The Muncie A20-A1010-SX1X4PX or A20A1010SX1X4PX is a medium-duty, clutch shift power take-off from Muncie's A20 Series, designed for use with Allison 3000 and 4000 Series transmissions. The 10-bolt mounting pattern keeps the unit securely seated, while the shift cover rotates a full 360 degrees for flexible installation positioning. A rotatable pump flange and increased housing clearance simplify mounting, and extended-length PTO mounting fasteners are included. Tapered roller bearings and an increased-diameter output shaft extend service life, while a maximized gear design keeps noise down. The unit carries a single intermittent and continuous torque rating, is available in three housing arrangements, and is compatible with the Muncie EX Drive shaft extension.
