This amount of amperage provides a constant DC voltage of 14.25 from idle on up. • The precision balanced rotor is vented to create better oil flow to the stator that helps to reduce the temperature by 50˚. • The large flange of the seal spacer provides additional support to the rotor without the use of a separate washer. • The series type regulator/rectifier is designed to reduce unnecessary drag on the engine by unloading the stator whenever the battery reaches full charge. • Provides the off-idle power required for fuel injected models. Model & Year Part # Big Twin 1970/1999 (except Twin Cam) with closed primary (oil bath type). 17838* Twin Cam 5 Speed 2003/2006 with closed primary (oil bath type). 17837 * 1970/1975 models will require a 2 bolt type regulator/rectifier mount, and 1970/1981 models may require slight clearancing of the primary covers. 40 AMP CHARGING SYSTEM FOR BIG TWIN Removing or installing the high output alternator rotor on the Milwaukee-Eight® requires a unique tool, and trust us, those magnets don’t budge easily. JIMS® understood that using pry bars or striking with a hammer can not only damage the rotor housing, but the magnets as well. This tool easily removes the rotor, while protecting the rare earth magnets within it. Use On Milwaukee-Eight® Engines 2017/Later ALTERNATOR ROTOR REMOVER AND INSTALLER Part 60861
