The Muncie SH8D-S6812-A1BX or SH8DS6812A1BX is an SH8 Series medium-duty power take-off with an integral air shift design that keeps the air cylinder completely enclosed within the housing. The 8-bolt cast iron housing mounts solidly to the transmission without external cylinder exposure. With 17 input gear sets available, this PTO is engineered to fit a wide range of popular transmission configurations, and 12 output shaft options cover the most common hydraulic pump interfaces. Five speed ratios let the installer match PTO output to specific pump demands. Intermittent torque ratings reach up to 400 lb-ft depending on the selected ratio, with continuous torque up to 280 lb-ft. Call us to confirm proper fit for your transmission and application.
