Oil Pump Assembly Disassembly and Reassembly

1)Remove rotor plate (1) by removing rotor plate bolts.

2)Remove outer rotor (1) and inner rotor (2).

3)Remove relief valve (1), relief valve spring (2) and retainer (3) by removing circlip (4).

1)Clean and then dry all disassembled parts.

2)Apply thin coat of engine oil to inner and outer rotors, inside surfaces of timing chain cover and rotor plate.

3)Install outer rotor (1) and inner rotor (2) to timing chain cover.

4)Apply engine oil to oil pump relief valve (1) and oil pump relief spring (2), and install them with relief valve retainer (3) and new circlip (4) to rotor plate.

5)Install rotor plate and tighten rotor plate bolts to specified torque. After installing plate, check that rotors turn smoothly by hand (Torque: 0.3 N·m (0.03 kgf-m, 0.25 lbf-ft) or less).
