About us

About us

Adam Motoren GmbH is a medium-sized family business based in Hünxe on the Lower Rhine. For more than 30 years now, we have been active in the repair business for combustion engines on the market. Our focus is clearly on diesel engines for commercial vehicles and stationary applications.

Our customers are mainly located on the European continent and come from the heavy lifting branche, local & long-distance public transport, local and long-distance freight transport and the construction sector.

We see ourselves as a flexible, responsive and high-quality alternative to the original replacement engine. Our team, which has grown together over many years, has the most modern machine tools and testing machines at their disposal so that we can repair or overhaul your engine according to the state of the art.

Almost all value-adding processes are carried out in-house, whereby we achieve flexibility, speed and a high level of quality assurance.

Seamless documentation, continuously updated installation data and uncompromising testing at the end of installation are a matter of course for us and give you and last but not least us a clear conscience.
