The Muncie A20-A1007-SX1IIPX or A20A1007SX1IIPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series design centers on a rotatable pump flange and a shift cover with full 360-degree rotation, which together simplify pump mounting and installation clearance. Tapered roller bearings extend service life, and the increased output shaft diameter adds durability under load. A single intermittent/continuous torque rating simplifies spec selection, and the unit is compatible with the EX Drive shaft extension. Three housing arrangements let you match the PTO to your mounting requirements. Call us to confirm the correct configuration for your application.
