The Muncie A20-A1010-RS31XPX or A20A1010RS31XPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 series transmissions. The A20 series features a shift cover with 360-degree rotation, a rotatable pump flange, and extended-length PTO mounting fasteners that simplify installation in tight engine compartments. Tapered roller bearings extend service life, and the increased output shaft diameter adds durability under sustained load. Three housing arrangements give installers flexibility for different mounting configurations, and the unit is compatible with the EX Drive shaft extension. A proven clutch pack design and maximized gear geometry keep operating noise in check. Call us to confirm the right configuration for your application.
