The Muncie A20-A1010-HX5BS or A20A1010HX5BS is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. Part of Muncie's A20 Series, it carries a single intermittent/continuous torque rating across three available housing arrangements. The shift cover rotates 360 degrees for flexible installation positioning, and the rotatable pump flange simplifies hydraulic plumbing. Tapered roller bearings extend service life, an increased-diameter output shaft adds durability under load, and reduced leak paths cut maintenance time. The unit accepts the EX Drive shaft extension and ships with extended-length PTO mounting fasteners for added installation clearance. Call us to confirm the correct housing arrangement and output configuration for your specific truck or body build.
