The Muncie A20-A1010-HX3PBBX or A20A1010HX3PBBX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 series transmissions. The A20 series uses a proven clutch pack design with tapered roller bearings to extend service life, and features an increased-diameter output shaft for added durability. The shift cover rotates 360 degrees for flexible installation positioning, and the rotatable pump flange simplifies hydraulic plumbing. Extended-length PTO mounting fasteners and increased clearance make installation straightforward. Reduced leak paths and a maximized gear design keep operation quiet. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the right configuration for your application.
