Sidewinder 1800 rpm Generator Pulleys:
These CNC-machined pulleys are cut from ductile iron cast and allow you the option to run either 1 or 2 separate - 8 rib micro V groove belts for added reliability, more driving power, multiple engine operating speed or off-driving (using the alternator as a jackshaft). Some of our pulleys feature a pre-machined shoulder as well as pre-drilled and tapped 5 bolt pattern for the option of adding more flywheel effect (similar to the very heavy pulley on the original lister start-o-matic generator). These pulleys accept the heavier Q1 browning bushing with double slit and non-cut outer collar which are available for virtualy any generator shaft size you may have.
