Who we are

Big Bear Engine Company was originally founded as a division of a larger diesel engine remanufacturing company in Denver, Colorado. As the company grew the demand for smaller industrial Caterpillar and Cummins diesel engines became apparent and Big Bear Engine Company spun off on its own.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.

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!

We believe in putting our customers first and want everyone to have a pleasant buying experience. That means if there is any problem we aim to “make things right” at the end of the day. Whether you are installing at 4BT in a Jeep or a Skid Steer we are here to make sure you get the most of your engine.
