The Muncie SH8D-S6812-A3EX or SH8DS6812A3EX is an air-shift-only power take-off from Muncie Power's SH Series, engineered for high-torque applications that fall between the TG and 82 Series in output demand. The integral air shift design keeps the air cylinder fully enclosed inside the housing, eliminating an exposed external cylinder. The 8-bolt cast iron housing mounts securely to the transmission and accepts one of 17 input gear sets, covering most popular transmission configurations. Five speed ratios deliver versatility across duty cycles, and 12 output shaft options accommodate most common pump types. Peak intermittent ratings across the series range from 62 to 76 HP at 1,000 RPM depending on ratio selected. Call us to confirm proper fit and ratio selection for your application.
