The Muncie A20-A1007-JR1BAPX or A20A1007JR1BAPX is a medium-duty, 10-bolt clutch shift power takeoff engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design paired with tapered roller bearings to extend service life, and features an increased-diameter output shaft for added durability. A rotatable pump flange and shift cover with 360-degree rotation simplify installation and plumbing. The housing design reduces leak paths and supports three housing arrangements. Gear geometry is optimized to minimize noise, and a single intermittent/continuous torque rating simplifies spec selection. Extended-length PTO mounting fasteners and compatibility with the EX Drive shaft extension round out the installation options. Call us to confirm proper fit for your application.
