The Muncie SH8 Series Power Take-Off, part number SH8S-U6812-P1PX or SH8SU6812P1PX, is an air-shift-only PTO built for high-torque applications. It bridges the gap between Muncie's TG and 82 Series, offering five speed ratios and 12 output shaft options to suit most hydraulic pump configurations. The 8-bolt cast iron housing simplifies mounting and delivers structural strength, while the integral air shift design eliminates an exposed air cylinder. Seventeen input gear sets allow fitment across most popular heavy-duty transmission platforms. Intermittent torque ratings range from 325 to 400 lb-ft depending on speed ratio selected. Call us to confirm proper fit for your transmission and pump setup.
