Do not allow unauthorized personnel on the engine or around the engine when the engine is serviced. Engine exhaust contains products of combustion which may be harmful to your health. Always start the engine and operate the engine in a well ventilated area. If the engine is in an enclosed area, vent the engine exhaust to the outside.Cautiously remove the following parts:Note: To help prevent spraying or splashing of pressurized fluids, hold a rag over the part that is being removed.
Filler caps
Grease fittings
Pressure taps
Breathers
Drain plugsUse caution when cover plates are removed. Gradually loosen but do not remove the last two bolts or nuts that are located at opposite ends of the cover plate or the device. Before removing the last two bolts or nuts, pry the cover loose in order to relieve any spring pressure or other pressure.
Wear a hard hat, protective glasses, and other protective equipment, as required.
Do not attempt any repairs that are not understood. Use the proper tools. Replace any equipment that is damaged or repair the equipment.
When work is performed around an engine that is operating, wear protective devices for ears in order to help prevent damage to hearing.
Do not wear loose clothing or jewelry that can snag on controls or on other parts of the engine.
Ensure that all protective guards and all covers are secured in place on the engine.
Never put maintenance fluids into glass containers. Glass containers can break.
Use all cleaning solutions with care.
Report all necessary repairs.Unless other instructions are provided, perform the maintenance under the following conditions:
The engine is stopped. Ensure that the engine cannot be started.
The protective locks or the controls are in the applied position.
Disconnect the batteries when maintenance is performed or when the electrical system is serviced. Disconnect the battery ground leads. Tape the leads in order to help prevent sparks.
For initial start-up of a new engine or for starting an engine that has been serviced, make provisions to stop the engine if an overspeed occurs. This may be accomplished by shutting off the fuel supply and/or the air supply to the engine.
Start the engine with the operator controls. Never short across the starting motor terminals or the batteries. This could bypass the engine neutral start system and/or the electrical system could be damaged.Pressurized Air and Water
Pressurized air and/or water can cause debris and/or hot water to be blown out. This could result in personal injury.When pressurized air and/or pressurized water is used for cleaning, wear protective clothing, protective shoes, and eye protection. Eye protection includes goggles or a protective face shield. The maximum air pressure for cleaning purposes must be reduced to 205 kPa (30 psi) when the air nozzle is deadheaded and used with effective chip guarding (if applicable) and personal protective equipment. The maximum water pressure for cleaning purposes must be below 275 kPa (40 psi). Always wear eye protection for cleaning the cooling system.Fluid Penetration
Always use a board or cardboard when the engine components are checked for leaks. Leaking fluid that is under pressure can cause serious injury or possible death. This includes leaks that are the size of a pin hole.If fluid is injected into the skin, seek treatment immediately. Seek treatment from a doctor that is familiar with this type of injury.Containing Fluid Spillage
Care must be used in order to ensure that the fluids are contained during the inspection, the maintenance, the testing, the adjusting, and the repair of the engine. Prepare to collect the fluid with suitable containers before any compartment is opened or before any component is disassembled. Refer to Catalog, NENG2500, "Caterpillar Dealer Service Tool Catalog" for the following items:
Tools that are suitable for collecting fluids and equipment that is suitable for collecting fluidsObey all local regulations for the disposal of liquids.Asbestos Information
Illustration 2 g00702022
Caterpillar equipment and replacement parts that are shipped from Caterpillar are asbestos free. Caterpillar recommends the use of only genuine Caterpillar replacement parts. Use the following guidelines when you handle any replacement parts that contain asbestos or when you handle asbestos debris.Use caution. Avoid inhaling dust that might be generated when you handle components that contain asbestos fibers. Inhaling this dust can be hazardous to your health. The components that may contain asbestos fibers are brake pads, brake bands, lining material, clutch plates, and some gaskets. The asbestos that is used in these components is usually bound in a resin or sealed in some way. Normal handling is not hazardous unless airborne dust that contains asbestos is generated.If dust that may contain asbestos is present, there are several guidelines that should be followed:
Never use compressed air for cleaning.
Avoid brushing materials that contain asbestos.
Avoid grinding materials that contain asbestos.
Use a wet method in order to clean up asbestos materials.
A vacuum cleaner that is equipped with a high efficiency particulate air filter (HEPA) can also be used.
Use exhaust ventilation on permanent machining jobs.
Wear an approved respirator if there is no other way to control the dust.
Comply with applicable rules and regulations for the work place. In the United States, use Occupational Safety and Health Administration (OSHA) requirements. These OSHA requirements can be found in "29 CFR 1910.1001".
Obey environmental regulations for the disposal of asbestos.
Stay away from areas that might have asbestos particles in the air.Lines, Tubes, and Hoses
Do not bend or strike high pressure lines. Do not install lines, tubes, or hoses that are damaged.Repair any fuel lines, oil lines, tubes, or hoses that are loose or damaged. Leaks can cause fires.Inspect all lines, tubes and hoses carefully. Do not use bare hands to check for leaks. Always use a board or cardboard for checking engine components for leaks. Tighten all connections to the recommended torque.Check for the following conditions:
End fittings that are damaged or leaking
Outer covering that is chafed or cut
Wire that is exposed in reinforced hose
Outer covering that is ballooning locally
Flexible part of the hose that is kinked or crushed
Armoring that is embedded in the outer coveringEnsure that all of the clamps, the guards, and the heat shields are installed correctly. This will help to
