Our dealer trained technicians carry decades of experience and expertise in diesel engine remanufacture and rebuild, with a special emphasis on off highway Caterpillar diesel engines. Our technicians operate a complete diesel engine component machine shop with the same equipment as the dealers where they generate a faster turnaround and build every engine according to customer order and factory specifications. All of our engines, whether new or OEM remanufactured, come complete, dyno tested with all new OEM parts. Our remanufactured CAT engines are COMPLETE builds from the block up. The block is flushed, cleaned, resurfaced and restored to 'like new' condition. We then replace ALL components with brand new CAT parts, needed or not. Our remanufactured engines meet the same specifications as new engines from the dealership. We also include thousands of dollars in additional new genuine CAT engine components that most dealers and other outfits don't, such as :  New Starter, New Alternator, New Belts, New Heat Shields, New Fan Groups, New Wiring Harness, New Sensors, New ECM and Much More.
