The Muncie SH8S-U6812-E1SX or SH8SU6812E1SX is an SH8 Series air-shift power take-off built for high-torque applications. The integral air shift design keeps the air cylinder internal, eliminating exposed components that can be damaged in field use. The 8-bolt cast iron housing simplifies mounting and delivers the structural strength that demanding hydraulic applications require. With 17 input gear sets available across the SH Series, this PTO fits most popular heavy-duty transmissions. Five speed ratios give flexibility across different pump and application requirements, and 12 output shaft options cover the most common pump types. Intermittent torque ratings range from 325 to 400 lb-ft depending on the speed ratio selected. Call us to confirm proper fit for your application.
