The Muncie A20-A1012-HX1IIPX or A20A1012HX1IIPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series carries a single intermittent/continuous torque rating across its speed range, simplifying application selection. A rotatable pump flange and a shift cover with 360-degree rotation give installers flexibility in tight engine bays, while extended-length PTO mounting fasteners and increased housing clearance ease the install. Tapered roller bearings extend service life, and an increased-diameter output shaft adds durability under sustained load. The unit is also compatible with the EX Drive shaft extension. Call us to confirm the correct speed and housing arrangement for your specific application.
