The Muncie A20-A1012-HH3PBPX or A20A1012HH3PBPX is a medium-duty, clutch shift power take-off from the Muncie A20 Series, designed for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting uses extended-length fasteners and a shift cover that rotates 360 degrees, giving the installer flexibility in tight cab-over and vocational chassis environments. A rotatable pump flange adds further placement options at the output. Tapered roller bearings extend service life, and the increased output shaft diameter handles higher-torque hydraulic demands. The gear geometry is optimized to reduce noise, leak paths are minimized, and the clutch pack design carries a single intermittent/continuous torque rating across three available housing arrangements. The unit is also compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your specific chassis and transmission configuration.
