THE BLACK EDITION™ ENGINE OVERHAUL PROCESS: ELECTROSTATIC POWDERCOATED

Harley Davidson Uses Powdercoating

This unique FAA accepted dry coating process is proprietary to "Power By Victor"™ engines and has become a trademark of our lasting engine quality. Production built engines come with little or no corrosion protection and are subjected to oxide corrosion of the crankcase in a very short time. As a result, Victor has developed a unique process to protect your investment with the application of a special Black Edition II™ powdercoat.

This is a dry coating in which electrostatically charged particles of special resins and pigments are sprayed onto the crankcase and related components. The engine's power section is first assembled under torque and all machined surfaces are protected from powder application. Then the engine is pre-heated to relieve the aluminum parts from hydrogen gas pockets that collect within the case material. After degassing of the assembly, the engine goes to the powdercoat lab, the engine block is charged negatively and positively-charged powdercoat particles are applied. After powder application, the entire power section goes into a curing oven where the powder melts and saturates into the porous surface cavities of the crankcase, sealing off all air pockets. This fusion of powder application fills the rough, porous surface to prevent corrosion and reduces surface fatigue, one of the major contributors to crankcase cracking. The engine is then dissembled and prepared for final engine assembly.

Many other external parts of the engine are also hand prepared and treated with powder to provide for the finest finishing process available. Another distinct advantage of powdercoating is that the surface of the engine case becomes smooth instead of its rough original finish. This change in surface smoothness aids in a more equal dispersion of heat from the engine and further reduces the risk of crankcase cracking while improving the rate of heat dispersion. The black color pigment is significant because it aids in heat dispersion. Automobile manufacturers finish all engine radiators in black for this very reason. Powdercoat application is another demonstration of how far the "Power By Victor"™ commitment goes to insure lasting, superior quality in every Black Edition II™ Engine.
