The Muncie A20-A1007-HR11XPX or A20A1007HR11XPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings for extended service life, and an increased-diameter output shaft for added durability. A rotatable pump flange and a shift cover with 360-degree rotation simplify installation and layout flexibility, while three housing arrangements let you configure the unit to the application. Reduced leak paths and a maximized gear profile keep noise low. The unit carries a single intermittent/continuous torque rating and is compatible with the EX Drive shaft extension. Call us to confirm proper fit for your specific transmission and chassis.
