Company Info
Big Bear Engine Company was originally founded as a division of a larger diesel engine remanufacturing company called Capital Reman in Denver, Colorado. As the company grew the demand for smaller industrial Caterpillar and Cummins crate diesel engines became apparent and Big Bear Engine Company spun off on its own underneath Capital Reman. Today the two companies still work side by side and are located in the same engine manufacturing complex.

Today we specialize in engine 3 models: Cummins 4BT Engine, Cummins 6BT Engine and the Caterpillar 3306 Engines. Our talents lie within the finite science of engineering and manufacturing of diesel engines. Big or small we’ve done them all! All of our engines are produced using brand new parts and are assembled to exact OEM tolerances.
In addition to new complete and long-block engines we also have the capabilities to remanufacture diesel engines. We can reman cylinder heads, camshafts, crankshafts, blocks, rocker assemblies. Surfacing, grinding, line boring, welding and magnafluxing are in our blood!
