Exchange of Parts
The Remanufactured Engine is built to the engine arrangement given in the chart. No modification or parts exchange is necessary if the replacement Remanufactured Engine Arrangement part number is the same as the original engine arrangement part number. Some modification or parts exchange may be necessary when the Remanufactured Engine Arrangement part number is different than the original engine arrangement part number.Use the reference literature indicated when it is necessary to exchange parts between the original engine and the Remanufactured Engine. Although some parts on the Remanufactured Engine may be different from those on the original engine, an exchange may not be necessary, depending upon the specific application.In some instances, it may be more advantageous to make minor modifications to the truck frame or engine mounting rails, rather than exchanging components between the Remanufactured Engine and the original engine.Before installation of the Remanufactured Engine, make sure the transmission mounting group, flywheel housing, flywheel, and vibration damper/crankshaft pulley are compatible with your application.Each Remanufactured Engine is rated at a specific horsepower (kW) at a specific rpm. The recommended Remanufactured Engine that is to be installed will not necessarily have the same exact horsepower (kW)/rpm rating as the original engine that it is replacing.If necessary, the horsepower (kW) and rpm setting of the recommended Remanufactured Engine can be adjusted to the same horsepower (kW) and rpm as the original engine. Always refer to the FUEL SETTING INFORMATION LIBRARY and/or the FUEL SETTING AND RELATED INFORMATION microfiche, Form SBFY1113, before making any changes to the fuel setting.For maximum life of the Caterpillar Remanufactured Engine, during the installation procedure be sure to check/inspect the following components for their condition and/or adaptability in the specific application.Sound Suppression
If the original engine has sound suppression material on the valve covers, oil pan and/or cylinder block, it is sometimes necessary, by law, to install sound suppression material on a replacement engine. It may be necessary to clean the valve covers of the old engine and exchange them with the valve covers on the Remanufactured Engine. Sound suppression that is on the old cylinder block and the oil pan can possibly be removed and installed on the Remanufactured Engine.Air Compressor
Since the air compressor uses engine oil for lubrication, be sure it is clean inside. Foreign material from a failure of the former engine can decrease engine life. A worn air compressor can also be the source of "oil consumption", by pumping oil into the engine air intake, or the vehicle air tanks.Air Cleaner
Install a new filter element in the air cleaner. Install all hoses and clamps as necessary. Check all piping and connections for leaks and make corrections as necessary.Radiator
Make sure the radiator is clean inside and out. Install new hoses and clamps. Check for leaks. If the engine is equipped with a viscous fan clutch, check fan speed to be sure of correct operation.Exchange those connections, such as inlet and/or outlet elbows, shunt line, etc., that are needed to connect the new engine to the vehicle cooling system.Water Separator
Some Remanufactured Engines that come from the factory do not have a factory installed water separator, however, it is a Caterpillar recommendation that a water separator be installed. Either transfer the water separator from the original engine, or, install a new water separator group on
