4. Checking and adjusting

4.1 Checking compression pressure
of cylinder
NOTE
• Check the compression pressure with the
specified valve clearance.
• Always use a fully charged battery for you do
this test.
• Variances in cylinder compression values must
be less than 10%.
Tools required
• Compression tester
• Injector adapter
1. Warm-up the engine.
2. Remove the air cleaner and muffler.
3. Remove the glow lead and glow plugs.
4. Disconnect the injector connectors.
5. Set a compression tester (1) with the compression
tester adapter (2) to the glow plug hole.

6. Crank the engine with the starter to operate the
engine approx. 200 to 300 min
7. Measure a maximum value of the compression
pressure.

4.2 Adjusting valve clearance

IMPORTANT
• You must check and adjust the valve clearance
when the engine is cold.
Tools required
• Feeler gauge
1. Remove the air cleaner and muffler.
2. Remove the cylinder head cover.
3. Align the [1TC] mark (2) line on the flywheel and
projection on the housing.
