard value: 0.03 - 0.05 mm
(For oil pump gear clearance)
