Have your diesel engine installed with confidence at Hendrix Diesel. Every one of our Jasper engines is backed by a nationwide warranty of up to 2 years unlimited mileage. We give every diesel engine a complete disassembled cleaning. The crankshafts are precision machined to exact tolerance and polished to a micro finish, then inspected with a profilometer. Camshafts are inspected for magnetism, demagnetized and precisely machined to provide correct life. The heads are resurfaced to assure a proper sealing surface with the block and a finish compatible with today's new gasket material. Every Jasper complete diesel engine is tested. All running complete engines are live-run dynamometer tested under varying loads simulating in-the-vehicle operation.
