The Muncie SH8D-S6812-E1ZX or SH8DS6812E1ZX is an air-shift-only power take-off from Muncie's SH8 Series, built to handle high-torque applications that fall between lighter-duty and heavier-series PTOs. The 8-bolt cast iron housing simplifies mounting and delivers structural strength in demanding service. An integral air shift design keeps the air cylinder enclosed, eliminating exposed components. With 17 input gear sets, this PTO fits most popular transmission configurations, and 12 output shaft options accommodate a wide range of pump types. Five available speed ratios let you match output to your specific drive requirements. The series torque ratings reach up to 400 ft-lb intermittent and 280 ft-lb continuous at the two highest speed ratios. Call us to confirm proper fit for your application.
