* The power rating of the engine indicated in this document is the net power output tested on a production engine for the engine model and measured in accordance with SAE J1349 at 4,500, 4,000 or 3,600 rpm (Engine Net Power) and at 3,000 or 2,500 rpm (Engine Max. Net Torque).
Mass production engines may vary from this value . Actual power output for the engine to be mounted on the manufacture of the final machine will vary depending on many factors , including the operating speed of the engine in application , environmental conditions , maintenance and other variables .
