The Muncie A20-A1005-HX3CBPX or A20A1005HX3CBPX is a medium-duty, clutch shift power take-off from Muncie's A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions via a 10-bolt mount. The shift cover rotates 360 degrees, and the pump flange is also fully rotatable, giving installers genuine flexibility in tight engine compartments. Tapered roller bearings extend PTO service life, and the enlarged output shaft diameter adds durability under sustained loads. A proven clutch pack design carries a single intermittent/continuous torque rating, simplifying spec selection. Three housing arrangements are available within the series. The unit is also compatible with the EX Drive shaft extension. Call us to confirm the correct housing arrangement and gear ratio for your specific application.
