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 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)
Standard : 0.030 - 0.190 mm (0.0012 - 0.0075 in)

Precautions for Liquid GasketEBS00MRX
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.

Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt
holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the tube presser (special service
tool).
Use Genuine Liquid Gasket or equivalent.

Within five minutes of liquid gasket application, install the mat-
ing component.

If liquid gasket protrudes, wipe it off immediately.

Do not retighten mounting bolts or nuts after the installation.

Wait 30 minutes or more after installation before refilling
engine oil and engine coolant.
