Suzuki DR650SE - Oil Pressure Check

PERIODIC MAINTENANCE 2-18
OIL PRESSURE CHECK
Check periodically the oil pressure in the engine to judge roughly the condition of the moving parts.
OIL PRESSURE SPECIFICATION
Above 30 kPa (0.3 kg/cm2, 4.3 psi)
Below 70 kPa (0.7 kg/cm2, 10 psi)
at 3 000 r/min., Oil temp. at 60°C (140°F)
If the oil pressure is lower or higher than the specification, the following causes may be considered.
LOW OIL PRESSURE
* Oil leakage from the oil passage way
* Damaged O-ring
* Defective oil pump
* Combination of above items
HIGH OIL PRESSURE
* Used a engine oil which is too high viscosity
* Clogged oil passage way
* Combination of above items
OIL PRESSURE TEST PROCEDURE
Check the oil pressure in the following manner.
• Remove the oil pressure inspection plug.
• Install the oil pressure gauge in the position shown in the
figure.
• Warm up the engine as follows:
Summer 10 min. at 2 000 r/min.
Winter 20 min. at 2 000 r/min.
• After warming up, increase the engine speed to 3 000
r/min. (with the engine tachometer), and read the oil pres-
sure gauge.
