New aluminum power pulley (5 3/4" diameter), cut for Wasserboxer engine seal. This is perfect for your high-performance wasserboxer or oxyboxer conversion. $50 shipped in the CONUS (please inquire for international shipping), or trade for a new 5" diameter dry sump pulley with Type 1 labyrinth seal (<---I need to start with this to turn the pulley down to the Wasserboxer seal diameter...a Type 1 sand-seal is too small).
