The Muncie A20-A1011-HX1CBPW or A20A1011HX1CBPW 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 tapered roller bearings for extended service life, an increased output shaft diameter for added durability, and a rotatable pump flange for flexible plumbing. The shift cover rotates a full 360 degrees, and three housing arrangements let you match mounting to your chassis. Extended-length PTO mounting fasteners and increased installation clearance simplify the swap. The unit also supports the Muncie EX Drive shaft extension and features minimized leak paths plus gear geometry tuned to reduce operating noise. Call us to confirm proper fit for your application.
