The Muncie A20-A1010-HX3II or A20A1010HX3II is a medium-duty, 10-bolt clutch shift power takeoff engineered for Allison 3000 and 4000 series transmissions. It belongs to Muncie's A20 Series, which carries a single intermittent/continuous torque rating across three available housing arrangements. The shift cover rotates 360 degrees for positioning flexibility, and the pump flange is fully rotatable to simplify plumbing. An increased output shaft diameter adds durability, tapered roller bearings extend service life, and extended-length PTO mounting fasteners ease installation. The unit is compatible with the EX Drive shaft extension for additional reach. Call us to confirm the correct housing arrangement and ratio for your application.
