19204 1 Mercury GASKET (SEE DESIGN II DRAWING)

General Hazard Information
Attach a DO NOT OPERATE or similar warning tag to the start switch or controls before performing maintenance or repairing the engine. These tags, SEHS7332, are available from your Caterpillar dealer. When appropriate, attach the tags at the engine and at each operator's position. Disconnect starting controls when appropriate. Do not allow unauthorized personnel on, around or in the engine unit when it is being serviced.Engine exhaust contains products of combustion which may be harmful to your health. Always start and operate the engine in a well ventilated area and, if in an enclosed area, vent the exhaust to the outside.Use caution when removing filler cap, grease fittings, pressure taps, breathers or drain plugs. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure.* Wear a hard hat, protective glasses, hearing protection and other protective equipment as required by job conditions.* Do not wear loose clothing or jewelry that can catch on controls or other parts of the engine.* Make certain all protective guards and covers are secured in place.* Use all cleaning solutions with care.* Never put maintenance fluids into glass containers since glass containers can break.* Report all needed repairs.* Stop the engine.* Ensure the protective locks or controls are in the applied position.* Disconnect the batteries whenever performing any maintenance or before servicing the electrical system. If the engine has an electric starting motor, disconnect and tape the battery ground leads to prevent accidental starting.* Do not attempt any repairs or adjustments to the engine or driven equipment while it is running.* Do not attempt repairs you do not understand. Use proper tools; replace or repair broken or damaged equipment.* When starting an engine after repairs have been made to the fuel system or governor, make provisions for shutting off the engine's fuel supply and inlet air supply (to stop the engine), in case there is an overspeed on start-up. * Start the engine only from the operator's station. Never short across the starting motor terminals or the batteries as this could bypass the engine neutral start system as well as damage the electrical system.Pressure Air and Water
Pressure air can cause personal injury. When using pressure air for cleaning, wear a protective face shield, protective clothing and protective shoes.The maximum air pressure must be below 205 kPa (30 psi) and maximum water pressure must be below 275 kPa (40 psi) for cleaning purposes.Wear eye protection at all times when cleaning the cooling system. Pressurized water could cause debris and/or hot water to be blown and result in personal injury.Fluid Penetration
Always use a board or cardboard when checking for a leak. Escaping fluid under pressure, even a pin hole size leak, can penetrate body tissue, causing serious injury or possible death.If fluid is injected into your skin, it must be treated by a doctor familiar with this type of injury immediately.Fluid Spillage Containment
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the engine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to NENG2500, Tools And Shop Products Guide, for tools and supplies suitable to collect and contain fluids used in Caterpillar engines. Dispose of fluids according to local regulations and mandates.Asbestos Information
This Caterpillar product and replacement parts shipped from the factory are asbestos free. Caterpillar recommends the use of only genuine Caterpillar replacement parts. If any replacement parts containing asbestos fibers are used, the following guidelines should be used in handling these parts and asbestos debris.Asbestos used in components is usually bound in a resin or sealed in some way. Normal handling is not hazardous as long as airborne dust which contains asbestos is not generated.Caution should be used to avoid breathing dust that may be generated when handling components containing asbestos fibers. If this dust is inhaled, it can be hazardous to your health.If dust, which may contain asbestos is present, there are several guidelines that should be followed.* Never use compressed air for cleaning* Avoid brushing or grinding of asbestos containing materials* For clean up, use wet methods or a vacuum equipped with a high efficiency particulate air (HEPA) filter* 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 (for example in the USA, OSHA requirements as set forth in 29 CFR 1910.1001)* Follow environmental rules and regulations for disposal of asbestos* Avoid areas where airborne asbestos particles may be presentLines, Tubes and Hoses
Do not bend or strike high pressure lines. Do not install bent or damaged lines, tubes or hoses.Repair any loose or damaged fuel and oil lines, tubes and hoses. Leaks can cause fires.Inspect all lines, tubes and hoses carefully. Do not use your bare hands to check for leaks. Tighten all connections to the recommended torque. Check for the following:* End fittings damaged, leaking or displaced* Outer covering chafed or cut and wire reinforcing exposed* Outer covering ballooning locally* Evidence of kinking or crushing of the flexible part of the hose* Armoring embedded in the outer coverMake sure that all clamps, guards and heat shields are installed correctly to prevent vibration, rubbing against other parts and excessive heat during operation.Burn Prevention
Do not touch any part of an operating engine. Allow the engine to cool before any repair or maintenance is performed on the engine.Relieve all pressure in air, oil, fuel or cooling systems before any lines, fittings or related items are disconnected or removed.Coolant
Use caution when removing filler cap, grease fittings, pressure taps, breathers or drain plugs. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure.To prevent personal injury, do not step up on engine to remove the filler cap, if applicable. Use an adequate ladder.At operating temperature, the engine coolant is hot and under pressure. The
