CAT AD63 Mid-Life Rebuild: Built Strong in the Goldfields
At Worthy Engineering, we take immense pride in every rebuild that rolls out of our Kalgoorlie workshop—and our recent mid-life rebuild of a CAT AD63 underground truck is no exception. This project was more than just a mechanical transformation. It was a testament to what can be achieved when a client backs a locally based, highly capable team. From initial inspection and teardown through to reassembly, rigorous testing, and final delivery, our tradespeople brought precision, experience, and pride to every stage. The result? A reliable, field-ready AD63 that’s now back underground and earning its keep. We sincerely thank our client for entrusting us with this important rebuild.
