Equipment Management • Check top and bottom rollers, as well as idler and sprocket for damage and excessive wear. Rollers should move freely. 7.Pay close attention to the bucket. High-cycle usage in the pit subjects the bucket to considerable wear. In the aggregate environment, it's essential to inspect the bucket for correct size, design, and wear. Operators should not run the teeth past 50 percent of their profile, at which point piercing ability and overall performance drops off rapidly. A fresh set of teeth and keepers should be readily available to prevent production interruptions. Buckets often have cutting edges, side cutters, and hard-faced surfaces that require inspection and upkeep. Inspect the bucket for developing cracks on a daily basis. Discovering these issues early will prevent expensive repairs and downtime. 8. Inspect the cooling system often. Keep the radiator, oil cooler, and other heat exchangers clean. Oil or coolant leaks can collect dust and debris, which slows air passage and act as an insulator to lessen the heat exchange. Be sure heat shields and insulation in the radiator and engine compartments are in place and in good condition. Missing components can affect the heat balance and lead to overheating. Replace coolant per the manufacturer's recommendation. Coolant additives (especially anti-corrosion additives) stop working over time. A calcium-like build-up can form in the radiator, engine block, and head; causing overheating and eventual engine failure. Tap into the experts With the remoteness of many operations, it's important for personnel to understand the ongoing health of the machines they operate. To acquire the knowledge and skills to carry out these maintenance functions, the manufacturer and the local dealer are always ready to assist in providing the necessary information and training so that when the day starts off, the excavator is ready to do its job.
