The Muncie SH8S-U6812-P3EX or SH8SU6812P3EX is a heavy-duty SH8 Series power take-off built for high-torque, air-shift-only applications. It fills the working range between Muncie's TG and 82 Series PTOs. The 8-bolt cast iron housing mounts securely and resists flex under load. The integral air shift design eliminates an exposed air cylinder, reducing the risk of damage in tight installations. Seventeen input gear sets cover most popular transmissions, and 12 output shaft options match the majority of hydraulic pump types in service. Five available speed ratios let you dial in the output your application demands. Intermittent ratings reach 76 HP and 400 lb-ft of torque at 1,000 RPM (Speed Ratios 05 and 07). Call us to confirm proper fit for your application.
