The Muncie A20-A1012-SX3CBPW or A20A1012SX3CBPW is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 series transmissions. The A20 series mounts with extended-length PTO fasteners and accepts three housing arrangements, giving installers flexibility for tight truck applications. A rotatable pump flange combined with a shift cover that allows 360-degree rotation simplifies both installation and plumbing layout. Tapered roller bearings and an increased-diameter output shaft extend service life, while a maximized gear design keeps noise low. The unit carries a single intermittent and continuous torque rating and is compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
