The Muncie A20-A1015-HX3CB (also referenced as A20A1015HX3CB) is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series design centers on a proven clutch pack with a single intermittent/continuous torque rating, simplifying spec selection. A 360-degree rotating shift cover and rotatable pump flange give installers genuine flexibility in tight engine compartments. Tapered roller bearings extend service life, and the increased output shaft diameter adds durability under sustained load. Three housing arrangements and compatibility with the EX Drive shaft extension keep mounting options open. Call us to confirm the correct ratio and housing arrangement for your application.
