The Muncie A20-A1008-HX1PB or A20A1008HX1PB is a medium-duty, clutch shift power takeoff from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting pattern pairs with a shift cover that allows 360-degree rotation, making installation positioning flexible. A rotatable pump flange and increased installation clearance reduce fitment headaches in tight engine compartments. Tapered roller bearings extend service life, and the increased output shaft diameter handles higher drive loads. The gear set is optimized to minimize operating noise. Three housing arrangements and compatibility with the EX Drive shaft extension give this unit broad configuration flexibility. Call us to confirm the right ratio and housing arrangement for your application.
