One of the largest mining companies in the world decided to get more aggressive in fluid filtration and oil analysis to reduce emissions, extend equipment life and reduce maintenance and fuel costs. In one instance the team noticed the particle counts of copper and iron were increasing. Though particle counts were below the alarm limits of the manufacturer, the team decided to investigate. They found a fracture of a main bolt was causing excessive wear on the main and rod bearings. The team was able to avoid a catastrophic failure and have repairs covered under the manufacturer’s warranty.
