cartridge and the oil pump for damage or
leakage. Refer to "OIL PAN AND OIL
PUMP" in chapter 5.

MEASURING THE ENGINE OIL PRESSURE
1. Check:
• engine oil level
Below the minimum level mark → Add the
recommended engine oil to the proper level.
2. Remove:
• side cowlings
3. Start the engine, warm it up for several min-
utes, and then turn it off.
CAUTION:
@
When the engine is cold, the engine oil will
have a higher viscosity, causing the engine
oil pressure to increase. Therefore, be sure
to measure the engine oil pressure after
warming up the engine.
