The Muncie A20-A1012-HX1CBPW-M3 (also shown as A20A1012HX1CBPWM3) is a 10-bolt clutch shift power takeoff built for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees and the pump flange is fully rotatable, giving installers flexibility in tight engine compartments. Increased clearance around the unit simplifies installation, and extended-length PTO mounting fasteners are included. Tapered roller bearings support the output shaft, which carries an increased diameter for added durability. The proven clutch pack uses a single intermittent/continuous torque rating, and the gear set is optimized for noise reduction. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct housing arrangement and ratio for your application.
