The Muncie A20-A1010-HX3BB or A20A1010HX3BB is a medium-duty, clutch shift power take-off from the Muncie A20 Series, designed for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting configuration pairs with a shift cover that rotates 360 degrees, giving installers flexible plumbing and wiring options. A rotatable pump flange and extended-length PTO mounting fasteners add further installation clearance. Tapered roller bearings and an enlarged output shaft diameter extend service life under continuous demand. The unit carries a single intermittent and continuous torque rating across three available housing arrangements, and accepts the Muncie EX Drive shaft extension for added reach.
