🚜💥 Busy week in the workshop!
Both of these Case IH 9380 Quadtracs came in with front and rear differentials making metal. After full rebuilds, they’re back in top shape and ready to hit the paddock again.

Nothing more satisfying than seeing big gear back to work! 👊

V8 Land Cruiser Ute in the workshop after the owner reported a turbo noise. 🛠️
Inspection revealed a chipped exhaust fin inside the turbo — traced back to a faulty boost control solenoid causing the engine to overboost.

Our team attended a Steiger 600 west of Moree to diagnose a misfire.
The issue was resolved with the installation of a new injector. During inspection, we identified a leaking turbocharger, which was also replaced during the visit to ensure the machine was operating at full capacity.

Differentials and transmission rebuilds are a core part of our workshop operations — and this 9380 is no exception.

🛠️ The differential centre was stripped and rebuilt after bearing and thrust washer failure.
🛠️ Both hubs required complete disassembly due to multiple gear and tapered roller bearing failures.

All components were inspected, clearances checked, and rebuilt to spec — now ready for reliable service in the field.

We hit the road to the VIC border for this one 🚛🔧

No job too big, no paddock too far 👊

Preventative Maintenance – Case IH 340 Magnum
Out at Myall Creek this week giving this 340 Magnum some much-needed attention to keep it running at its best.

✔️ Engine valve set
✔️ Accumulator pressure checks
✔️ Track alignment

Routine maintenance = less downtime and better performance.

Our team attended to a Case 9380 in the Toobeah, QLD region. Upon inspection, a failed cam box was identified in the Cummins 855 engine.
The repair was completed on-site with a replacement camshaft and new cam box assemblies.
All components were replaced on-farm, minimising transport and downtime for the customer.
