The Muncie A20-A1006-SX3CBPW or A20A1006SX3CBPW 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 available speed ratios, with HP ratings ranging from 74% to 201% of engine speed and torque ratings from 400 lb-ft down to 205 lb-ft depending on the ratio selected. Three housing arrangements are available, and the shift cover allows 360-degree rotation for flexible installation. A rotatable pump flange, increased output shaft diameter, and extended-length PTO mounting fasteners reduce installation complications. The design is compatible with the EX Drive shaft extension. Call us to confirm the correct ratio and housing arrangement for your application.
