The Muncie A20-A1007-HX1PBPX or A20A1007HX1PBPX is a medium-duty, 10-bolt clutch shift power take-off designed specifically for Allison 3000 and 4000 Series transmissions. The A20 Series carries a single intermittent/continuous torque rating across its speed range, and the ratings table covers output speeds from 5 through 15, spanning engine percentages from 74% up to 201% on the 3000 Series and 105% up to 287% on the 4000 Series. A rotatable pump flange and shift cover with 360-degree rotation simplify installation and plumbing layout. The increased-diameter output shaft and tapered roller bearings extend service life, while the maximized gear design reduces operating noise. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct arrangement and speed ratio for your application.
