Reverse Travel Test on Level Ground (Optional Test)
Note: When the procedure for "Travel Test On Level Ground" cannot be performed, this test may be used as a substitute.
Start the engine.
Position the machine on level ground.
Put a mark on a shoe of each track.
Raise a track off the ground.
Move the engine speed dial to high idle.
Increase the hydraulic oil temperature to 55 5°C (130 10°F).
Place the travel speed control switch in HIGH position.
Press the travel pedal for the raised track to the 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.

Travel motor (1) Minimum displacement screw (2) Maximum displacement screwFrom the factory, an M12X50 setscrew is used for the maximum displacement screw. The M12X50 setscrew acts as a plug. The setscrew is not long enough to adjust the displacement. You will need a M12X70 setscrew ( 9X-8482 Setscrew ) in order to adjust the maximum displacement. An M12X80 setscrew is used for the minimum displacement screw. This screw will adjust the minimum displacement.Refer to Table 10 for a list of the part numbers and the lengths of the available displacement screws.
