The Muncie A20-A1006-HX1BB or A20A1006HX1BB is a medium-duty, clutch-shift power takeoff engineered 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 match your installation. A rotatable pump flange and extended-length mounting fasteners add flexibility; increased clearance simplifies installation in tight bays. Internally, tapered roller bearings extend service life and an enlarged output shaft diameter improves durability. The gear profile is designed to keep noise down, and the single intermittent/continuous torque rating simplifies spec work. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension. Call us to confirm the right configuration for your application.
