The Muncie SH8B-S6809-A1BX or SH8BS6809A1BX is an SH8 Series air-shift power take-off built for high-torque applications. The 8-bolt cast iron housing mounts solidly without extra brackets, and the integral air shift design keeps the actuator internal - no exposed air cylinder to protect. Five speed ratios let you match output to the driven equipment, while 17 input gear sets cover most popular transmission bolt patterns and 12 output shaft options accommodate a wide range of pump types. Torque capacity varies by speed ratio: intermittent ratings run from 325 to 400 lb-ft and continuous ratings from 228 to 280 lb-ft, depending on the ratio selected. Call us to confirm proper fit for your application.
