Information:
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Note: This machine is equipped with a pilot hydraulic system.This section provides probable causes to a known problem. Since there may be several probable causes, specific inspections or specific instrument tests may be recommended. These inspections and tests will help to identify the cause that is most probable.The following is a list of some pertinent terms and the definitions of those terms.Collapse - The sudden drop of a cylinder during normal operationDrift - Slow motion of the implement cylinders while the blade control lever is in the HOLD position.Droop - Hydraulic cylinders move initially in the direction that is opposite of the direction that is commanded by the operator. The cylinders then move in the correct direction.Possible problem list for the hydraulic systemThe implement pump makes noise and the cylinder rods do not move evenly. There are also air bubbles in the oil.Probable causes
The viscosity of the oil is incorrect.
The main relief valve opens at low oil pressure.
There is a loose connection of the suction line on the inlet side of the implement pump.
The implement pump has too much wear. The oil temperature is too high.Probable causes
The machine is being operated above the intended capacity or in ambient temperatures that are too high for the machine's design.
The viscosity of the oil is incorrect.
The setting of one or both of the implement relief valves is too low.
The implement pump has too much wear.
There is a restriction in an hydraulic oil passage.
There is a leak in one or more circuits.
The hydraulic oil level is low.
The hydraulic oil is contaminated.
The air flow through the hydraulic oil cooler is too low.
The oil flow through the hydraulic oil cooler is too low.
There is air in the hydraulic oil. Note: A problem with air in the hydraulic oil must be corrected before the hydraulic system will operate at normal temperatures. There are two conditions that cause air to be in the hydraulic oil:
Return oil is flowing into the hydraulic oil tank above the level of oil that is in the tank.
There are leaks in the oil suction line between the implement pump and the hydraulic oil tank.
The hydraulic oil temperature sensor is faulty. The output of the implement pump is low.Probable causes
The oil level is low.
The viscosity of the oil is incorrect.
The implement pump has too much wear.
The setting of one or both of the implement relief valves is too low.
There is a restriction in the supply line.
The setting of the pilot relief valve is too low. The oil pressure is low.Probable causes
One or both of the implement relief valves opens at low oil
