Illustration 1 g00297292
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.Note: The difference in times between forward and reverse should not exceed 0.5 seconds for HIGH travel speed and 1.0 seconds for LOW travel speed.
Place the travel speed control switch in the LOW position and repeat Steps 8 through 9.
