The Muncie A20 Series power take-off A20-A1005-HX5PBPX-F3 or A20A1005HX5PBPXF3 is a medium-duty, clutch shift PTO engineered for Allison 3000 and 4000 Series transmissions. It mounts on a 10-bolt pad and features a shift cover that rotates 360 degrees, giving installers flexibility on tight firewall clearances. A rotatable pump flange, extended-length mounting fasteners, and increased clearance around the housing simplify installation. Tapered roller bearings protect the output shaft for extended service life, and the enlarged output shaft diameter handles higher drive loads. The unit is compatible with the EX Drive shaft extension and is available in three housing arrangements. Call us to confirm the right configuration for your application.
