• If measured/calculated values are out of the standard, replace oil pump assembly.

Regulator Valve Clearance

(Clearance) = (Regulator valve hole diameter) – (Regulator valve
outer diameter)

assembly.

CAUTION:

• Coat regulator valve with engine oil.
• Check that it falls smoothly into valve hole by its own weight.
