The Muncie A20-A1007-H231XPX or A20A1007H231XPX is a medium-duty clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. Part of Muncie's A20 Series, it features a 10-bolt mounting pattern with three available housing arrangements and a shift cover that rotates 360 degrees for flexible installation. The rotatable pump flange and extended-length PTO mounting fasteners simplify fitment in tight engine compartments. Tapered roller bearings extend service life, and an increased-diameter output shaft handles higher torque demands. The maximized gear design reduces operating noise, and reduced leak paths cut maintenance intervals. This unit is also compatible with the EX Drive shaft extension. Call us to confirm the correct arrangement for your application.
