The Muncie A20-A1009-HX3II or A20A1009HX3II is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 series transmissions. The A20 Series features a shift cover with 360-degree rotation and a rotatable pump flange, giving installers flexibility in mounting orientation. Increased clearance around the unit simplifies installation in tight chassis configurations. The proven clutch pack design carries a single intermittent/continuous torque rating, which eliminates the guesswork of matching duty cycles to separate ratings. Tapered roller bearings extend service life, and the increased-diameter output shaft adds durability under sustained hydraulic drive loads. The unit is compatible with the EX Drive shaft extension and comes in three housing arrangements. Call us to confirm the correct configuration for your application.
