The Muncie A20-A1006-HX1IIPX or A20A1006HX1IIPX is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation, and the rotatable pump flange further simplifies fitment in tight spaces. Tapered roller bearings extend PTO service life, while an increased output shaft diameter handles higher torque demands. Muncie engineered the gear set specifically to reduce operating noise, and reduced leak paths mean fewer maintenance headaches in the field. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
