The Muncie A20-A1010-HX3PBPW or A20A1010HX3PBPW is a medium-duty clutch shift power take-off from the Muncie A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting pattern pairs with a shift cover that rotates 360 degrees, giving installers flexibility in tight chassis environments. A rotatable pump flange and extended-length PTO mounting fasteners further ease installation. Tapered roller bearings extend service life, and an increased-diameter output shaft handles higher drive loads. The design uses a proven clutch pack, minimized leak paths, and optimized gear geometry for quieter operation. Three housing arrangements are available across the A20 Series, and the unit is compatible with the EX Drive shaft extension. Call us to confirm proper fit for your specific transmission and application.
