The Muncie SH8S-U6809-A3PX or SH8SU6809A3PX is an SH8 Series medium-duty power take-off built around an 8-bolt cast iron housing and an integral air shift design that keeps the air cylinder fully enclosed. Seventeen input gear sets cover most popular transmission bolt patterns, while 5 available speed ratios and 12 output shaft options give this PTO broad compatibility across pump types. Intermittent torque ratings reach 400 lb-ft (542 Nm) at the two highest-ratio positions, stepping down to 325 lb-ft (441 Nm) at the closer-ratio settings. Continuous torque ratings range from 228 to 280 lb-ft (309-379 Nm) depending on the ratio selected. Available from Pro Gear and Transmission.
