The Muncie SH6S-U6812-A1BX (also listed as SH6SU6812A1BX) is a medium-duty SH6 Series power take-off unit built around a 6-bolt cast iron housing with a mechanical shift design. The integral air shift keeps the air cylinder enclosed within the unit, eliminating exposed external components. Seventeen input gear sets cover most popular transmission configurations, and 12 output shaft options accommodate a wide range of pump types. Five available speed ratios give fleet operators flexibility across applications. Torque ratings vary by ratio: speed ratios 05 and 07 deliver 400 ft-lb intermittent and 280 ft-lb continuous; ratio 09 is rated at 375 ft-lb intermittent and 263 ft-lb continuous; ratios 12 and 13 are rated at 325 ft-lb intermittent and 228 ft-lb continuous. Call us to confirm proper fit for your transmission and pump setup.
