The Muncie A20-A1010-HX1PB or A20A1010HX1PB is a medium-duty, clutch-shift power take-off designed specifically for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and features a shift cover with 360-degree rotation, giving installers flexibility in tight cab or frame configurations. The rotatable pump flange and extended-length PTO mounting fasteners simplify installation, while increased clearance reduces fitment headaches. Tapered roller bearings extend service life, and the enlarged output shaft diameter adds durability under load. Gear geometry is optimized to reduce operating noise, and a single intermittent/continuous torque rating streamlines application selection. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Available from Pro Gear and Transmission - call us to confirm the right configuration for your application.
