The Muncie A20-A1007-HX11X or A20A1007HX11X is a medium-duty, clutch-shift power take-off from the A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting uses extended-length PTO fasteners, and the shift cover rotates a full 360 degrees, giving installers flexibility to route shift linkage in tight cab configurations. A rotatable pump flange simplifies hydraulic plumbing, while increased housing clearance eases installation. Tapered roller bearings and an enlarged output shaft diameter address long-term durability under continuous hydraulic demand. The unit carries a single intermittent/continuous torque rating and is available in three housing arrangements. The design is also compatible with the EX Drive shaft extension for added reach. Call us to confirm the correct configuration for your transmission and application.
