REPAIRS
We specialise in heavy vehicle repairs that actually keep your fleet moving — not just ticking boxes. With real hands-on experience in Road Ranger gearbox repairs, differential rebuilds, full engine overhauls, overhead/valve sets, and all the big jobs the OEMs like to pretend only they can do, we bring proper transport-industry knowledge to every repair.
Whether you’re dealing with a lazy gearbox, a diff that sounds like it’s blending gravel, or an engine that’s lost the will to live, we diagnose the actual cause — not just throw parts at it — and get it fixed right the first time. Downtime costs money, so we focus on quality workmanship, clear communication, and efficient turnaround.
Every job is done with precision, care, and a genuine passion for getting trucks back on the road in top shape. We make sure you understand the fault, the fix, and how to prevent it happening again. Fully equipped for major mechanical work and proud to offer honest, reliable service you can trust.
When your gear needs attention, we’re the ones who actually know what we’re doing — and we’re ready to prove it.
servicing
Regular servicing is the foundation of safe, reliable, and compliant fleet operation — but at Greater Western Mechanical, we don’t just tick boxes. We inspect everything. Every clamp, every hose, every bolt, bracket, and connection. If it can leak, loosen, wear out, squeal, or fall off — we find it before it fails.
Our servicing is designed for real-world transport conditions. We handle all makes and models of heavy vehicles, offering tailored servicing to suit your workload, operational needs, and maintenance schedule. Whether it’s a quick inspection, a full logbook service, or a custom preventative maintenance plan, we focus on stopping issues before they become breakdowns.
Because let’s be honest —
You don’t want to be stranded on the side of the road. And we’d rather not be called out to rescue something that could’ve been picked up in a proper service.

AIR CONDITIONING
A reliable air con system isn’t a luxury in WA — it’s survival. Whether you’re hauling in 45° heat or just trying to stop the cab from turning into a sauna, we keep your A/C blowing ice cold. From re-gassing and leak detection to compressor swaps and full-system diagnostics, we sort the problem properly the first time.
We don’t just give it a squirt and send you on your way. We track down the real cause — leaks, blockages, dodgy compressors, sticky TX valves, fried clutches, you name it — and fix it so it stays fixed. Quality parts, proper tooling, and no corner-cutting.
Stay cool, stay comfortable, and stay on the road with air conditioning repairs you can trust… and ones we won’t have to come rescue you from later.
COMPONENT
REBUILDS
When major components start getting tired, a proper rebuild can bring them back to life without the price tag of a full replacement. We offer professional rebuilds for gearboxes, diffs, engines, and other critical driveline components — done properly, with no shortcuts and no dodgy sealant fixes.
Every rebuild gets the full treatment: stripped down, inspected, cleaned, measured, machined where needed, and reassembled with quality parts and care. Because when you’re hauling big loads across WA, a sloppy rebuild will always come back to bite you. And honestly, we’d rather keep you moving than come rescue you on the side of the highway.
Whether you’re trying to squeeze more life out of a tired transmission or giving an old engine a second wind, you can count on us to rebuild it right — strong, reliable, and ready to work.
