- Start the engine.
- Position the machine on level ground.
- Increase the hydraulic oil temperature to 55° ± 5°C (131° ± 9°F).
- Raise a track off the ground. Refer to Illustration 1.
- Put a mark on a shoe of the raised track.
- Place the machine controls at the following settings: Engine speed dial "10" and AEC switch OFF.
- Place the travel speed control switch in HIGH position.
- Move the travel lever of the raised track to full travel position.
- Measure the time that is required for the raised track to make three complete revolutions. Measure the time that is required in each direction.
- Place the travel speed control switch in the LOW position and repeat Steps 8 through 9.
