The Muncie SH8B-U6809-P3EX (also referenced as SH8BU6809P3EX) is an SH Series power take-off from Muncie Power Products, engineered specifically for high torque applications that fall between lighter-duty and heavy-duty PTO ranges. The integral air shift design keeps the air cylinder fully enclosed within the housing, eliminating external cylinder exposure and simplifying installation. The 8-bolt cast iron housing mounts solidly to the transmission and resists flex under load. With 17 input gear set options, the SH Series fits most popular transmission models, while 5 available speed ratios and 12 output shaft configurations allow close matching to the hydraulic pump at hand. A genuine Muncie part, available from Pro Gear and Transmission. Call us to confirm the correct ratio and output shaft configuration for your specific application.
Features
Air shift only design with integral, enclosed air cylinder - no exposed external cylinder
8-bolt cast iron housing for rigid mounting and structural strength
17 input gear set options cover most popular transmission applications
5 speed ratios available across the SH Series for output matching flexibility
12 output shaft configurations to suit most common hydraulic pump interfaces
Positioned between the Muncie TG and 82 Series for mid-range high torque demands
