The Muncie A20-A1009-HX3CBPW-M3 or A20A1009HX3CBPWM3 is a medium-duty, clutch shift power take-off from Muncie's A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and features a shift cover with 360-degree rotation, allowing flexible installation orientation. The rotatable pump flange and extended-length mounting fasteners make fitment easier in tight engine compartments. Tapered roller bearings extend PTO service life, and an increased-diameter output shaft adds durability under sustained loads. The gear design is optimized to reduce noise, and reduced leak paths keep the unit clean in service. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct configuration for your application.
