A truck doesn't care if it's after hours.

A breakdown doesn't care if you've got deadlines to hit.

When something goes wrong, you need someone who can show up, diagnose the problem and get you moving again.

That's exactly what we do.

From diagnostics and electrical faults through to hydraulics, welding and general diesel repairs, Mainstream Diesel brings the workshop to you.

Another repair completed by the team at Mainstream Diesel 🔧

This diesel air compressor came into the workshop with a damaged exhaust system causing excessive noise and reduced performance. After a thorough inspection, we carried out the necessary exhaust repairs, replacing the failed sections and restoring the system back to proper working order.

The compressor is now running quieter, safer, and ready to get back on site doing what it does best.

If your machinery, generators, compressors, trucks, or equipment need repairs or maintenance, get in touch with Mainstream Diesel. We’re here to keep your equipment running reliably and minimise downtime.

A good diagnostic challenge for the team this week on a 20kVA TechnoGen generator fitted with a DSE (Deep Sea Electronics) controller.

The generator came to us with a no-start fault. After carrying out a systematic diagnosis and testing procedure, we traced the issue back to a failed solder joint on the controller circuit board.

The faulty connection was repaired by re-soldering the joint, restoring communication and allowing the generator to start and run correctly once again.

This job is a great reminder that not every fault requires expensive parts replacement—accurate diagnosis can save customers significant time and money.

If you're having issues with generators, heavy vehicles, or diesel equipment, get in touch with Mainstream Diesel. We specialise in finding and fixing the faults others can't.
