The Muncie A20-A1005-HX5IIPW or A20A1005HX5IIPW is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The rotatable pump flange and shift cover with 360-degree rotation give installers real flexibility in tight engine compartments, while the increased clearance housing simplifies the mounting process. Tapered roller bearings and an enlarged output shaft diameter extend service life under continuous duty cycles. The proven clutch pack carries a single intermittent/continuous torque rating, and the maximized gear geometry keeps noise down in operation. Three housing arrangements and compatibility with the EX Drive shaft extension make this unit adaptable across a range of truck upfit configurations.
