At Mad Dog Diesel, we pride ourselves on providing maintenance and repair services for heavy mining and earthmoving equipment in Mackay and surrounding regions. Our trade qualified fitters are experienced in full machine rebuilds, component overhauls, diagnostic testing and all aspects of preventative maintenance, helping ensure your equipment runs efficiently without interruption. While we work on all makes and models of diesel machinery, we specialise in servicing Catepillar machines.

Over the last three years, we have built a reputation for delivering solutions that mining, civil and earthmoving businesses can depend on. Not only do we offer 24/7 breakdown response, we also provide on and off-site labour hire, allowing you to maintain efficiency and meet your contractual deadlines.

With more than 60 years' combined experience, there's no job too big or small for the Mad Dog Diesel team. Our services are available throughout Mackay, Moranbah, Dysart, Middlemount, Nebo, Glenden and Collinsville.
