Measure the clearance with the feeler gauge and the straight-
edge.
Side clearance between inner rotor and oil pump housing (posi-
tion 3)
Side clearance between outer rotor and oil pump housing (posi-
tion 4)

Calculate the clearance between inner rotor and oil pump housing as follows.
–Measure the outer diameter of protruded portion of inner rotor
(position 5).
–Measure the inner diameter of oil pump housing with the inside
micrometer (position 6).
(Clearance) = (Inner diameter of oil pump housing) – (Outer
diameter of inner rotor)
 If measured/calculated values are out of the standard, replace
oil pump assembly.
Regulator Valve Clearance
(Clearance) = (Valve hole diameter) – (Regulator valve outer diame-
ter)

If out of the standard, replace oil pump assembly.
CAUTION:

Coat regulator valve with new engine oil.

Make sure that it falls smoothly into valve hole by its own
weight.Standard : 0.050 - 0.090 mm (0.0020 - 0.0035 in)
