The Muncie A20-A1005-JX3IIPX or A20A1005JX3IIPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 series transmissions. The A20 series uses a proven clutch pack design with tapered roller bearings to extend PTO service life, and an increased-diameter output shaft for added durability. The shift cover allows 360-degree rotation, giving installers flexibility when routing shift linkage or air lines. A rotatable pump flange and increased housing clearance simplify installation in tight engine bays. Three housing arrangements are available within the series, and the unit is compatible with the EX Drive shaft extension. Extended-length PTO mounting fasteners and reduced leak paths round out the design. Call us to confirm the correct housing arrangement and output configuration for your specific application.
