The Muncie A20-A1010-HX3PB or A20A1010HX3PB is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The A20 Series mounts with extended-length fasteners and features a shift cover that rotates 360 degrees, so installation orientation is flexible. A rotatable pump flange and increased component clearances simplify the installation process. Tapered roller bearings support the output shaft, and the increased output shaft diameter adds durability in demanding duty cycles. Gear geometry is optimized to reduce noise, leak paths are minimized, and the proven clutch pack carries a single intermittent/continuous torque rating across three housing arrangements. The unit is also compatible with the Muncie EX Drive shaft extension. Call us to confirm the correct housing arrangement and speed ratio for your specific application.
