The Muncie A20 Series 10-bolt clutch shift power take-off, part number A20-A1010-JX3BBPX or A20A1010JX3BBPX, is a medium-duty PTO designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation, and the rotatable pump flange adds further positioning options. Tapered roller bearings extend service life, while the increased-diameter output shaft handles higher torque loads. Gear geometry is optimized to reduce noise, and leak paths are minimized throughout. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Extended-length PTO mounting fasteners are included. Call us to confirm the right configuration for your application.
