The Muncie SH8S-M6509-A3QX (also referenced as SH8SM6509A3QX) is an SH8 Series power take-off built for high-torque, air-shift-only applications. It fills the gap between the TG and 82 Series with an integral air shift design that eliminates the exposed air cylinder. The 8-bolt cast iron housing simplifies mounting and handles demanding duty cycles. Seventeen input gear sets cover most popular transmission configurations, while 12 output shaft options accommodate most pump types. Five available speed ratios let you match output to the hydraulic system at hand. Series torque ratings reach up to 400 ft-lbs intermittent and 280 ft-lbs continuous depending on the selected speed ratio. Call us to confirm proper fit for your application.
