Refer to the Service Manual or contact your Caterpillar dealer for assistance with removal and installation of engine components.Water Pumps
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.Alternator
Caterpillar recommends a scheduled inspection of the alternator. Inspect the alternator 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.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.Starting Motor
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.
