The Muncie A20-A1006-HX5II or A20A1006HX5II is a medium-duty, clutch-shift power take-off designed for Allison 3000 and 4000 Series transmissions. Part of the A20 Series, it mounts via a 10-bolt interface and features a shift cover with 360-degree rotation, letting you orient the control without repositioning the housing. A rotatable pump flange and three available housing arrangements add installation flexibility, while increased clearance around the unit simplifies access during the install. Tapered roller bearings extend service life, and the enlarged output shaft diameter improves durability under load. Gear geometry is optimized for noise reduction. The unit accepts the EX Drive shaft extension and uses extended-length mounting fasteners. Call us to confirm proper fit for your application.
