The Muncie A20-A1012-HX3BSPX or A20A1012HX3BSPX is a medium-duty, 10-bolt clutch shift power takeoff engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees, and the pump flange is fully rotatable, giving technicians flexibility when positioning the PTO during installation. Increased housing clearance simplifies fit-up. Tapered roller bearings extend service life, and the enlarged output shaft diameter adds durability at the drive end. Gear geometry is optimized for noise reduction, and reduced leak paths keep the unit cleaner in service. Three housing arrangements and compatibility with the EX Drive shaft extension give this unit broad installation flexibility. A genuine Muncie part, sold by Pro Gear and Transmission.
