A20-A1010-HX3TAPX Muncie 10-Bolt Clutch Shift PTO

The Muncie A20-A1010-HX3TAPX or A20A1010HX3TAPX is a medium-duty, 10-bolt clutch shift power takeoff designed for Allison 3000 and 4000 Series transmissions. The A20 Series carries a single intermittent/continuous torque rating, which simplifies application selection. Three housing arrangements are available, and the shift cover rotates a full 360 degrees for flexible mounting. A rotatable pump flange, extended-length PTO mounting fasteners, and increased clearance all reduce installation time. Tapered roller bearings extend service life, and the increased-diameter output shaft adds durability under sustained loads. The unit is also compatible with the Muncie EX Drive shaft extension.
