The Muncie A20-A1010-SX3X4PX or A20A1010SX3X4PX 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, giving installers flexibility in tight engine compartments. A rotatable pump flange and extended-length PTO mounting fasteners simplify installation, while the increased-diameter output shaft and proven clutch pack design are built for long service life. Tapered roller bearings extend PTO service intervals, and the gear set is shaped to minimize operating noise. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct housing arrangement for your application.
