The Muncie A20-A1005-HX3PBPW or A20A1005HX3PBPW is a medium-duty, clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and features a shift cover with 360-degree rotation, letting you orient the control to your cab layout without modifying the housing. A rotatable pump flange and increased clearance around the unit simplify installation in tight bays. Tapered roller bearings extend service life, while an enlarged output shaft diameter handles higher torque loads. The gear set is designed to keep noise low under load. Three housing arrangements give spec flexibility, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the right configuration for your application.
