The Muncie SH8 Series Power Take-Off, part number SH8B-U6812-A3CX or SH8BU6812A3CX, is an air-shift-only PTO built for high-torque applications. It fills the gap between the TG and 82 Series in the Muncie lineup. The integral air shift design keeps the air cylinder fully enclosed inside the housing, eliminating an exposed external cylinder. The 8-bolt cast iron housing simplifies mounting and handles the structural demands of heavy-duty service. Seventeen input gear sets cover most popular transmission applications, while 12 output shaft options accommodate the most common pump types. Five available speed ratios let you match output to the hydraulic circuit. Call us to confirm the correct ratio and output shaft configuration for your specific installation.
