JASPER remanufactured products meet, or exceed, original specifications and, where applicable, improve OEM design with updated parts and precise machining. JASPER takes a cellular approach to remanufacturing, with teams, known as PODs, that specialize in producing a specific product or product family. JASPER’s POD cross training provides the highest quality, the best efficiency, and ultimately brings you better value.
Each JASPER product is subjected to a specific set of tests and calibrations during the inspection and building processes. Gas engines are live-run tested to ensure proper compression, vacuum and oil pressure. Transmissions are dynamometer tested under load to ensure proper gear ratios, line pressure, cooler pressure and flow. Running Complete Diesel engines are dynamometer tested under varying loads to simulate in-the-vehicle operation, including a final engine run-in and inspection to ensure peak performance and operating efficiency.
