1. After warming up the engine, shut it down and remove the air
cleaner, the muffler, breather tube, glow lead and all glow plugs.

glow plug adaptor for 07 series diesel engines (2) to glow plug
hole. (See page G-52.)
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.
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 %.
