Engine Rebuilds & Replacements
When an engine reaches the end of its life or suffers major damage, rebuilding or replacement is often the best solution. Engine rebuilds involve stripping, cleaning and replacing worn internal parts such as pistons, bearings and gaskets to restore performance and efficiency. Replacements are available for engines that can’t be repaired safely or economically. Both processes improve reliability and fuel economy while extending the lifespan of your vehicle. Professional engine work ensures proper calibration, emissions compliance and smooth power delivery. Regular servicing and oil changes can help prevent the need for major rebuilds in the future.
Diesel Diagnostics
Modern diesel engines rely on advanced electronic systems that control fuel injection, turbocharging and emissions. When something goes wrong, accurate diagnostics are key. Using specialist diagnostic tools, mechanics can identify issues like injector faults, sensor failures, turbo lag or poor fuel pressure. This data-driven approach allows for precise repairs without guesswork, saving time and reducing costs. Regular diagnostic checks also help maintain fuel efficiency and prevent breakdowns by catching problems early. Whether it’s a rough idle, smoke from the exhaust or poor acceleration, professional diesel diagnostics pinpoint the root cause quickly and accurately.
Light & Heavy Truck Servicing
Trucks and commercial vehicles require specialised servicing to stay compliant and dependable. Servicing includes oil and filter changes, brake inspections, driveline checks and comprehensive safety testing. Light truck services focus on maintaining performance for utes and delivery vehicles, while heavy truck services cover larger vehicles and long-haul operations. Proper maintenance reduces wear, improves reliability and helps prevent costly downtime. Mechanics also check tyres, suspension and electrical systems to ensure everything functions safely. Keeping up with scheduled truck servicing supports fuel economy, reduces breakdowns and keeps vehicles road-legal for business and trade use.
Fleet Maintenance (Iveco, Fuso)
Fleet maintenance keeps multiple vehicles performing at their best while minimising operational disruptions. Services are tailored to the unique needs of each fleet, from local delivery utes to heavy-duty Iveco and Fuso trucks. Mechanics perform regular inspections, logbook servicing and preventative maintenance to identify potential issues early. This proactive approach reduces unexpected breakdowns, keeps your vehicles compliant and extends lifespan. Fleet maintenance programs can be scheduled around your business operations, ensuring minimal downtime. Maintaining a consistent service history also supports warranty coverage and resale value, making it a smart investment for growing businesses.
Fleet Servicing
Fleet servicing provides ongoing care for multiple vehicles through structured maintenance plans. Regular servicing ensures consistent performance across all vehicles and simplifies recordkeeping for business owners. Mechanics track each vehicle’s mileage and servicing schedule to guarantee compliance and reliability. This helps reduce repair costs, fuel consumption and unexpected downtime. Fleet servicing covers everything from engine checks and brake inspections to oil changes and road safety tests. With professional fleet servicing, your business can operate smoothly knowing every vehicle is road-ready, compliant and efficient, keeping your team productive and customers satisfied.
FAQ
How often should a diesel truck be serviced?
Diesel trucks should be serviced every 10,000–15,000 km, depending on workload and manufacturer guidelines. Regular servicing includes oil and filter changes, fuel system inspections and diagnostics. Adhering to this schedule keeps engines efficient and prevents costly breakdowns.
Why does my diesel engine produce black smoke?
Black smoke typically indicates incomplete fuel combustion caused by issues like clogged injectors, dirty air filters or turbo problems. It’s important to have your vehicle diagnosed promptly to prevent damage to the engine or exhaust system.
What are common signs of a failing truck clutch?
Signs of clutch wear include slipping under load, difficulty shifting gears, and vibrations during engagement. If ignored, the clutch may fail entirely, leaving the vehicle undriveable. Regular servicing helps identify clutch wear before it becomes a major issue.
