OIL PUMP
●Calculate the clearance between inner rotor and oil pump hous-
ing as follows.
1. Measure the outer diameter of protruded portion of inner rotor
(Position 5)
2. Measure the inner diameter of oil pump housing with inside
micrometer (Position 6)
(Clearance) = (Inner diameter of oil pump housing) – (Outer
diameter of inner rotor)
Regulator Valve
1. Visually inspect components for wear and damage.
2. Check oil pressure regulator valve sliding surface and valve spring.
3. Coat regulator valve with engine oil. Check that it falls smoothly into the valve hole by its own weight.
If damaged, replace regulator valve set or oil pump housing.
4. Check regulator valve to oil pump housing clearance.
CAUTION:
Coat regulator valve with engine oil.
ASSEMBLY
●Assemble in the reverse order of disassembly.
●Install the inner rotor and outer rotor with the punched marks on
the oil pump cover side.
●After warming up the engine, check for oil leakage and oil level.

Precautions For Liquid GasketEBS00MRX
REMOVAL OF LIQUID GASKET
●After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.
●In areas where the cutter is difficult to use, use a plastic hammer
to lightly tap the areas where the liquid gasket is applied.
CAUTION:
If for some unavoidable reason a tool such as a flat-blade
screwdriver is used, be careful not to damage the mating
surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
●Remove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts and bolt
holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach the liquid gasket to the tube presser.
Use Genuine Liquid Gasket or equivalent.
4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
●If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
●As for the bolt holes, normally apply the liquid gasket inside
the holes. If specified, it should be applied outside the holes.
Make sure to read the instruction in this manual.
●Within five minutes of liquid gasket application, install the mat-
ing component.
●If the liquid gasket protrudes, wipe it off immediately.
●Do not retighten after the installation.
●After 30 minutes or more have passed from the installation, fill
the engine oil and engine coolant.
CAUTION:
If there are instructions in this manual, observe them.
