U660E AUTOMATIC TRANSMISSION / TRANSAXLE: OIL PUMP: INSPECTION

1. INSPECT FRONT OIL PUMP BODY SUB-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 FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY

(a) Push the driven gear to one side of the body.





(b) Using a feeler gauge, measure the clearance.

Standard clearance:

0.08 to 0.15 mm (0.00315 to 0.00590 in.)

Maximum clearance:

0.15 mm (0.00590 in.)

If the clearance is greater than the maximum, replace the oil pump body sub-assembly.

(c) Using a straightedge and feeler gauge, measure the side clearance of both gears.





Standard side clearance:

0.025 to 0.04 mm (0.000984 to 0.00157 in.)

Maximum side clearance:

0.04 mm (0.00157 in.)

3. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY

(a) Using a caliper gauge, measure the inside diameter of the oil pump body bushing.





Standard inside diameter:

43.113 to 43.138 mm (1.6974 to 1.6983 in.)

Maximum inside diameter:

43.188 mm (1.7003 in.)

If the inside diameter is greater than the maximum, replace the front oil pump body sub-assembly.

4. INSPECT STATOR SHAFT ASSEMBLY

(a) Using a caliper gauge, measure the inside diameter of the oil pump body bushing.





Standard inside diameter:

22.500 to 22.526 mm (0.8858 to 0.8868 in.)

Maximum inside diameter:

22.570 mm (0.8886 in.)

If the inside diameter is greater than the maximum, replace the front oil pump body sub-assembly.
