The Muncie A20 Series 10-Bolt Clutch Shift Power Take-Off, part number A20-A1007-HH1BBPX or A20A1007HH1BBPX, is a medium-duty PTO designed for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is rotatable as well, giving installers flexible orientation options. Tapered roller bearings extend service life, and an increased-diameter output shaft adds durability under load. The unit carries a single intermittent/continuous torque rating across three available housing arrangements, and its gear geometry is optimized to minimize operating noise. It is also compatible with the EX Drive shaft extension. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
