The Muncie A20-A1007-HX3BBPX-XX or A20A1007HX3BBPXXX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series design centers on a proven clutch pack with a single intermittent/continuous torque rating, tapered roller bearings for extended service life, and an increased-diameter output shaft. The shift cover rotates 360 degrees and the pump flange is fully rotatable, giving technicians flexibility during installation. Reduced leak paths and a maximized gear design keep operation quiet. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension. Call us to confirm the right configuration for your application.
