Assembly

1. Install the oil pump outer gear and oil pump inner gear to the pump housing. If reusing the old gears, install so that the mating marks that were made during disassembly are aligned.




2. Measure the side clearance between the oil pump outer gear and oil pump inner gear. If the clearance is greater than the standard value, replace the oil pump assembly.

Standard value:
Side clearance between oil pump outer gear and oil pump inner gear 0.020 - 0.046 mm (0.00079 - 0.00181 in.)




3. Measure the clearance between the oil pump outer gear and the pump housing pocket. If the clearance is greater than the standard value, replace oil pump assembly.

Standard value
Clearance between oil pump outer gear and pocket 0.045 - 0.141 mm (0.00171 - 0.00555 in.)




4. Assemble the pump housing and reaction shaft support, and then install them with the six bolts.




5. Place the tour seal rings onto the reaction shaft support.




6. Install the oil pump O-ring.
