2.

Apply engine oil to the oil seal circumference of new oil filter.

3.

Screw oil filter manually until it touches the installation surface,
then tighten it by 2/3 turn. Or tighten to specification.

INSPECTION AFTER INSTALLATION

1.

After warming up engine, check for engine oil leakage.

2.

REMOVAL

1.

Remove front cover.
Refer to 

EM-38, "Removal and Installation"

 . 

2.

Remove oil pump drive spacer.

●

Set bolts in the two bolts holes [M6 x 1.0 mm (0.039 in)] on
the front surface. Using a small puller, remove oil pump drive
spacer from crankshaft.

NOTE:
The dimension between the centers of the two bolt holes is 33
mm (1.30 in).
In the figure, the commercial steering puller is used.

3.

Remove oil pump.

INSTALLATION

1.

Install oil pump.

2.

Install oil pump drive spacer as follows.

a.

When inserting oil pump drive spacer, align the crankshaft key
and the flat face of inner rotor.

●

If they are not aligned, rotate inner rotor by hand.

b.

Make sure that the each part is aligned. Using a tool such as a
plastic hammer, tap lightly until it reaches the end.

3.

Install in the reverse order of removal.

INSPECTION AFTER INSTALLATION

●

Start engine, and check there is no leak of engine oil.

●

Check level of engine oil, and add engine oil. Refer to 

LU-6, "ENGINE OIL"

Disassembly and Assembly

ABS000MF

DISASSEMBLY

1.

Remove oil pump cover.

2.

Remove inner rotor and outer rotor from oil pump body. 

3.

After removing regulator plug, remove regulator spring and regulator valve.

INSPECTION AFTER DISASSEMBLY 
Clearance of Oil Pump Parts

●

Measure clearance with feeler gauge.
Clearance between outer rotor and oil pump body (position 1)

Tip clearance between inner rotor and outer rotor (position 2)

●

Measure clearance with feeler gauge and straightedge.
Side clearance between inner rotor and oil pump body (position
3)

       Side clearance between outer rotor and oil pump body (posi-
tion 
       4)

●

Calculate the clearance between inner rotor and oil pump body
as follows.

–

Measure the outer diameter of protruded portion of inner rotor
(Position 5)

–

Measure the inner diameter of oil pump body with inside
micrometer (Position 6)

•

(Clearance) = (Inner diameter of oil pump body) – (Outer diame-
ter of inner rotor)

●

If out of the standard, replace oil pump assembly.

Standard

: 0.114 - 0.200 mm (0.0045 - 0.0079 in)

Regulator Valve Clearance

(Clearance) = D1 (Valve hole diameter) – D2 (Outer diameter of
valve)

●

If out of the standard, replace oil pump assembly.

CAUTION:

●

Coat regulator valve with engine oil.

●

Check that it falls smoothly into the regulator valve hole by
its own weight.
