Engine Lubrication: Testing and Inspection

NOTE: Prior-to checking oil pressure, check the followings.
- Oil level in oil pan.
If oil level is low, add oil up to Full level hole on oil level gauge.
- Oil quality.
If oil is discolored, or deteriorated, change it.
- Oil leaks.
If leak is found, repair it.





1. Remove engine under cover of right side from body.
2. Remove oil pressure switch from cylinder block.





3. Install special tool (Oil pressure gauge) to vacated threaded hole.

Special Tool, or equivalent:
(A): 09915-77310
(B): 09915-78211

4. Start engine and warm it up to normal operating temperature.
5. After warming up, raise engine speed to 4,000 r/min and measure oil pressure.

Oil pressure specifications: 330 - 430 kPa (3.3 - 4.3 kg/cm,, 46.9 - 61.1 psi) at 4,000 r/mm (rpm)

6. After checking oil pressure, stop engine and remove oil pressure gauge.





7. Before reinstalling oil pressure switch, be sure to wrap its screw threads with a sealing tape and tighten switch to specified torque.

NOTE: If sealing tape edge is bulged out from screw threads of switch, cut it off.

Tightening Torque (a): 14 Nm (10.5 ft. lbs.)





8. After installing oil pressure switch, start engine and check oil pressure switch for oil leakage.
9. Install right side of engine under cover to body.
