(along with the O-ring )
9. Start the engine, warm it up for several min-
utes, and then turn it off.
10.Check:
• Engine
(for engine oil leaks)

MEASURING THE ENGINE OIL PRESSURE
1. Stand the vehicle on a level surface.
TIP
• Place the vehicle on the suitable stand.
• Make sure that the vehicle is upright.
2. Check:
• Engine oil level
Below the minimum level mark “a” → Add the
recommended engine oil to the proper level.
3. Start the engine, warm it up for several min-
utes, and then turn it off.
NOTICE
ECA13410
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.
4. Remove:
• Main gallery bolt “1”
WARNING
EWA12980
The engine, muffler and engine oil are ex-
tremely hot.
5. Install:
• Oil pressure gauge “1”
• Adapter “2”
6. Measure:
• Engine oil pressure
(at the following conditions)
Out of specification → Check.
7. Install:
• Main gallery bolt
• O-ring
