Steering Time CheckTest Preparation
Refer to Testing and Adjusting, "Machine Preparation for Troubleshooting".
Move steering frame lock to the STORED position.
Start the engine. Operate the engine at high idle. Continuously stall the RACK BACK function while simultaneously raising the lift arms at full speed. When the lift arms are almost raised, cycle the tilt cylinder almost to the FULL DUMP position. Then move the tilt cylinders to the full RACK BACK position. Continuously stall the RACK BACK function and simultaneously lower the lift arms back to the ground level position. Without stalling the RACK BACK function, cycle the lift function to raise the lift arms fully. Then lower the lift arms in order to allow the pump to operate at low-pressure briefly and circulate oil through the system. Repeat this process in order to increase the temperature of the oil to normal operating temperature.
Park the machine on a surface that is hard, dry, and level.
Place the transmission selector lever in the NEUTRAL position.Note: The hydraulic controls should also be in the NEUTRAL position. The parking brake should be disengaged.Test Procedure
Articulate the machine to the left or to the right until the machine stops articulating.
Run the engine at high idle.Note: Start to measure steering time when you start to turn the steering wheel. Measure steering time until the machine stops articulating.
Articulate the machine in the opposite direction until the machine stops articulating. Steering time should be 2.9 0.5 seconds.
If the steering time is not within specifications, check the neutral pilot pressure. See the following reference.ReferenceFor the correct procedure to check the neutral pilot pressure, refer to the Service Manual module for Testing and Adjusting, "Pilot Valve (Command Control Steering) Supply Pressure - Test and Adjust" for the machine that is being serviced.ReferenceFor the correct procedure to check the margin pressure for the piston pump, refer to the Service Manual module for Testing and Adjusting, "Piston Pump (Steering) Margin Pressure - Test and Adjust" for the machine that is being serviced.
