- Bucket Pins & Bushings on Loaders — Excessive wear due to extreme shock, high levels of water and abrasive dirt
- King Pins on Trucks — Excessive wear due to extreme shock, high loads and abrasive dirt
- Bearings on Vibratory Shaker Screens — Excessive wear due to constant shock environment and abrasive contamination
- Gear Boxes on Conveyors, Crushers & Mills — Overheated gear boxes due to extreme loading
- Conveyor Bearings — Short relubrication interval; lots of maintenance labor
- Dredge & Transfer Pump Bearings — Excessive heat, water wash out and resulting bearing loss
