(1) Compression Pressure
Compression Pressure
1. Run the engine until it is warmed up.
2. Stop the engine and disconnect the
2P
connector from the stop
solenoid in order to inject fuel.
3. Remove the air cleaner, the muffler and all injection nozzle.
4. Set a compression tester (Code No. 07909-30208) with the
adaptor to the nozzle hole.
5. Keep the engine stop lever at "
Stop Position
".
6. While cranking the engine with the starter, measure the
compression pressure.
7. Repeat steps 4 through 6 for each cylinder.
8. If the measurement is below the allowable limit, apply a small
amount of oil to the cylinder wall through the nozzle hole and
measure the compression pressure again.
9. If the compression pressure is still less than the allowable limit,
check the top clearance, valve cylinder.
10. If the compression pressure increases after applying oil, check
the cylinder wall and piston rings.
NOTE
• Check the compression pressure with the specified valve
clearance.
• Always use a fully charged battery for performing this test.
• Variance in cylinder compression values should be under
10 %.
