The Muncie A20 Series Power Take-Off, part number A20-A1008-HX1X4PX or A20A1008HX1X4PX, is a medium-duty, clutch-shift PTO engineered specifically for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting pattern pairs with a shift cover that rotates 360 degrees, making installation and orientation straightforward in tight engine compartments. A rotatable pump flange adds further flexibility for hydraulic plumbing. Tapered roller bearings and an increased output shaft diameter extend service life, while a maximized gear profile keeps noise down under load. Three housing arrangements and compatibility with the EX Drive shaft extension give this unit broad configuration options. Call us to confirm the right fit for your application.
