The Muncie A20-A1007-HX1CB or A20A1007HX1CB is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series mounts via a 10-bolt pattern and uses a proven clutch pack design with tapered roller bearings to extend service life. The shift cover rotates 360 degrees for flexible installation routing, and the rotatable pump flange accommodates varied hydraulic plumbing layouts. An increased output shaft diameter adds durability under load, while extended-length PTO mounting fasteners and reduced leak paths simplify installation and maintenance. The unit is compatible with the EX Drive shaft extension and is available in three housing arrangements. Call us to confirm the correct configuration for your application.
