Oil Pump Disassembly

Turn the drive gear with 2 screwdrivers and make sure that it rotates smoothly.

NOTICE:

Be careful not to damage the oil seal lip.

Using a "TORX" wrench (T30), remove the 16 bolts and stator shaft assembly from the oil pump body.

NOTICE:

Keep the gears in the order of installation.

Push the driven gear to one side of the body.

Using a feeler gauge, measure the clearance.

Standard clearance:

0.08 to 0.15 mm (0.0031 to 0.0059 in.)

Maximum clearance:

0.15 mm (0.0059 in.)

Using a straight edge and feeler gauge, measure the side clearance of both gears.

Standard side clearance:

0.025 to 0.04 mm (0.0010 to 0.0016 in.)

Maximum side clearance:

0.04 mm (0.0016 in.)

Drive gear thickness:
