Be sure the engine cannot be started while this maintenance is being performed. To prevent possible injury, do not use the starting motor to turn the flywheel.Hot engine components can cause burns. Allow additional time for the engine to cool before measuring/adjusting valve lash.Operation of Caterpillar engines with improper valve adjustments will reduce engine efficiency. This reduced efficiency could result in excessive fuel usage and/or shortened engine component life.
Check/Adjust
The procedures for engine valve lash should be performed according to the information in the Service Manual.Measure the valve lash with the engine stopped. To obtain accurate measurement, allow at least 20 minutes for the valves to cool to engine cylinder head and block temperature.
Initial valve lash check and/or adjustment on new or rebuilt engines is recommended at the first scheduled oil change interval, or 250 hours, whichever comes first. This is due to initial wear and seating of valve train components. Subsequent checks and adjustments should be made at Every 2000 Service Hour interval thereafter. Adjust the valve lash to the setting given in the chart above. Refer to the Service Manual or your Caterpillar dealer for the complete valve adjustment procedure. This maintenance is recommended by Caterpillar as part of a recommended preventive maintenance schedule to provide maximum engine life.Refer to the Engine Service Manual or your Caterpillar dealer for the complete procedure to perform this maintenance.Cooling System
Do not perform this maintenance until you read and understand the material in the Safety and Cooling System Specifications sections of this publication.This procedure is to be used for normal maintenance of cooling system surfaces to return to "like new" condition. For heavy build-up of scale and deposits, a severe acid-type commercial cleaner or mechanical cleaning will be required.
Refer to Cooling System Specifications for additional information regarding appropriate Flush/Fill for your application.Clean/Flush Coolant
1. Stop the engine and allow to cool. Loosen the radiator filler cap slowly to relieve any pressure and remove the cap. 2. Remove the plate and open the valve on the bottom of the radiator. The drain hose can be run to an outside container.Dispose of used engine coolant according to local regulations or recycle. Various methods have been proposed to reclaim used coolant for reuse in engine cooling systems. The full distillation procedure is the only method acceptable by Caterpillar to reclaim used coolant. 3. Remove the drain plug from the side of the cylinder block.4. When the system is completely drained, replace the cylinder block drain plug and close the radiator drain valve.Refill the cooling system using the fill cap located on the radiator top tank. Refer to "Cooling System Specifications" for the correct coolant mixture for your engine. The refill capacity is approximately 29 liters (7.7 U.S. Gal.).
