1. After warming up the engine, stop it and remove the air cleaner,
the muffler and all nozzle holders / all glow plugs.
2. Install a compression tester for diesel engines to nozzle holder
hole / glow plug hole.
3. After making sure that the stop lever is set at the stop position
(Non-injection), run the engine at 200 to 300 min
starter.
4. Read the maximum pressure. Measure the pressure more than
twice.
5. If the measurement is below the allowable limit, apply a small
amount of oil to the cylinder wall through the nozzle hole / the
glow plug hole and measure the compression pressure again.
6. If the compression pressure increase after applying oil. check the
cylinder wall and piston rings.
7. If the compression pressure is still less than the allowable limit,
check the top clearance, valve and cylinder head.
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 %.
