The Muncie SH8B-S6812-A1BX or SH8BS6812A1BX is an SH8 Series power take-off built for high-torque applications, positioned between the TG and 82 Series in Muncie's lineup. Its integral air shift design keeps the air cylinder internal, eliminating exposed components. The 8-bolt cast iron housing simplifies mounting and holds up in demanding service. Five available speed ratios cover a wide range of driven equipment needs, while 17 input gear sets accommodate most popular transmission configurations and 12 output shaft options match most common pump types. Intermittent torque ratings reach 400 ft-lb (542 Nm) at speed ratios 05 and 07. Call us to confirm the right ratio and output shaft configuration for your truck and pump setup.
