The Muncie A20-A1009-HR1BBPX or A20A1009HR1BBPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. Torque ratings span a wide range of speed ratios from 5 through 15, covering applications from 74% engine speed up to 201% on the 3000 Series and 105% through 287% on the 4000 Series. The A20 Series carries a single intermittent/continuous torque rating, simplifying application selection. Three housing arrangements accommodate varied installation positions, and the shift cover allows 360-degree rotation for flexible mounting. Tapered roller bearings extend service life, and the increased output shaft diameter adds durability at the wheel end. Compatible with the Muncie EX Drive shaft extension.
