The Muncie SH8B-U6807-E12X or SH8BU6807E12X is an SH Series air-shift power take-off built for high-torque applications. It uses an integral air-shift design with no exposed air cylinder, housed in a cast iron 8-bolt body that simplifies mounting. The unit covers 17 input gear sets to fit most popular transmissions and offers 12 output shaft options to match common pump configurations. Five speed ratios are available across the series, with intermittent torque ratings ranging from 325 to 400 lb-ft depending on the ratio selected. This PTO was designed to bridge the gap between lighter and heavier duty units where demanding hydraulic applications call for more capacity.
