The Challenge
A Tier-1 mining company faced a significant operational setback when a WA1200 Komatsu loader began experiencing low power issues. The unexpected downtime disrupted production, leading to financial implications. Initial assessments pointed to a fuel pump failure, but the symptoms observed did not fully align with a typical pump malfunction, prompting further investigation.
Our Solution
Our team conducted a live diagnostic assessment, identifying a sudden drop in fuel pressure to 0 psi without stalling the machine. A closer inspection revealed three loose wires on the plug, which had caused intermittent power loss. After re-securing the wiring and conducting thorough system tests, we restarted the loader, ensuring stable fuel pressure and optimal machine performance.
The Result
The machine was fully operational within hours, avoiding an unnecessary $100,000 fuel pump replacement and minimising downtime. Our expertise delivered measurable savings and operational continuity. By addressing the root cause promptly, we prevented further operational disruptions, improved equipment reliability and restored full production capacity. This efficient resolution reinforced trust in our ability to provide effective, cost-saving solutions for complex mechanical challenges.
