major mechanical repairs & rebuilds

overhauls & repowers

At times, Diesel Systems recommends engine overhauls rather than buying new.

In this case, we assess the cost verses benefits in rebuilding. We carefully determine what is in need of repair and what is not. This is where our expertise really counts; we provide cost-effective solutions when dealing with mechanical issues.

If our client chooses to rebuild the existing engine, we apply the latest technologies in restoring the original specifications and high performance it once had, complete with warranties and suggested preventive maintenance programs.

Diesel Systems is the best choice for all your engine overhaul needs.

We perform work on major marine brands such as: Detroit Diesel, Caterpillar, Cummins, MTU, Ford, Volvo, and Hino.

Our knowledgeable diesel mechanics are always here to help assist and give technical advice when you need it most.
