The Muncie SH8B-U6812-A1EX (also referenced as SH8BU6812A1EX) is an SH8 Series air-shift power take-off built for high-torque applications. It uses an integral air shift design with no exposed air cylinder, keeping the installation compact and clean. The 8-bolt cast iron housing mounts securely to the transmission, and 17 available input gear sets cover most popular transmission applications. Five speed ratios let you match output to your hydraulic system, while 12 output shaft options fit most common pump types. Intermittent torque ratings vary by speed ratio, reaching up to 400 lb-ft (542 Nm) at the 05 and 07 ratios at 1,000 RPM. Call us to confirm proper fit and gear ratio selection for your application.
