Engines are the heart of every truck, and at Maude Diesel, they’re our specialty. Our mechanics are highly trained in fault diagnosis, rebuild procedures, and major component overhauls across a wide range of heavy-duty diesel engines. We take the time to properly inspect, strip, assess and rebuild engines with precision and care – whether it’s for a single truck or part of a larger fleet.
We work with all engines and specialise in the following:
-
Cummins engines – ISX, X15, Signature Series and more
-
CAT engines – C15, 3406E, ACERT range
-

We work on all the big names in the industry, including Cummins, CAT and Detroit – just to name a few. Whether you’re running a prime mover, tipper, farm truck or fleet vehicle, we have the tools and expertise to keep your engine performing at its best.
