The Muncie SH8B-U6809-A3PX (also referenced as SH8BU6809A3PX) is an SH8 Series air-shift power take-off built for high-torque applications. It fills the range between lighter-duty and heavier series PTOs with an integral air shift design that keeps the air cylinder fully enclosed inside the housing, eliminating exposed external components. The 8-bolt cast iron housing mounts securely to the transmission. With 17 available input gear sets, this series covers most popular transmission configurations, and 12 output shaft options give flexibility across common pump types. Five speed ratios let you match output speed to your specific hydraulic or mechanical requirement. Call us to confirm proper fit for your transmission and application.
