The Muncie SH8 Series power take-off, part number SH8S-U6809-E3ZX or SH8SU6809E3ZX, is an air-shift-only PTO built for high-torque applications. The integral air shift design keeps the air cylinder fully enclosed within the housing, eliminating exposed components. The 8-bolt cast iron housing mounts securely to the transmission, and 17 available input gear sets cover most popular transmission configurations. Five speed ratios and 12 output shaft options give this unit broad compatibility across pump types. At speed ratio 05 or 07, intermittent torque capacity reaches 400 lb-ft (542 Nm), with continuous torque rated at 280 lb-ft (379 Nm).
