Long, long ago in a time before electric cars were even conceived, heavy duty diesel engines were first made. These engines were not like mass-produced automotive vehicle engines. There was no standard Make-Model-Year formula that magically gave all engines with the same model name the exact same parts. No, they were special; each individual engine was different as it came down the conveyor belt. And apparently the manufacturers didn't think about what a pain it would be in the future when you need to order parts for repairs.

Because of the lack of foresight, finding parts that correctly fit an engine can be incredibly complicated. Engine serial numbers are important because they are the only guaranteed way to find the exact parts that an engine was built with. Usually, if you're buying a single part, providing the part number off the old part will also work.
