Oil Pump Clearance
Measure the clearance with feeler gauge.
–Clearance between oil pump outer rotor and oil pump body
(position “1”)
–Tip clearance between oil pump inner rotor and oil pump outer
rotor (position “2”)
–If out of the standard, replace inner rotor and outor rotor.
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
micrometer. (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. Standard : 0.114 - 0.260 mm (0.0045 - 0.0102 in)
Standard : Below 0.180 mm (0.0071 in)

Regulator Valve Clearance
(Clearance) = (Regulator valve hole diameter) – (Regulator valve
outer diameter)
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.
ASSEMBLY
Note the following, and assemble in the reverse order of disassembly.
Install oil pump inner rotor with the groove faced to oil pump
cover side.Standard : 0.040 - 0.097 mm (0.0016 - 0.0038 in)

Precautions for Liquid GasketNBS004Q7
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
