The Muncie A20-A1008-HX3PBXX or A20A1008HX3PBXX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 series transmissions. The shift cover rotates a full 360 degrees for flexible mounting, and the rotatable pump flange simplifies hydraulic plumbing in tight installations. Tapered roller bearings extend service life, while the increased-diameter output shaft handles higher drivetrain loads. Extended-length PTO mounting fasteners and increased installation clearance cut bench time. The unit carries a single intermittent/continuous torque rating and comes in three housing arrangements, giving installers the layout that suits the chassis. Compatible with the Muncie EX Drive shaft extension. Call us to confirm the correct configuration for your transmission and application.
