The Muncie A20-A1010-HX3BABX or A20A1010HX3BABX is a medium-duty, clutch shift power take-off designed to mount on Allison 3000 and 4000 Series transmissions via a 10-bolt interface. The A20 Series design includes a rotatable pump flange and a shift cover with 360-degree rotation, which simplifies installation and gives the installer flexibility in routing. Tapered roller bearings extend PTO service life, and an increased-diameter output shaft handles higher-torque demands. The clutch pack design carries a single intermittent and continuous torque rating, and three housing arrangements are available to suit different truck configurations. Extended-length mounting fasteners and compatibility with the Muncie EX Drive shaft extension round out the series design. Call us to confirm the correct housing arrangement for your application.
