What is a diesel fitter?

More commonly called a Mobile Plant Mechanic these days, a diesel fitter is a mechanic who specialises in the repair and maintenance of engines and equipment.

This usually includes heavy vehicles, mining equipment, industrial and agricultural machinery. Diesel fitters and mobile plant mechanics handle everything from routine maintenance to major repairs, engine and transmission rebuilds, fault finding and more.

Diesel fitters apprentices perform tasks like:

  • Diagnosing faults
  • Testing and repairing engines, fuel systems and cooling components
  • Servicing and repairing hydraulic systems
  • Servicing and repairing transmissions and gearboxes
  • Routine servicing of diesel equipment
  • Using hand and power tools to perform repairs
  • Using lathes, welders and specialised equipment to fabricate and repair parts

To become a diesel fitter/mobile plant mechanic you will need to complete a 4-year apprenticeship which includes paid hands-on training and the study of a nationally accredited qualification.

Once you have completed your apprenticeship, you can work as a diesel fitter or mobile plant mechanic anywhere in Australia.
