SHOE 9W4465 - Caterpillar

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, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Park the machine on a smooth, level surface. Park the machine away from working machines and personnel. Lower the work tool to the ground.
Allow only one operator on the machine. Keep all personnel away from the machine or in the view of the operator.
Engage the parking brake.

Place the steering frame lock into the LOCKED position.
Warm the hydraulic oil to a temperature between 54 °C (130 °F) and 82 °C (180 °F).Note: When you increase the temperature of the hydraulic oil, do not hold the control lever for more than ten seconds.
Turn the engine start switch to the OFF position and remove the key.
Move the control levers several times through the full range of travelwith the key in the ON position. This should relieve the pressure in the hydraulic system.
Place the bucket on the ground or a stand in order to relieve pressure from the ride control system.
Remove the appropriate guards.
Ensure that any hose assembly or any component is clean before removal from the machine or the component is disassembled.Procedure
When you are defining a problem in any of the hydraulic systems, the following procedure should be followed:. When possible, talk to the operator of the machine. Ask about the symptoms of the problem: machine performance, noises, smells and frequency of the problem. Perform a visual inspection of the machine. Look at the following items:
Check the display of the monitoring system for the following machine conditions: alert indicators, warnings and service codes.
Be aware of the work environment. An extreme work environment can greatly affect the symptoms of a machine.
Check the hydraulic oil level in the sight gauge.
Look for air in the hydraulic tank oil immediately after the engine is stopped. Use a clear container to obtain a sample of the oil. Look for air bubbles in the oil in the container.
Remove the hydraulic oil filter and cut the filter open with a filter cutter. Look for particles in the filter elements. A magnet will separate the ferrous particles such as iron and steel from the nonferrous particles such as brass, aluminum, and rubber.
Check all oil lines and all connections for damage and for leaks.
Inspect all of the hydraulic cylinders for damage and for leaks.
Inspect all of the control linkages for components that are bent, broken, or damaged.If the visual inspection does not identify the problem, perform the mechanical system tests. If the mechanical system tests do not identify the problem, perform the electrical system tests.For additional help in resolving a problem, refer to Troubleshooting Manual, RENR8999, "Machine Systems".
