The Muncie SH8B-U6812-M3PX or SH8BU6812M3PX is an SH Series power take-off built for high-torque applications, filling the gap between Muncie's TG and 82 Series. The integral air shift design keeps the air cylinder fully enclosed inside the housing, eliminating the exposed cylinder common to other designs. The 8-bolt cast iron housing mounts without special adapters on most popular transmissions, supported by 17 input gear set options. Five speed ratios let you match output to the pump demand, and 12 output shaft configurations cover most common pump types. Intermittent torque ratings range from 325 to 400 lb-ft depending on the ratio selected. Call us to confirm the right ratio and shaft configuration for your specific application.
