The Muncie SH8B-S6813-A3BX (also referenced as SH8BS6813A3BX) is an air-shift-only power take-off from Muncie's SH Series, built for high-torque truck applications that fall between the TG and 82 Series in demand. The integral air shift design keeps the air cylinder fully enclosed in the housing - no exposed cylinder to snag or corrode. The 8-bolt cast iron housing mounts securely to the transmission and supports 17 input gear sets, covering most popular transmission configurations. Five speed ratios and 12 output shaft options give this unit broad compatibility with common hydraulic pump types. Intermittent torque ratings range from 325 to 400 lb-ft depending on the selected speed ratio. Call us to confirm proper fit for your application.
