The Muncie A20-A1008-SX1BBPX or A20A1008SX1BBPX is a medium-duty, clutch-shift power takeoff engineered for Allison 3000 and 4000 Series transmissions, mounting via a 10-bolt bolt pattern. The A20 Series features a proven clutch pack design and tapered roller bearings for extended service life, an increased-diameter output shaft for added durability, and a rotatable pump flange with a shift cover that allows 360-degree rotation -- both designed to simplify installation and plumbing. Extended-length PTO mounting fasteners and reduced leak paths address common installation pain points. The unit is also compatible with the EX Drive shaft extension and is offered in three housing arrangements. Call us to confirm the correct configuration for your application.
