Luck Stone representatives highlight the features and benefits of a recent 777C Off Highway Truck repower that used a new Cat(R) C32 Tier 2 engine.



A Repower replaces an in-use engine system with a new or remanufactured engine system. Machines equipped with lesser-regulated engines, such as unregulated or U.S. EPA Tier 1 engines can be repowered to meet emission standards and some repowers may provide additional owning and operating savings such as improved fuel economy.
