Contact Us for Heavy Vehicle Repairs & Maintenance

Heavy Vehicles

Heavy vehicles are a class of vehicle that’s generally used in commercial applications. Under Australian law, these are defined as vehicles with a gross mass or trailer mass of no more than 4.5 tonnes when fully loaded.


Practically, this refers to most large commercial vehicles in the country, including trucks, buses and tractors. Heavy vehicles most often run on diesel engines for the sake of fuel efficiency and power.


Our mechanics are qualified to work on all heavy vehicles with diesel engines. We’ve been maintaining and repairing diesel vehicles for more than a decade, fixing everything from semis to industrial plant equipment.


We work on heavy vehicles for road and off-road use. Mobile cranes, plant equipment, agricultural equipment and other unusual vehicles can all be serviced and repaired by BDM Heavy Vehicle Repairs.

Light Vehicles

Along with heavy vehicles, we also service and repair light vehicles. These include cars, 4x4s and light trucks among other vehicles. We commonly service and repair 4X4s and light trucks along with heavy vehicles.


Not all light vehicles are diesels, but we can still service them anyway. Our specialty is diesel mechanical work, but our trained mechanics are skilled in working with petroleum engines as well.

Plant Vehicles

We work on mobile plant machinery and equipment used in various industrial and commercial sectors. Everything from earthmoving vehicles to mobile cranes and tractors is included in this category.


These heavy vehicles are generally not road-safe, so we send a mobile team out to do the work where the vehicles are. Our teams are comprised of a qualified diesel mechanic and as many supporting staff as necessary to get the job done well.


We work on plant vehicles in WauchopeKempseyTaree, Port Macquarie and beyond. Our staff are trained diesel mechanics who understand the ins and outs of all types of diesel motors, including those used in plant machinery.


Part of our plant vehicle servicing includes mobile crane inspections. We are an authorised inspection centre for crane inspections and safety certificates.

Mack, Volvo & UD

Because of our diesel mechanic expertise and experience dealing with Mack, Volvo and UD trucks, we are an official service centre. We work on trucks and vehicles from these manufacturers, including warranty fixes, regular servicing and repairs with genuine parts.


Our service is available for all makes and models from these and other manufacturers. We’re able to work on a variety of diesel and petroleum engine vehicles.

Frequently Asked Questions

  • What does a diesel mechanic do?

    A diesel mechanic is a trained professional who specialises in the repair, maintenance and servicing of diesel-powered vehicles and machinery. This includes trucks, buses, trailers, 4x4s, tractors and heavy equipment. Their job involves diagnosing mechanical and electrical issues, performing routine servicing, carrying out repairs, and ensuring vehicles meet safety and compliance standards. Diesel mechanics work on various systems including engines, brakes, suspension, steering and electrical components. Many also offer mobile services for roadside repairs and fleet maintenance.

  • How often should a diesel truck be serviced?

    The recommended service interval for a diesel truck depends on its make, model and how it’s used. Generally, heavy vehicles should be serviced every 10,000 to 20,000 kilometres, or every six months—whichever comes first. However, trucks used in harsh conditions, long-distance hauling or heavy towing may require more frequent servicing. Regular servicing includes oil and filter changes, brake checks, tyre inspections and general mechanical checks to ensure the vehicle remains safe, efficient and compliant.

  • What are common problems with diesel engines?

    Diesel engines are known for their durability, but they can still experience issues. Common diesel engine problems include fuel contamination, injector failure, turbocharger faults, clogged filters, overheating, and starting difficulties. Poor maintenance, contaminated fuel or excessive wear and tear can contribute to these issues. Early signs of diesel engine trouble include unusual noises, loss of power, excessive smoke, difficulty starting, and increased fuel consumption. Regular servicing by a qualified diesel mechanic can help prevent these problems.
