The Muncie SH8 Series Power Take-Off, part number SH8S-U6809-A3ZX or SH8SU6809A3ZX, is an air-shift-only PTO built for high-torque applications. It fills the performance gap between the Muncie TG and 82 Series. The integral air shift design keeps the air cylinder fully enclosed inside the housing, protecting it from road debris and contamination. The 8-bolt cast iron housing mounts securely and holds up to sustained output demands. With 17 input gear sets available across the SH Series, this PTO fits most popular transmission configurations, and 12 output shaft options accommodate a wide range of hydraulic pump types. Five speed ratios let you match PTO output to the specific hydraulic circuit requirement. Call us to confirm proper fitment for your transmission and pump combination.
