The Muncie A20-A1009-HX3X4PX or A20A1009HX3X4PX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series design centers on a proven clutch pack with a single intermittent/continuous torque rating, tapered roller bearings for extended service life, and an increased-diameter output shaft. The shift cover rotates 360 degrees, and the rotatable pump flange simplifies installation alongside the extended-length PTO mounting fasteners.
