The Muncie A20-A1012-HX5BS or A20A1012HX5BS is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series mounts with extended-length fasteners and accepts three housing arrangements, giving installers flexibility in tight underbody layouts. A 360-degree rotating shift cover and rotatable pump flange simplify plumbing and air-line routing, while increased clearance around the unit makes installation straightforward. Tapered roller bearings support the output shaft for long service life, and an enlarged output shaft diameter adds durability under sustained load. Maximized gear geometry keeps operating noise down. The unit is also compatible with the EX Drive shaft extension for applications that need added reach. Call us to confirm proper fit for your application.
