REQUIRED For Replacement labeled Engines, Long Blocks, and short blocks sold within the U.S. and U.S. Territories the engine core (i.e. old engine) that is removed MUST be returned to your selling Caterpillar dealer, so that they can return to Caterpillar OR destroy, as required by law. Proof of return or destruction will then be provided to the EPA and or California ARB if required. See PELJ1301 for additional details. The Primary Engine Arrangement converts the chemical energy stored in fuel into mechanical energy, which is harnessed to perform work. It achieves this through a controlled combustion process within its cylinders, resulting in the generation of high-pressure gases that drive the engine's pistons. This mechanical motion is then transferred to a crankshaft, which ultimately powers the vehicle. Attributes:• Rated gross power 55.4 kilowatts at 2200 revolutions per minute.• Peak torque 265 newton meters at 1500 revolutions per minute.• High idle 2420 revolutions per minute.• Low idle 1100 revolutions per minute.Applications: The Primary Engine Arrangement is used to generate power and drive equipment by converting fuel into mechanical energy through controlled combustion processes.
