Oil Pump Disassembly and
Inspection
1. Remove the driven rotor (Figure 8-7, (1)).

Figure 8-7
2. Remove the plug, gasket, spring and relief
valve (Figure 8-7, (1)).
3. Inspect the relief valve (Figure 8-8, (1)) by
applying engine oil to the valve and check if it
falls into the valve hole smoothly by its own
weight. If not, replace the relief valve. If needed,
replace the oil pump assembly.

4. Check the drive shaft by turning the gear
(Figure 8-9) and check if the drive shaft turns
smoothly and the bearing has no play. If
needed, replace the oil pump assembly.

5. Check the clearance at the rotor tooth tip.
Measure clearance at the tips of drive and
driven rotors using a feeler gauge
(Figure 8-10). If the measured clearance
exceeds the specified maximum, replace the oil
pump assembly.
Rotor tip tooth clearance:
• Standard: 0.080 to 0.160 mm (0.031 to 6.29 in.)
• Maximum: 0.21 mm (0.008 in.)

6. Check the clearance of the rotor body by
measuring the clearance between the driven
rotor and rotor body using a feeler gauge
(Figure 8-11). If the measured clearance
exceeds the specified maximum, replace the oil
pump assembly.
