The Muncie A20-A1008-HX1PBPX or A20A1008HX1PBPX is a medium-duty, clutch shift power take-off 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 rotates 360 degrees, letting installers orient the control port to suit tight engine compartments. A rotatable pump flange and increased housing clearance further simplify installation. Tapered roller bearings and an enlarged output shaft diameter extend service life, while a proven clutch pack design carries a single intermittent/continuous torque rating across the full speed range. 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.
