Forward Traction Test

NOTE: See Sauer–Sundstrand IHT Service Manual for more information.

Use a 10,000 PSI (700 Bar) gauge.

Specification: 6,200 PSI (428 Bar) maximum

1.Make sure hydraulic oil is at normal operating temper- ature by operating the machine for approximately 10 minutes.

2.Lower cutting unit, engage parking brake and stop the engine.

3.Remove the plug from the forward traction pressure port and install a 10,000 PSI (700 Bar) pressure gauge with extension hose.

4.On 4WD machines, raise the implement and engage the transport switch so the IHT operates with less torque to the wheels. Engage the parking brake, and run the en­ gine at full speed. Slowly push the traction pedal forward and listen for engagement of the easy ride valve. Contin­ ue to push the traction pedal and read the gauge.

NOTE: When you move the traction pedal to create pressure, move it a short distance first and wait for a change in sound before moving the pedal further. The change in sound indicates that the easy ride valve has closed.
