Use oil pressure gauge kit 9995270 .

Adapter 9995273 , hose 9995272 and gauge 9995271 . Connect these items to the hole on the cylinder block for the oil pressure sensor.

Start the engine. Read off the oil pressure at different engine speeds (RPM).

Minimum oil pressure at:

13.3 r/s (800 r/min)	0.10 MPa	-
14.2 r/s (850 r/min)	0.10 MPa	-
66.7 r/s (4000 r/min) minimum	0.35 MPa	-
66.7 r/s (4000 r/min) maximum	0.70 MPa	-

NOTE: The relief valve begins to open at 0.5 MPa.

Remove the tools.

Use a new gasket when installing the oil pressure sensor.

Tighten to 25 Nm .
