2.3 Measuring end play of rotor and pump case
Measure the end play of the rotor and the pump case. If
measured value exceeds the limit, replace the oil pump with
new one.

2.4 Measuring clearance between outor rotor
and pump case
Measure the clearance between the outer rotor and the pump
case. If measured value exceeds the limit, replace the oil
pump with new one.

case
2.5 Reassembling oil pump
(1)
Install the pump case cover to the pump case with
aligning the match marks (indentations). If the match
marks are not aligned, the oil pump will not suck up oil.
(2)
Install the oil strainer, and tighten the bolt.
2.6 Inspecting relief valve
(1)
Check the relief valve and its valve seat for contact
condition. Check the spring for fatigue and damage. If
it is faulty, replace the relief valve with new one.
(2)
Measure the valve opening pressure (oil pressure when
the engine is running at rated speed) of the relief valve.
If the measured value is out of the standard, remove the
plug and make an adjustment by increasing and
decreasing the shim thickness.
