The Muncie SH8B-U6809-P3IX (also referenced as SH8BU6809P3IX) is an SH Series air-shift power take-off built for high-torque truck applications. This unit fills the gap between lighter and heavier PTO series with an integral air shift design that eliminates an exposed air cylinder, reducing potential leak points. The 8-bolt cast iron housing mounts securely to the transmission. Five speed ratios and 17 input gear sets give it wide transmission compatibility, while 12 output shaft options accommodate most common hydraulic pump configurations. Intermittent torque ratings reach 400 lb-ft (542 Nm) at the two highest speed ratios. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
