Separating Engine from Clutch Housing
1. Hoist the engine by the hoist and chain.
2. Remove the engine mounting screws and nuts, and separate the
engine from the clutch housing.
(When reassembling)
• Apply molybdenum disulphide (Three Bond 1901 or equivalent)
to the splines of clutch disc boss.
• Apply liquid gasket (Three Bond 1141, 1211 or equivalent) to joint
face of the engine and clutch housing.

(1) Checking and Adjusting
Compression Pressure
1. After warming up the engine, stop it and remove the air cleaner,
the muffler and all nozzle holders.
2. Install a compression tester (Code No. 07909-30204) for diesel
engines to nozzle holder hole.
3. After making sure that the speed control lever is set at the stop
position (Non-injection), run the engine at 200 to 300 min
-1
(rpm)
with the 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 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 %.
