The Muncie A20-A1012-HX1BS or A20A1012HX1BS is a medium-duty, 10-bolt clutch shift power take-off from the A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees for flexible installation positioning, and the rotatable pump flange simplifies hydraulic plumbing. Tapered roller bearings extend PTO service life, while an increased output shaft diameter adds durability at the drive end. The clutch pack carries a single intermittent/continuous torque rating, and three housing arrangements give installers options to suit the chassis. Extended-length PTO mounting fasteners and increased installation clearance reduce bay time. Compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
