The Muncie A20-A1005-HX5CBPX or A20A1005HX5CBPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series carries a single intermittent/continuous torque rating across its speed range, simplifying spec selection. A 360-degree rotatable shift cover and rotatable pump flange give installers flexibility when working in tight engine bays, while extended-length PTO mounting fasteners and increased clearance reduce installation time. Tapered roller bearings and an increased-diameter output shaft extend service life, and the maximized gear profile keeps noise low. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Available from Pro Gear and Transmission. Call us to confirm the right configuration for your application.
