Thomas Classic

Thomas Classic have expertise gained over 40 plus years. With diesel engines and diesel fuel injection having been around a long time, our experience, knowledge, workshop and warehouse can help you with all of your classic engine needs.

Many names from the past no longer exist as trading companies and their parts and complete units become harder and harder to find. A lot of these engines are still running in agricultural machinery, buses, lorries and stationary applications like gen sets. Some examples from history are Gardner, Simms, Roosa Master, Sigma, Friedmann and Maier, Lucas CAV, AMBAC, Diesel Kiki etc.

We have stocks of parts and pumps that may be just what you need and we have good contacts around the world to helps us find what we don’t have. Also, we have a lot of technical information, parts manuals and test data that is now invaluable.

We have a very modern fuel injection workshop with some experienced technicians that can often put together what you need from core pumps and injectors, or service your old unit.

Everything we send out is fully tested and warranted.
