The Muncie A20-A1006-XX1PBPX or A20A1006XX1PBPX is a medium-duty, 10-bolt clutch shift power takeoff engineered for Allison 3000 and 4000 Series transmissions. The A20 Series design centers on a rotatable pump flange and a shift cover that allows 360-degree rotation, giving technicians significantly more flexibility during installation and pump plumbing. Tapered roller bearings extend service life, and the increased-diameter output shaft adds durability under sustained load. A proven clutch pack with a single intermittent/continuous torque rating simplifies spec selection. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension. Extended-length PTO mounting fasteners and reduced leak paths round out the design. Call us to confirm the correct configuration for your application.
