The Muncie A20 Series power take-off, part number A20-A1007-HX1ZBPX or A20A1007HX1ZBPX, is a medium-duty clutch shift PTO engineered specifically for Allison 3000 and 4000 Series transmissions, mounting via a 10-bolt interface. Speed ratios available in this series range from 5 through 15, with single intermittent/continuous torque ratings published for each ratio. The shift cover rotates a full 360 degrees for flexible cab-to-transmission routing, and the rotatable pump flange simplifies hydraulic plumbing. Tapered roller bearings extend service life, and the increased-diameter output shaft handles higher load demands. Extended-length PTO mounting fasteners and reduced leak paths address common installation and maintenance concerns. Compatible with the EX Drive shaft extension. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
