2-42 PERIODIC MAINTENANCE
OIL PRESSURE CHECK
Check the oil pressure periodically. This will give a good indication of the condition of the moving parts.
 Oil pressure
25 kPa (0.25 kgf/cm², 3.6 psi) at 6 000 r/min, oil temp. at 50 °C (122 °F)
Low or high oil pressure can indicate any of the following conditions:
LOW OIL PRESSURE
* Clogged oil filter
* Oil leakage from the oil passage
* Damaged oil seal
* Defective oil pump
* Combination of the above items
HIGH OIL PRESSURE
* Engine oil viscosity is too high
* Clogged oil passage
* Combination of the above items
