The Muncie A20-A1015-SX31XPX or A20A1015SX31XPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series carries a single intermittent/continuous torque rating, simplifying spec selection. Three housing arrangements and a shift cover with 360-degree rotation give installers flexibility in tight engine compartments, while the rotatable pump flange and extended-length PTO mounting fasteners reduce installation headaches. Tapered roller bearings extend service life, and a maximized gear profile keeps operating noise down. The unit is also compatible with the Muncie EX Drive shaft extension for applications requiring added reach. Call us to confirm proper fit for your application.
