The Muncie A20-A1009-HX1BBPX or A20A1009HX1BBPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series delivers a single intermittent/continuous torque rating across all speed ratios, simplifying spec selection. Speed ratios range from 5 through 15, with 3000 Series engine percentage outputs from 74% up to 201% and 4000 Series outputs from 105% up to 287% depending on ratio. The shift cover rotates 360 degrees for flexible installation positioning, and the pump flange is also rotatable. Tapered roller bearings extend service life, and the increased-diameter output shaft adds durability under sustained drive loads. This unit is compatible with the EX Drive shaft extension.
