The Muncie SH8S-U6809-A1CX or SH8SU6809A1CX is an SH8 Series medium-duty power takeoff built around an 8-bolt cast iron housing. The integral air shift design keeps the air cylinder fully enclosed, eliminating the exposed components found on conventional units. Buyers can select from 17 input gear sets to match most popular transmission applications, and 5 speed ratios allow matching output speed to the driven equipment. Twelve output shaft options cover the most common pump configurations. Torque capacity at the top ratios reaches 400 lb-ft intermittent, stepping down to 325 lb-ft intermittent at the closer-ratio positions. Call us to confirm the correct input gear set and ratio for your specific transmission and pump combination.
