Disassembly

1. Remove bearing race.

2. Remove four seal rings.

3. Loosen six mounting bolts evenly in pattern shown and remove oil pump cover from oil pump housing.

Do not use a punch to mark outer and inner rotors.

4. Mark outer and inner rotors as shown, and separate them from oil pump housing.

5. Remove plug then remove washer, spring and fluid pressure bypass valve.

Inspection

Oil pump housing, outer rotor, inner rotor

1. Install outer rotor and inner rotor.

2. Measure clearance between end of oil pump housing and outer rotor and inner rotor at no less than four

places along their circumferences.

Clearance - Standard : 0.00079~0.0157 in (0.02~0.04 mm)
Maximum : 0.0020 in (0.05 mm)

3. If not as specified, replace oil pump assembly.

4. Measure clearance between oil pump boss and inner rotor in at least four places and calculate average

value.

Inner diameter - Standard : 0.00157~0.00453 in (0.04~0.115 mm)
Maximum : 0.0049 in (0.125 mm)

5. If not within specification, replace oil pump as an assembly.

Minimum : 0.550 in (13.98 mm)

2. If not as specified, replace oil pump as an assembly.

Reassembly

1. Install fluid pressure by pass valve spring into oil pump housing, and verity that fluid pressure by pass valve

moves smoothly.

2. Install a new washer and plug.

Tightening torque : 24~33.6 lb-in (32~47 N·m, 3.2~4.8 kg-m)
