The Muncie A20-A1009-SX1CBPW or A20A1009SX1CBPW is a medium-duty, clutch shift power take-off designed specifically for Allison 3000 and 4000 Series transmissions. The A20 Series mounts on a 10-bolt pad and features a shift cover with full 360-degree rotation, giving installers flexibility when routing shift actuation hardware. A rotatable pump flange and increased housing clearances make installation more straightforward in tight engine compartments. Tapered roller bearings extend PTO service life, and the increased-diameter output shaft handles higher drive loads. The unit carries a single torque rating covering both intermittent and continuous operation, and is compatible with the Muncie EX Drive shaft extension. Three housing arrangements are available across the series. Call us to confirm the right configuration for your chassis and application.
