The Muncie SH8S-M6507-A3ER (also referenced as SH8SM6507A3ER) is an air-shift-only power take-off from the Muncie SH Series, engineered for high-torque applications where the standard TG Series falls short. The 8-bolt cast iron housing mounts cleanly to the transmission without exposed air cylinder hardware, keeping the installation compact. Five speed ratios cover a wide range of pump speed requirements, and 17 input gear sets extend compatibility across the most common transmission configurations. With 12 output shaft options, it suits the majority of pump interfaces without adaptation. For intermittent duty at speed ratio 05 or 07, the series is rated at 400 lb-ft torque and 76 HP at 1,000 RPM. Call us to confirm the correct ratio and output shaft combination for your application.
