The performance level of the travel motors can be determined with the following procedure.Note: The engine speed and/or the machine configuration that is used during this test can affect the results of this test. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for the engine speed that was used for this test. Refer to Testing and Adjusting, "Operational Checks" for the machine configurations that were used for this test.Note: The relief valve pressure settings must be set to the relief valve pressure specification before performing this operational check. Refer to Testing and Adjusting, "Specifications".Required Tools

(A) Travel distance 20 m (65.6 ft)
(B) Height of heel 0.5 m to 1 m (1.6 ft to 3.3 ft)
Travel distance must be at least 20 m (65.6 ft) long. Travel test ground must be hard and as level as possible.
Draw a 20 m (65.6 ft) straight line on travel test ground as a reference line.Test Procedure
Start the engine.
Place the machine controls at the following settings: Engine speed dial "10" and AEC switch OFF.
Place the hydraulic lockout in the UNLOCKED position.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Position the machine so that one track is parallel with the reference line. Position the machine for the travel test. Refer to Illustration 1.
Place the travel speed control switch in HIGH position.
Move the machine by operating both travel levers at the same time.
Measure the travel time that is required to travel the 20 m (65.6 ft). Measure the time that is required in each direction.
Measure the travel deviation from the reference line.
Place the travel speed control switch on the LOW position and repeat Steps 7 through 9.Adjustment Procedure
Note: Do not increase the speed of the travel motor in the HIGH speed position beyond the factory setting. This operation will increase the speed of the motor and the gear drive beyond the allowable factory specification. Increasing the speed of the travel motor in the HIGH speed position, could result in lower component life, component failure, and/or voided warranty.HIGH Speed

(1) HIGH speed minimum displacement screw
Turn minimum displacement screw (1) to increase or decrease the speed of the travel motor for the HIGH speed position.Note: Turn the displacement screw clockwise to decrease the travel motor speed.Note: Turn the displacement screw counter
