Remanufacturing Evolutions By Harley-Davidson

We jumped at this opportunity to cover the Harley-Davidson factory Evolution remanufacturing process from start to finish. If you have an engine remanufactured by the factory, removed and replaced at a dealership, your warranty is restored. The factory is also capable of remanufacturing your original powerplant or replacing it with a new, very reasonably priced unit containing your original VIN. Options such as chrome or polished engines are also available.

It starts with your dealer removing your engine and shipping it to the Factory's Capitol Drive Facility in Milwaukee. When it reaches the factory, they will unpack and prep it for disassembly. The process from the factory costs $2,000 for an Evo engine and $2,200 for a black and chrome job. Your dealer will probably also charge you for R&R. Twin Cams are slightly higher, but there's more options. You can ship your Twin Cam engine and the factory will install a big bore kit and reman your engine at the same time.

The new engine and reman program started in 1999, and it takes only two weeks from the time your baby lands in Milwaukee before it's shipped back home. The factory runs through about 1,500 reman Evos a year and sells almost 2,500 new engines. Quality engine parts can be remanufactured to original specs and saved, while others are discarded. All reusable parts are cleaned and freshly powercoated. Reusable parts are machined, rehoned, and rebored to exact tolerances, and then passed through rigid specification checks.

Crankcases are set, bearings pressed, and parts reassembled. Chromed and polished parts are replaced. Each engine is upgraded to meet the latest specifications where possible. For compliance and warranty program acceptance, all engines will be built with stock camshafts. If you have installed performance cams, they will be discarded and replaced with the stock versions before your engine is returned. You might consider installing a stock cam before beginning this process.
