The Muncie SH8B-U6812-E1EX (also referenced as SH8BU6812E1EX or MUSH8BU6812E1EX) is an SH8 Series power take-off built for high-torque applications. It uses an integral air shift design with no exposed air cylinder, keeping the unit compact and protected. The 8-bolt cast iron housing simplifies mounting and holds up under demanding duty cycles. Five speed ratios and 17 input gear sets give this PTO broad transmission compatibility across most popular models. Twelve output shaft options let it drive most common pump types. Intermittent torque ratings range from 325 to 400 lb-ft depending on the selected speed ratio. Call us to confirm proper fit for your transmission and output shaft requirements.
