35 AGGREGATES MANAGER November 2015 EQUIPMENT MANAGEMENT tion. A tip that blunts is too big (has too much wear material), and the user should drop back to a sharper tip. It's important to discuss the particular application with the parts rep to get the best advice for tip matching. Remember, too, that wheel loaders are a different story because of their digging geometry. Inspections and corrections Edges and shells are places to watch in order to extend bucket life. Inevitably, there is a wear hot spot that devel- ops at the heel of the bucket and in the corners along that line. It's the result of scuffing during mostly the last part of the dig. Deeper buckets suffer heel wear faster. There is another wear hot spot at the front of the edge, in between each tooth adapter. Buckets with wider adapter spacing will experience faster and deeper wear than buckets with tighter tooth spacing. We call this type of edge wear "scalloping." My recommendation is to inspect the bucket regularly for heel wear and scalloping. At a point when the bucket wear bars become thin in the corners, they need to be completely replaced, or at least replace the outer portions of the wear bar on each side. In cases where the tip life is less than 200 hours, corner shrouds do a nice job of protecting the bucket corners. Regarding scalloping, in applications where tip life is less than about 400 hours, scalloping is a likely event, and in applications with a tip life of less than 200 hours, scalloping is inevitable. Cat buckets that are designed for high abra- sion applications come with segments between the teeth to control edge scalloping. If the excavator application presents scalloping risk, I recommend contacting the dealer parts rep for options. Wear material pieces, from chrome carbide pieces to hard strip stock, can be added between the bucket teeth to control edge scalloping. Work with your dealer to get full information about what to look for and how to repair or rebuild buckets. AM Doug Bye is the senior market professional with Cat Excavation Work Tools.
