The Muncie A20-A1015-HX31X or A20A1015HX31X is a medium-duty, clutch-shift power take-off from Muncie's A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions using a 10-bolt mounting face. The shift cover rotates a full 360 degrees for flexible installation, and the rotatable pump flange simplifies hydraulic plumbing in tight chassis configurations. Increased clearance around the housing eases installation, while extended-length PTO mounting fasteners and a larger-diameter output shaft add long-term durability. Tapered roller bearings and a maximized gear profile reduce noise and extend service life. The unit is compatible with the EX Drive shaft extension and available in three housing arrangements. Call us to confirm the right configuration for your application.
