Checking the "Stalling" Speed
Checking the stalling speedThis test indicates the general condition of the engine and transmission by checking the maximum engine speed in positions D and R. To check the stalling speed:
1. Ensure that the transmission has reached working temperature, (50° - 80°C). Switch off the A/C and headlights.
2. Put chocks under all 4 wheels.
3. Apply the Handbrake fully.
4. Press the brake pedal hard.
5. Start the engine and move the selector lever to position D.
6. Give full gas and quickly read off the highest engine speed. "Stall" speed will be 2,250 - 2,450 rpm for B205E, B235E/R, B308E and 2,600 - 2,700 rpm for D223L.
Important: Do not run for longer than 5 seconds when testing as the oil temperature can rise above the permitted level. Wait at least 1 minute between tests.
7. Repeat the test with the selector lever in position R. Stalling speed should be the same as above.
