The Muncie A20-A1010-HX1BBPX or A20A1010HX1BBPX is a 10-bolt clutch shift power takeoff built for Allison 3000 and 4000 series automatic transmissions. The shift cover rotates 360 degrees for flexible installation, and the pump flange is also rotatable to suit different hydraulic pump orientations. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension for added versatility. Tapered roller bearings extend PTO service life, while the increased output shaft diameter adds durability under load. Extended-length mounting fasteners, reduced leak paths, and increased installation clearance simplify fitment. The clutch pack carries a single intermittent/continuous torque rating across the speed range. Call us to confirm the correct speed ratio and housing arrangement for your application.
