ALL CATERPILLAR DIESEL ENGINESThe Engine Horsepower Meter is an accurate fuel system diagnostic tool designed to help evaluate engine performance without costly disassembly or testing methods. A special fuel flowmeter measures the flow of fuel through the engine. After the BSFC (an expression of the engine's efficiency) and the fuel density (in pounds per gallon) are "dialed into" the Horsepower Meter, the Meter combines this information with the fuel flow rate and computes the horsepower that the engine's fuel system is capable of developing.It is not necessary to understand the theory or the electronics of the Meter in order to use it. However, it is preferable to have a serviceman with experience in engines and engine troubleshooting analyze the data and make other observations about engine condition.For information on determining corrected brake horsepower using correction factors and other reference material, see Special Instruction Form SEHS6947. For information on the troubleshooting and repair of the 5P2160 Engine Horsepower Meter Arrangement, see Special Instruction Form SEHS6948. 5P2160 Engine Horsepower Meter Arrangement

All hoses are a special rubber that is resistant to oil and diesel fuel. Do not substitute another type of hose; damage to the fuel flowmeter and engine fuel system may result. The minimum inside diameter of all fittings and hoses must be 3/8" (9.5).
