The Muncie A20 Series power take-off A20-A1005-HX3ZBPW or A20A1005HX3ZBPW is a medium-duty, 10-bolt clutch shift PTO designed for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation, and the rotatable pump flange gives you freedom in mounting orientation. Tapered roller bearings extend service life, and the increased-diameter output shaft handles demanding duty cycles. The clutch pack carries a single intermittent and continuous torque rating across three available housing arrangements. Gear geometry is optimized to minimize noise, leak paths are reduced by design, and extended-length mounting fasteners are included. This unit is also compatible with the EX Drive shaft extension.
