The Muncie SH8D-S6812-A3PX or SH8DS6812A3PX is an air shift power take-off from Muncie Power's SH Series, engineered to bridge the gap between the TG and 82 Series for high-torque truck applications. The integral air shift design keeps the air cylinder fully enclosed within the housing, eliminating exposed components. The 8-bolt cast iron housing simplifies mounting and delivers structural strength. With 17 input gear sets available across the SH Series, this PTO covers most popular transmission configurations, and 12 output shaft options accommodate a wide range of pump types. Five available speed ratios let you match PTO output to application requirements. Call us to confirm proper fit for your specific transmission and pump configuration.
