The Muncie SH8B-U6809-A3IX or SH8BU6809A3IX is an 8-bolt, air-shift power take-off from the Muncie SH8 Series, designed to fill the torque gap between lighter and heavier PTO families. The integral air shift mechanism keeps all components internal with no exposed air cylinder, reducing vulnerability to road debris and simplifying the mounting envelope. The cast iron 8-bolt housing mounts directly to most popular transmission interfaces, supported by 17 input gear set options. Five speed ratios let you match output speed to the pump, and 12 output shaft configurations cover most common pump types. Intermittent torque ratings reach 400 lb.ft. at the two most aggressive speed ratios. Call us to confirm proper fit for your specific transmission and pump combination.
