The Muncie SH8B-U6809-A3ZX or SH8BU6809A3ZX is an SH8 Series power take-off built for high-torque applications where the unit must fit between the capability of lighter and heavier PTO families. Engagement is air shift only, with an integral design that eliminates an exposed air cylinder. The 8-bolt cast iron housing mounts securely to the transmission without adapters. Five speed ratios and 17 available input gear sets cover most popular transmission bolt patterns, while 12 output shaft options accommodate a wide range of pump types. Intermittent torque ratings reach up to 400 lb-ft at speed ratios 05 and 07. Call us to confirm proper fit for your specific transmission and pump combination.
