REPAIR FOR COMPONENT PARTS





OIL PUMP
DISASSEMBLY





1. Loosen bolts in numerical order and remove oil pump cover.





2. Remove rotor, vane rings and vanes.
- Inscribe a mark on back of rotor for identification of fore-aft direction when reassembling rotor. Then remove rotor.





3. While pushing on cam ring remove pivot pin.
- Be careful not to scratch oil pump housing.





4. While holding cam ring and spring lift out cam ring spring.
- Be careful not to damage oil pump housing.
- Hold cam ring spring to prevent it from jumping.





5. Remove cam ring and cam ring spring from oil pump housing.





6. Remove pivot Pin from control piston and remove control piston assembly.





7. Remove oil seal from oil pump housing.
- Be careful not to scratch oil pump housing.

INSPECTION
Oil pump cover, rotor, vanes, control piston, side seals, cam ring and friction ring





- Check for wear or damage.





Side Clearances
- Measure side clearances between end of oil pump housing and cam ring, rotor, vanes and control piston. Measure in at least four places along their circumferences. Maximum measured values should be within specified positions.
- Before measurement, check that friction rings, 0-ring, control piston side seals and cam ring spring are removed.





Standard clearance (Cam ring, rotor, vanes and control piston): Refer to image.

- If not within standard clearance, replace oil pump assembly except oil pump cover assembly.





Seal Ring Clearance
- Measure clearance between seal ring and ring groove.

Standard clearance: 0.10 - 0.25 mm (0.0039 - 0.0098 inch)
Wear limit: 0.25 mm (0.0098 inch)

- If not within wear limit, replace oil pump cover assembly.

ASSEMBLY





1. Drive oil seal into oil pump housing.
- Apply ATF to outer periphery and lip surface.





2. Install cam ring in oil pump housing by the following steps.
a. Install side seal on control piston.
- Pay attention to its direction - Black surface goes toward control piston.
- Apply petroleum jelly to side seal.
b. Install control piston on oil pump.





c. Install O-ring and friction ring on cam ring.
- Apply petroleum jelly to 0-ring.





d. Assemble cam ring, cam ring spring and spring seat. Install spring by pushing it against pump housing.





e. While pushing on cam ring install pivot pin.





3. Install rotor, vanes and vane rings.
- Pay attention to direction of rotor.





4. Install oil pump housing and oil pump cover.
a. Wrap masking tape around splines of oil pump cover assembly to protect seal. Position oil pump cover assembly in oil pump housing assembly, then remove masking tape.
b. Tighten bolts in a criss-cross pattern.





5. Install new seal rings carefully after packing ring grooves with petroleum jelly. Press rings down into jelly to a close fit.
- Seal rings come in two different diameters. Check fit carefully in each groove.

Small diameter seal ring: No mark
Large diameter seal ring: Yellow mark in area shown by arrow

- Do not spread gap of seal ring excessively while installing. It may deform ring.
