The Muncie A20-A1012-HX1CB or A20A1012HX1CB is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 series transmissions. It features a rotatable pump flange and a shift cover that allows 360-degree rotation, making installation more accessible in tight engine bays. Tapered roller bearings and an increased-diameter output shaft contribute to extended service life, while a proven clutch pack design carries a single intermittent/continuous torque rating across multiple speed ratios. Three housing arrangements accommodate different installation needs, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the right configuration for your application.
