The Muncie A20-A1010-HR3CBPW or A20A1010HR3CBPW is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees, giving installers flexibility in tight engine compartments, and the extended-length PTO mounting fasteners and increased housing clearance simplify the installation process. Tapered roller bearings protect the output shaft under load, while the enlarged output shaft diameter adds durability at the wheel end. The design carries a single intermittent/continuous torque rating and is available in three housing arrangements, making it adaptable across a range of truck body and hydraulic applications. Compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
