The Muncie SH8B-U6807-A3EX or SH8BU6807A3EX 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, resulting in a compact installation with no exposed cylinder hardware. Five speed ratios cover a range of drive requirements, with intermittent torque ratings reaching 400 ft-lb (542 Nm) at speed ratios 05 and 07, stepping to 375 ft-lb (508 Nm) at ratio 09 and 325 ft-lb (441 Nm) at ratios 12 and 13. Seventeen input gear sets allow fitment across most popular transmissions, and 12 output shaft options match most common pump configurations. Overall dimensions are 11.63 in. H x 13.38 in. W x 15.63 in. L. Pro Gear and Transmission carries this genuine Muncie part. Call us to confirm proper fit for your application.
