The Muncie SH8S-M6512-A1CX or SH8SM6512A1CX is an SH8 Series power take-off built for high-torque, air-shift-only applications. It uses an 8-bolt cast iron housing for secure, straightforward mounting and an integral air shift design that eliminates exposed air cylinders. Five speed ratios give flexibility across different drive requirements, and 17 input gear sets cover most popular transmissions. Twelve output shaft options make it compatible with a wide range of pump types. Intermittent torque ratings across the five speed ratios range from 325 to 400 lb-ft at 1,000 RPM, with continuous ratings from 228 to 280 lb-ft. Call us to confirm proper fitment for your transmission and pump configuration.
