The Muncie SH8S-U6812-A1EX or SH8SU6812A1EX is an SH8 Series power take-off built for high-torque applications. It uses an integral air shift design with no exposed air cylinder, mounted in an 8-bolt cast iron housing. Five speed ratios cover a wide range of drive requirements, while 17 input gear sets accommodate most popular transmission configurations. Twelve output shaft options let it pair with most common pump types. Intermittent torque ratings reach up to 400 lb-ft (542 Nm) at the two highest speed ratios, with continuous ratings up to 280 lb-ft (379 Nm). Dimensions are 11.63 in. H x 13.38 in. W x 15.63 in. L.
