You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures. Alternator, Starting MotorInspect for Proper Operation
Caterpillar recommends a scheduled inspection of the alternator. Inspect for loose connections and proper battery charging. Inspect the ammeter gauge during engine operation to ensure the batteries and/or electrical system is performing correctly. Make repairs as necessary. Refer to the Service Manual for information.Check the alternator and battery charger for proper operation. If the batteries are properly charged, ammeter reading should be very near zero. All batteries should be kept charged. The batteries should be kept warm because 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 run for short periods, the batteries may not fully recharge. Ensure the alternator performs properly to charge the battery and to help prevent the battery from freezing.If the starting motor fails, the engine may not start in an emergency situation. Caterpillar recommends a scheduled inspection/check of your starting motor. The starting motor should be checked for correct operation. All electrical connections should be cleaned and checked. Refer to the established procedure for inspection and specifications in the Service Manual, or contact your Caterpillar dealer for assistance. Engine Water PumpInspect/Rebuild or Exchange
A failed water pump might cause severe engine overheating problems that could result in cracks in the cylinder head, a piston seizure or other potential damage to the engine.Visually inspect the water pump for leaks. If leaking is observed, replace all seals. Refer to the Service Manual for the procedure to replace the seals. TurbochargerInspect for Proper Operation
Turbocharger bearing failures can cause large quantities of oil to enter the sir intake and exhaust systems. Loss of engine lubricant can result in serious engine damage.Minor leakage of a turbocharger housing under extended low idle operation will not cause problems as long as no turbo bearing failure occurred.When a turbo bearing failure is accompanied by a significant engine performance loss (exhaust smoke or engine speed up at no load), DO NOT continue engine operation until the turbocharger is repaired or replaced.
An inspection/check of your turbocharger will minimize unscheduled downtime and reduce the chance for potential damage to other parts.Inspect/Check
1. Remove the exhaust outlet piping from the turbocharger. Visually check for leaks.2. Turn the turbine and compressor wheel by hand. The assembly should turn freely.3. Inspect the turbine wheel and compressor wheel for contact with with the turbocharger housing. There should NOT be any visible signs of contact between the turbine or compressor wheel and the turbocharger housing.4. Check the compressor wheel for cleanliness. If only the blade side of the wheel is dirty, dirt and/or moisture is passing through the air filtering system.If oil is found only on the back side of the wheel, it indicates a turbo oil seal leak. The leak may be the result of
