SH8B-U6005-A3BX Muncie Shaft Series PTO - 8-Bolt Air Shift

The Muncie SH8B-U6005-A3BX or SH8BU6005A3BX is an SH Series power take-off built for high-torque applications where the air shift mechanism must stay compact. The integral air shift design keeps the air cylinder fully enclosed inside the housing, eliminating an exposed external cylinder. The 8-bolt cast iron housing measures 11.63 in. x 13.38 in. x 15.63 in. and mounts with straightforward bolt-on installation. Five speed ratios and 12 output shaft options cover a broad range of pump types, while 17 available input gear sets allow fitment on most popular heavy-duty transmissions. Intermittent torque ratings reach 400 lb-ft at the lower speed ratios. Call us to confirm the correct ratio and output shaft configuration for your application.
