The Muncie A20-A1006-SX31XPX or A20A1006SX31XPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack with tapered roller bearings for extended service life, and an increased-diameter output shaft for added durability. The shift cover rotates a full 360 degrees for flexible mounting, and the rotatable pump flange simplifies hydraulic plumbing. Three housing arrangements are available, and the unit is compatible with the Muncie EX Drive shaft extension. Extended-length PTO mounting fasteners and reduced leak paths round out a design built for demanding medium-duty applications. Call us to confirm proper fit for your specific transmission and chassis.
