OIL PUMP

• Measure the clearance with feeler gauge.
- Clearance between oil pump outer rotor and oil pump body (posi-

tion “1”)

- Tip clearance between oil pump inner rotor and oil pump outer

rotor (position “2”)

• Measure the clearance with feeler gauge and straightedge.
- Side clearance between oil pump inner rotor and oil pump body

(position “3”)

- Side clearance between oil pump outer rotor and oil pump body

(position “4”)

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

OIL PUMP BODY INNER DIAMETER

- Measure the inner diameter of oil pump body with inside microme-

ter. (Position “5”)

OIL PUMP INNER ROTOR OUTER DIAMETER

- Measure the outer diameter of protruded portion of oil pump inner

rotor with micrometer. (Position “6”)

OIL PUMP INNER ROTOR TO OIL PUMP BODY CLEARANCE

- (Clearance) = (Oil pump body inner diameter) – (Oil pump inner rotor outer diameter)

• 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 the calculated value is out of the standard, replace oil pump

assembly.

CAUTION:

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

weight.

PRECAUTIONS

Precaution for Liquid Gasket

INFOID:0000000001325824

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.

Apply liquid gasket to the liquid gasket application surface.
Use Genuine RTV Silicone Sealant or equivalent. Refer to 

GI-44

.

• Within five minutes of liquid gasket application, install the mating component.
• If liquid gasket protrudes, wipe it off immediately.
• Do not retighten mounting bolts or nuts after the installation.
• After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.
