The AllDiesels difference

At AllDiesels we are first and foremost mechanics - this sets us apart especially when buying a second hand engine and for after-sales expertise.

Many used engine dealers are wreckers or dismantlers reselling engines without properly testing them or new engine dealers are sales agent selling new equipment without ever getting their hands dirty to understand their product.  

All of our engines are covered by warranty and all used engines are thoroughly inspected by our team of qualified diesel mechanics and load tested on our purpose built dyno.
