The Muncie A20-A1010-SX1IIPX or A20A1010SX1IIPX is a medium-duty, clutch shift power take-off designed for Allison 3000 and 4000 series transmissions. It mounts via a 10-bolt pattern and features a shift cover that allows 360-degree rotation, giving installers flexibility in tight engine compartments. The rotatable pump flange, extended-length PTO mounting fasteners, and increased clearance simplify installation. Tapered roller bearings extend service life, and the enlarged output shaft diameter adds durability under load. The gear set is optimized to minimize operating noise, and reduced leak paths keep maintenance demands low. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct housing arrangement and ratio for your application.
