Rebuilding our first Cat R3000H Underground Loader

Back in 2020, WesTrac Bathurst rebuilt the dealership's first Cat R3000H Underground Loader. It was rebuilt at 30,000 hours and will now do another 30,000; all for 65% of the price of a new machine. We've done a lot since then, but's interesting to look back and see what was achieved.
