In many cases, Cat® and MaK™ parts are built to be rebuilt for multiple lives. This allows our customers to achieve like-new performance from parts at a fraction of the cost of buying new, reducing operating costs and increasing profitability.

The MaK Repair and Exchange Parts (REParts) program offers extensive repair and exchange options for MaK parts. Our customers get maximum engine productivity and lower life cycle costs while reducing their impact on the environment.


Our state-of-the-art salvage and cleaning techniques, quality control, and rigorous testing ensure that MaK REParts deliver the same quality and reliability as new parts. They’re easy to install and readily available, so you can minimize downtime and increase vessel availability.


We also accept returns on used parts, helping our customers further defray repair or replacement costs. When you use Mak REParts, you can rest assured that they deliver the quality you expect at a price that can significantly improve your profits.
