The Muncie A20-A1010-JX31XPX or A20A1010JX31XPX is a medium-duty, 10-bolt clutch shift power take-off from Muncie's A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees for flexible installation, and the rotatable pump flange simplifies hydraulic plumbing. Tapered roller bearings extend PTO service life, and the increased output shaft diameter adds durability under load. Reduced leak paths and a maximized gear design keep operation quieter. Three housing arrangements and compatibility with the EX Drive shaft extension give installers broad configuration flexibility. Compatible with Allison 3000 and 4000 Series transmissions.
