The Muncie SH8S-M6512-E3PX or SH8SM6512E3PX is an SH Series air-shift-only power take-off built for high-torque truck applications. The SH Series was designed to fill the gap between the TG and 82 Series, pairing an 8-bolt cast iron housing with an integral air shift design that keeps the air cylinder fully enclosed. Five speed ratios cover a broad range of pump demands, and 17 input gear sets fit most popular transmissions. Twelve output shaft options make it compatible with most popular pump types. Intermittent torque ratings range from 325 to 400 lb-ft depending on the speed ratio selected. Pro Gear and Transmission carries this genuine Muncie part - call us to confirm the right ratio and output shaft configuration for your application.
