Description
The Muncie SH8S-U6809-E3EX (also listed as SH8SU6809E3EX) is an SH8 Series medium-duty power takeoff unit built around an 8-bolt cast iron housing. The integral air shift design keeps the air cylinder internal, eliminating exposure to road debris. Five speed ratios and 12 output shaft options cover a wide range of pump configurations, while 17 available input gear sets allow fitment to most popular heavy-duty transmissions. Continuous torque ratings range up to 280 lb-ft depending on the speed ratio selected, with intermittent ratings reaching 400 lb-ft at the 05 and 07 ratio positions. Call us to confirm the correct input gear set and output shaft configuration for your specific transmission and pump pairing.
