The Muncie A20-A1006-HX3X2PX or A20A1006HX3X2PX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The shift cover allows full 360-degree rotation, and the rotatable pump flange simplifies installation in tight bays. Tapered roller bearings extend PTO service life, and an increased-diameter output shaft handles higher drivetrain loads. Gear geometry is optimized to reduce operating noise, and reduced leak paths keep the unit cleaner over time. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
