Oil Pump Clearance
Measure clearance with feeler gauge.
Clearance between oil pump outer rotor and oil pump body

Tip clearance between oil pump inner rotor and oil pump outer
rotor (position “2”)
Measure 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.
Measure the inner diameter of oil pump body with inside
micrometer (Position “5”)
Measure the outer diameter of protruded portion of oil pump
inner rotor (Position “6”)
(Clearance) = (Inner diameter of oil pump body) – (Outer diame-
ter of oil pump inner rotor)
Regulator Valve Clearance
(Clearance) = (Regulator valve hole diameter) – (Outer diameter of
regulator valve)
CAUTION:
Coat regulator valve with new engine oil.
Make sure it falls smoothly into the regulator valve hole by
its own weight.Standard : 0.114 - 0.260 mm (0.0045 - 0.0102 in)

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 tube presser [SST: WS39930000
(—)].
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
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.
After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.EMA0622D
