With advances in engine technology over the past 20-30 years, a series of engines differing in horsepower, maximum torque and torque curves can be produced from a single engine series by varying the combinations of parts used to build the engine.
For example, changing compression ratios with the use of different pistons, altering fuel delivery settings and timing using different pumps and injectors, as well as the use of different turbochargers and more.
Each combination has it’s own unique engine serial number, arrangement number or build number. Therefore the importance of correct engine identification is crucial when attempting to order construction equipment replacement parts to ensure the correct parts are obtained for your particular build of engine. This information is typically found on a tag, sticker or stamped into the engine block somewhere. The locations vary by manufacturer and model series. Future posts will discuss the specific locations for each individual manufacturer.
