The Muncie A20-A1011-HX1BBBX or A20A1011HX1BBBX is a 10-bolt clutch shift power takeoff built for Allison 3000 and 4000 series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is also rotatable, giving installers flexibility in tight chassis configurations. Increased clearance simplifies mounting, and extended-length fasteners accommodate various housing arrangements - three housing configurations are available. Tapered roller bearings extend service life, and the increased output shaft diameter adds durability at the driven end. The gear design is optimized to minimize operating noise, and reduced leak paths keep the unit cleaner in service. Compatible with the EX Drive shaft extension. Call us to confirm the right configuration for your application.
