The Muncie A20-A1006-JX3X4PX or A20A1006JX3X4PX is a medium-duty, clutch-shift power take-off designed for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and uses a proven clutch pack design with tapered roller bearings to extend service life. The shift cover rotates 360 degrees and the pump flange is fully rotatable, giving installers flexibility in tight mounting situations. An increased output shaft diameter adds durability under load, and the gear geometry is optimized to reduce operating noise. The unit carries a single intermittent/continuous torque rating, is available in three housing arrangements, and accepts the EX Drive shaft extension. Extended-length PTO mounting fasteners and a design with reduced leak paths round out the package. Call us to confirm proper fit for your application.
