Rebuilding Little Things, Too

September 28, 2010

At Rinker Materials' quarry in Macon, Ga., Cat 980G loaders are brought in new, run three years, and with 15,000 hours on the hour meter they're rebuilt from the power train to the hydraulic hoses.

"When we do a power train, we pull and rebuild the engine, transmission, torque converter, differentials, final drives—everything," says Dave Venrick, mobile equipment manager. "After we get the major components out of the frame, we really get in there and work over the hoses, wiring harnesses, and all the other stuff you can't see when components are in there. The idea is to eliminate failures in those systems while we're doing the component rebuilds. A drive train doesn't give you a lot of problems when it's maintained properly. But every day you break hoses."
