The Muncie SH8S-U6812-E3BX (also referenced as SH8SU6812E3BX) is an SH8 Series power take-off built for high-torque, air-shift-only applications. Its integral air shift design keeps all air cylinder components internal, eliminating exposed hardware on the housing. The 8-bolt cast iron housing simplifies mounting and holds up under demanding duty cycles. Seventeen input gear sets cover most popular transmissions, and 12 output shaft options accommodate most common pump types. Five available speed ratios let you match PTO output to the specific hydraulic circuit. Torque ratings reach 400 ft-lb intermittent and 280 ft-lb continuous at the 05 and 07 speed ratios. Call us to confirm proper fit for your transmission and output shaft requirements.
