The Muncie SH8S-F1113-A1KX or SH8SF1113A1KX is an SH8 Series power take-off built for high-torque applications on heavy-duty trucks. It uses an integral air shift design that eliminates an exposed air cylinder, keeping the installation compact and protected. The 8-bolt cast iron housing mounts securely to the transmission, and the unit is available with 17 input gear sets to cover most popular transmission configurations. Five speed ratios and 12 output shaft options give you flexibility to match the pump type your application requires. Intermittent torque ratings reach 400 ft-lb (542 Nm) at the lower speed ratios, with continuous ratings up to 280 ft-lb (379 Nm).
