The Muncie A20 Series power take-off, part number A20-A1010-HX1ZBPX or A20A1010HX1ZBPX, is a medium-duty 10-bolt clutch shift PTO engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees, giving the installer flexibility in routing and plumbing. A rotatable pump flange and increased housing clearance further simplify installation in tight engine compartments. Tapered roller bearings extend service life, and an enlarged output shaft diameter adds durability under load. Gear geometry is optimized to reduce operating noise, and reduced leak paths cut the chance of fluid loss at the housing. The unit carries a single intermittent/continuous torque rating and is compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
