The Muncie SH8 Series Power Take-Off, part number SH8S-U6807-M1KX or SH8SU6807M1KX, is an air-shift-only PTO engineered for high-torque applications. Its integral air shift design eliminates an exposed air cylinder, keeping the unit compact and well-protected. The 8-bolt cast iron housing mounts securely to the transmission without complex fabrication. Seventeen input gear sets cover most popular transmission configurations, and 12 output shaft options accommodate a wide range of pump types. Five speed ratios let you match output to the specific hydraulic demand of your application. Series torque ratings reach up to 400 ft-lb intermittent and 280 ft-lb continuous at certain ratios.
