TAPE 5019389 - Caterpillar

Operate the priming pump plunger until the flow of fuel from the fuel line is continuous and free of air bubbles. Push the plunger in and tighten by hand. If the engine does not have a fuel priming pump, crank the engine.Tighten each fuel line nut before the next fuel line nut is loosened. Tighten the fuel line nuts to 40 7 N m (30 5 lb ft). Continue the procedure until all of the fuel lines have been cleared of air. Make sure the fuel line nuts are tightened and the priming pump is locked before starting the engine.Air Cleaner
Clean/Replace Elements
Never run the engine without an air cleaner installed. Never run the engine with a damaged air cleaner. Do not use filter elements with damaged pleats, gaskets or seals. Dirt entering the engine causes premature wear and damage to engine components. Air cleaners prevent airborne debris from entering the engine through the air inlet.
Never service the air cleaner with the engine running since this will allow dirt to enter the engine.
If your air cleaner element becomes plugged, the air can split the element filter material. Unfiltered air will drastically accelerate internal engine wear. Your Caterpillar dealer has air filter elements to service this unit. Contact your Caterpillar dealer for the correct filter element.If the air cleaner indicator shows red at any time, clean the filter element or install a new element. Clean or replace air cleaner filter elements at least Every 250 Hours. Severely dusty environments may require more frequent air cleaner service.Refer to the Air Cleaner topic in the Daily section of this manual.Batteries
Clean/Check Electrolyte Level
1. Remove the filler caps. Maintain electrolyte level to bottom on fill plug openings.If the addition of water is necessary, use distilled water. If distilled water is not available use clean water that is low in minerals. Do not use artificially softened water.At proper charging rate, batteries should not require more than 30 cc (1 oz) water per cell per week.2. Keep batteries clean.3. Loosen and remove cable clamps from all battery terminals.4. Clean all battery terminals.5. Clean all cable clamps.6. Install and tighten cable clamps to battery terminals.7. Coat cable clamps and terminals with 5N-5561 Silicone Lubricant, petroleum jelly or MPGM grease.Check Battery Charger (if equipped)
* Check the battery charger for proper operation. If batteries are properly charged, ammeter reading should be very near zero. All batteries should be kept charged to a corrected specific gravity of 1.250 or above.* The batteries should be kept warm, if possible. The battery temperature affects the cranking power. If the battery is too cold, it will not crank the engine, even if the engine is warm.* When the engine is not run for long periods of time or is run for short periods, the batteries may not fully recharge. Ensure a full charge to help prevent the battery from freezing.Battery or Battery Cable Replacement
When replacing batteries or battery cables, use the following procedure.1. Turn off the START switch. Turn off (open)
