Removal and Installation

EBS00SJF

●

Remove oil pump housing. Refer to

EM-68, "PRIMARY TIMING CHAIN"

.

Disassembly and Assembly

EBS00SJG

CAUTION:

Before installation, apply new engine oil to the parts as instructed in the figure.

DISASSEMBLY

1.

Remove oil pump cover.

2.

Remove inner rotor and outer rotor from oil pump housing.

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 housing (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 housing (posi-
tion 3)

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

●

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 cover.

4.

Check regulator valve to oil pump cover clearance.

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.

Removal and Installation

EBS00SJH

CAUTION:

●

Be careful not to get burned when the engine and engine oil are hot.

●

When removing, prepare a shop cloth to absorb any oil leakage or spillage.

●

Completely wipe off any oil that abhere to the engine and the vehicle.

REMOVAL

1.

Remove front RH wheel and engine side cover.

2.

Remove the exhaust front tube.

3.

Drain coolant by removing cylinder block drain plug and disconnecting radiator lower hose.

INSPECTION
Oil Cooler

Check oil cooler for cracks and clogging by blowing through coolant inlet. If necessary, replace oil cooler
assembly.

INSTALLATION

Installation is in reverse order of removal.

●

Confirm that no foreign objects are adhering to the installation
planes of the oil cooler and block.

●

Tighten the connecting bolt after aligning the stopper on the cyl-
inder block side with protrusion of the oil cooler.
