The Muncie A20-A1007-HX5BSBX or A20A1007HX5BSBX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. Part of Muncie's A20 Series, it features a rotatable pump flange and a shift cover with 360-degree rotation for flexible installation in tight engine compartments. Tapered roller bearings extend service life, and an increased-diameter output shaft adds durability under sustained hydraulic demand. The proven clutch pack design carries a single intermittent/continuous torque rating, simplifying application selection. Three housing arrangements and compatibility with Muncie's EX Drive shaft extension give installers mounting flexibility. Extended-length PTO mounting fasteners and reduced leak paths round out the design. Call us to confirm proper fit for your chassis and transmission build.
