MOUNTING GP-BODY 2273904 - Caterpillar

Probable Causes
Blockages, restrictions, or kinks in hoses, lines or tubes
Oil leaks in hoses, lines or tubes or at fittings
The hydraulic oil is too thick or the type of oil is incorrect.
charge pump becomes too inefficient and cannot produce the required oil flow and pressures
Steering solenoid connectors are not connected properly
The steering pump controls are suspect.
The NEUTRAL setting for the steering pump is improperly adjusted.Recommended Actions
Note: Care must be taken in order to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the machine. You must be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component that contains fluid. Dispose of all fluids according to local regulations.Blockages, Restrictions, Or Kinks In Hoses, Lines Or Tubes
Blockages, kinks, or restrictions in both the supply and return oil lines can prevent oil flow to or from the steering motor and can create unusual noises due to the high pressures involved. The steering motor cannot turn without oil flow to the pump and from the pump. Check for these conditions on all hydraulic oil hoses, lines, and tubes in the steering system.Oil Leaks In Hoses, Lines Or Tubes Or At Fittings
Check for leaks at all fittings and connections of hydraulic oil hoses, lines, and tubes in the system in question. Correct any problems that are found then retest for the symptom(s).Leaks at fittings and connections on the pressure side of pumps are a direct source of oil loss in the system, which can lead to component failure if the low oil levels are not monitored and pumps and motors are starved of oil.Leaks at fittings and connections on the suction side of pumps are a direct source of oil aeration, which can also cause cavitation damage to components and create excess or unusual noise as well.Leaks at fittings and other types of hydraulic line connections can cause loss of oil flow and prevent components from attaining pressures necessary to perform work. Pressure losses generate complaints of weak force such as the blade tilt or the lift force and implements drifting while in the HOLD condition. Flow losses generate complaints of component speed such as the fan speed or the cylinder speed.The Hydraulic Oil Is Too Thick Or The Type Of Oil Is Incorrect.
Ensure that oil is the correct viscosity for the operating conditions. In order to determine the correct oil viscosity, refer to the Operation and Maintenance Manual, SEBU8408, "Lubricant Viscosities and Refill Capacities".Charge Pump Becomes Too Inefficient And Cannot Produce The Required Oil Flow And Pressures
Use a flow meter to test the flow rate of the Steering Charge Pump. Refer to Specifications, Systems Operation & Testing and Adjusting, KENR8558, "Relief Valve (Charge) - Test and Adjust". If the charge pump becomes too inefficient and cannot produce the required oil flow and pressures, steering will be slow to react, turns will not be as sharp, or the machine may not steer at all.Steering Solenoid Connectors Are Not Connected Properly
Ensure that
