The Muncie A20-A1011-HX3CBPW or A20A1011HX3CBPW is a medium-duty, 10-bolt clutch shift power take-off from Muncie's A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the rotatable pump flange gives installers the flexibility needed on tight chassis applications. Tapered roller bearings extend PTO service life, while an increased-diameter output shaft handles higher driveline loads. The clutch pack design carries a single intermittent/continuous torque rating across the speed range, simplifying spec'ing. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
