The Muncie A20-A1005-HX3PBBX or A20A1005HX3PBBX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees, and the pump flange is fully rotatable, giving installers real flexibility in tight engine compartments. Tapered roller bearings extend service life, and the increased output shaft diameter handles higher drive loads without deflection. The clutch pack design carries a single intermittent/continuous torque rating, simplifying spec selection. Three housing arrangements cover a wide range of installation angles, and extended-length PTO mounting fasteners ease final assembly. Compatible with the Muncie EX Drive shaft extension.
