The Muncie A20-A1005-HX11X or A20A1005HX11X is a medium-duty, clutch shift power take-off from Muncie's A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting pattern secures to the transmission, while a shift cover with 360-degree rotation and a rotatable pump flange simplify installation and plumbing orientation. Tapered roller bearings extend service life, and the increased output shaft diameter handles higher drive loads. A proven clutch pack delivers a single intermittent/continuous torque rating across the speed range, and maximized gear geometry keeps operating noise down. Three housing arrangements and compatibility with the EX Drive shaft extension add flexibility for varied installations. Available from Pro Gear and Transmission.
