The Muncie SH8B-U6807-E3ZX (also referenced as SH8BU6807E3ZX or MUSH8BU6807E3ZX) is an 8-bolt cast iron SH Series air-shift power take-off built for high-torque applications. The integral air shift design keeps the air cylinder fully enclosed inside the housing, eliminating the exposed-cylinder failure points common on older designs. Five speed ratios and 17 input gear sets give this unit broad transmission compatibility, while 12 output shaft options accommodate most popular hydraulic pump interfaces. Overall dimensions are 11.63 in. H x 13.38 in. W x 15.63 in. L. Intermittent torque ratings reach up to 400 lb.-ft. depending on the speed ratio selected. Available from Pro Gear and Transmission.
