The Muncie A20-A1009-HX1CB or A20A1009HX1CB is a medium-duty, clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover allows 360-degree rotation for flexible mounting, and the rotatable pump flange simplifies hydraulic plumbing. Tapered roller bearings extend service life, while an increased output shaft diameter adds durability at the drive end. Reduced leak paths and extended-length PTO mounting fasteners address common installation pain points. The unit carries a single intermittent/continuous torque rating, comes in three housing arrangements, and is compatible with the EX Drive shaft extension. Call us at Pro Gear and Transmission to confirm the correct housing arrangement for your specific Allison application.
