National Railway Equipment Co. provides both new and remanufactured diesel engines.
Prime Movers are remanufactured to the customer's specifications using OEM guidelines. Both AAR certified and ISO 9001:2000 registered, our granite table is utilized for dimensional checks to ensure all tolerances of the 'A' frame are repaired to OEM specifications. The main line bore is checked, welded and machined giving you a fresh line bore. The 'A' frame is then sent to one of our CNC milling machines for machining of all repaired surfaces including head surfaces, lower liner area and exhaust surfaces. Final checks are made on the 'A' frame. The 'A' frame is then matched to the oil pan and sent to the assembly line. All components and accessories are rebuilt by skilled craftsmen and supplied to the assembly line.
Upon completion of the assembly, prime movers are fully load tested in one of our test cell facilities. During the load test, bearing temperatures along with water, fuel and oil flows are monitored. Lube oil samples are lab analyzed and recorded as part of the engine build manual. The completed prime mover is then painted and prepared for shipment or installation into locomotives. All build documents are available to the customer upon request. By signing up for our innovative PRIME MOVER EXCHANGE PROGRAM, NREC will supply you a remanufactured prime mover in only two weeks.
