Do you have an engine that needs rebuilding or reconditioning?

We are Australia's largest engine rebuilders and re-conditioners specialising in US & European heavy diesel engines. Our team of highly skilled in-house mechanics will have your engine running better than ever!


Brands we most regularly rebuild include Caterpillar, Cummins, DAF, Detroit, Iveco, MACK, MAN, Mercedes, Perkins, Scania, & Volvo. 

Our team of specialist diesel mechanics build in excess of 200 diesel engines each year for our own inventory and to customer specification. Our family has been serving the diesel engine industry for more than 50-years and across three generations. Over that time we have amassed a team of specialists, considerable experience, and expertise that gives our customers the confidence and peace-of-mind that they are dealing professionals who know what they are doing and will do the job the right way.

Too often do people learn the hard way, getting rebuilds done with a one-man band who may build a few engines a year at most, lacking both expertise and resources. Our rebuilding capabilities are unique and we have a proven track record that is second-to-none.

We have rebuilt literally thousands of engines for our customers, from small owner-operators to Australia's leading private operators, fleets and ASX-listed companies. 


We also deal in trade-ins, swaps and will consider part payment through trade of your current engine. 

Through our tailored service we will work with you to find a solution that is within your requirements and budget.

We can use a range of new and used, OEM and non-OEM quality parts to suit your comfort and situation.


Our team of experts can guide you through these decisions and provide you with the benefits and costs on a range of options.

At our purpose built facility, we can rebuild anything from smaller 4 and 6 cylinder diesel engines through to 100 litre+ powerhouses!
