ENGINE TESTING
Checking oil pressure
1. Remove the bolt from the hole in the crankcase and fit a
pressure gauge with 0 to 10 kg/cm² full scale (fig.95)
2. Start the engine, accelerate to 3000 rpm and wait for the oil to
reach a temperature of 70 to 80°C.
3.The pressure reading must be between 2.5 and 4 kg/cm².
4. Reduce engine speed to minimum; the pressure should not fall
below 1 ÷ 1.5 Kg/cm² with oil temperature of 80°C.
Checking for oil leaks
1. Remove the exhaust gas collection pipe from the inlet manifold
and close the connection with a plug (fig.96).
2. Start the engine and let it run for a few minutes. The high
pressure generated in the crankcase will show up any oil leaks.
3. Reconnect the exhaust gas collection pipe to the inlet manifold.
Dyno testing of engine
After you have placed the engine on the brake (fig.97) perform the
following:
1. Check the oil level (fig.98).
2. Start the engine and let it idle.
3. Check the oil pressure on the pressure gauge (fig.95)
4. Run in engine before testing it at full power.
Speed adjustment (fig.94)
When the engine is hot set idle speed at 1000 rpm and maximum
no-load speed at:
3150 rpm
for engines MD350
3750 rpm
for engines MD351
