The Muncie SH8S-M6509-A1EX or SH8SM6509A1EX is an SH8 Series power take-off built for high-torque applications, filling the gap between lighter-duty and heavier series PTOs. It uses an integral air shift design with no exposed air cylinder, keeping the installation compact and the actuator protected. The 8-bolt cast iron housing mounts securely and handles the mechanical stress of demanding hydraulic work. With 17 input gear sets, 5 speed ratios, and 12 output shaft options, the SH8 covers most popular transmission and pump combinations. Intermittent torque ratings reach up to 400 lb-ft at speed ratios 05 and 07, with continuous ratings up to 280 lb-ft. Call us to confirm proper fit for your transmission and pump setup.
