The Muncie SH8 Series Power Take-Off, part number SH8B-U6812-P3KX or SH8BU6812P3KX, is an air-shift-only PTO built for high-torque truck and vocational applications. Positioned between Muncie's TG and 82 Series, the SH8 uses an 8-bolt cast iron housing for rigid, straightforward mounting. The integral air shift design keeps the air cylinder enclosed within the unit, eliminating exposed external components. Seventeen input gear sets cover most popular transmission bolt patterns, and 12 output shaft configurations suit the widest range of pump types. Five available speed ratios deliver intermittent torque ratings from 325 to 400 lb-ft at 1,000 RPM depending on ratio selected. Call us to confirm proper fit and ratio selection for your specific transmission and pump combination.
