Diesel engine exhaust contains products of combustion which may cause personal injury. Always start and operate the engine in a well ventilated area, and, if in an enclosed area, vent the exhaust to the outside. |
|
|
Personal injury can result from rotating and moving parts. Stay clear of all rotating and moving parts. Never attempt adjustments while the machine is moving or the engine is running unless otherwise specified. The machine must be parked on a level surface and the engine stopped. Attach a "Do Not Operate" or similar warning tag to the start switch and controls before servicing, repairing, or making adjustments to the machine. |
|
|
Personal injury or death can result from sudden machine movement. Sudden movement of the machine can cause injury to persons on or near the machine. To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine. |
|
|
Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. |

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. 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 Tools and Shop Products Guide", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose of all fluids according to local regulations and mandates. |

Illustration 12 g06228885 - Remove plug (21) and drain oil from filter canister (20). Catch the oil in a suitable container. Dispose of the oil in a suitable container. Dispose of the oil according to local regulations and mandates.
- Use a 1 1/4 inch socket or box end wrench to remove filter canister (20).
- Check the hydraulic filter element for foreign materials.
- Bronze-colored particles indicate pump or motor piston slipper failure.
- Shiny steel particles indicate pump failure or motor piston failure.
- Rubber particles indicate a seal failure or a hose failure
Note: If any of these particles are found in a hydraulic filter element, all components of the hydraulic oil system must be cleaned. Do not use any damaged parts. Any damaged parts must be removed, and new parts must be installed.
- Place a new hydraulic filter element in filter canister (20).
Note: In the next step, use a torque wrench with socket or a box end wrench only. Do not use an air wrench, an open-end wrench, or an adjustable wrench.
- Install filter canister (20) on the filter base. Tighten the filter canister to the toque given in the "Specifications" section.
- Install plug (21).
- Release the door prop, close right compartment door (17), and secure latch (16).
