HOSE AS 2080129 - Caterpillar

Problem: The response of one implement is too slow.
Probable Cause
The lever linkage is restricted or the travel is restricted.
The valve spool that is installed in the control valve is incorrect for the implement.
The signal check valve in the signal network is functioning incorrectly. Refer to the Testing and Adjusting, "Pump Control Valve (Hydaulic, Steering) - Test and Adjust" section in this manual.
The implement control valve has failed.
The implement relief valve is set too low.
The signal relief valve is set too low.Steering System
Problem: The steering wheel does not turn the correct number of turns.
Probable Cause
The steering metering pump is leaking internally.
The steering cylinders are leaking or the cylinders have incorrect parts.
An incorrect steering metering pump is installed on the machine.Problem: The steering does not work but the implements do work.
Probable Cause
The hydraulic and steering pump is not receiving a signal pressure from the steering system. Refer to the Testing and Adjusting, "Pump Control Valve (Hydaulic, Steering) - Test and Adjust" section in this manual.
The steering priority valve is malfunctioning. The pressure from the hydraulic and steering pump is blocked to the steering circuit.
There is blockage or damage to the steering circuit or components.Problem: When the steering wheel is steered against the stop, the steering wheel does not stop.
Probable Cause
The steering relief valve is set too high. This allows the relief valve to remain open. Refer to the Testing and Adjusting, "Relief Valve (Steering) - Test and Adjust" section in this manual.
The relief valve in the steering metering pump is set too low.
The steering metering pump has failed. This allows the wheel to continuously turn.
The steering cylinder has failed or the steering cylinder is leaking.
The port is blocked on the steering metering pump or the steering metering pump has a loose connection. This allows air to enter the steering system.Problem: When the steering wheel is released, the steering wheel oscillates more than three times.
Probable Cause
The steering metering pump has failed.
An incorrect steering metering pump has been installed on the machine.
The steering system relief valve is set too high.Problem: The steering wheel has a tendency to stick when the steering wheel is against the stop.
Probable Cause
The steering metering pump has failed and the steering metering pump has trapped pressure in the steering system.
An incorrect steering metering pump has been installed on the machine.Problem: The steering wheel kicks back, when the steering wheel is steered against the stop.
Probable Cause
Air is in the steering cylinders and air is in the steering system. Refer to the Testing and Adjusting, "Steering System - Purge" section in this manual.
The check valve is missing or the check valve is not working. This check valve is in the steering metering pump at the hydraulic pump pressure port.Problem: When an implement is used, you can feel hard spots in the steering.
Probable Cause
The signal resolver in the combination valve has been installed incorrectly after assembly.
Nitrogen precharge is lost in the steering accumulator (If equipped). Refer to the Testing and Adjusting, "Accumulator (Steering) - Test and Charge" section in this manual.Problem:
