Wowing a Coal Mining Customer

Recently an Excel customer in New Mexico had a dragline breakdown and they contacted Dave Eagan, Director of Technical Support, for help with the replacement of the Center Pin (Journal) Bushing for a Marion® 8750M™ Dragline. Our standard lead-time was 4-5 weeks, but Dave checked with the Q-ROC team and was able to offer a 2-week turnaround. Then Dave received another call. The customer had measured the ID (inside diameter) of the housing that the bushing fits in and discovered that they had an “out of round” condition. The customer wanted our recommendation for a proper finished size of both the OD (outside diameter) and the ID. The Excel engineering team made a recommendation and the customer conferred with the OEM and the rebuilder. They decided to modify the OD of the bushing to fit the out-of-round bore.

As the final size was being determined, the casting had been poured and engineering created a drawing that was ready for production. The bushing went through the machining process, passed inspection, and was packed and shipped on its way to the anxious customer in less than one week after confirming sizes and less than two weeks from the initial communication. They were very pleased to receive the finished bushing, ready to install, and in a short time frame. The Excel team worked together once again to WOW the customer and get them back up and running with a customized solution.
