(1) Engine Body

Compression Pressure
1. Operate the engine until it is warmed up.
2. Stop the engine.
3. Remove the air cleaner, the muffler and all injection nozzles.
4. Set a compression tester (Code No. 07909-30208) with the
adaptor (Adaptor H, code No. 07909-31231) to the nozzle hole.
5. After making sure that the stop lever is set at the stop position
(non-injection), operate the engine with the starter and measure
the compression pressure.
6. Repeat steps 4 and 5 for each cylinder.
7. If the measurement is below the allowable limit, apply a small
amount of oil to the cylinder wall through the glow plug hole (or
nozzle hole) and measure the compression pressure again.
8. If the compression pressure is still less than the allowable limit,
check the top clearance, valve clearance and cylinder head.
9. 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.
• Variances in cylinder compression values should be under
10 %.
