The Muncie SH8B-U6812-E1PX or SH8BU6812E1PX is an SH Series power take-off built for high-torque applications. It uses an integral air shift design with no exposed air cylinder, keeping the unit compact and protected in tight installations. The 8-bolt cast iron housing makes mounting straightforward and holds up under demanding duty cycles. With 17 input gear sets, this PTO fits most popular transmissions, and 12 output shaft options accommodate a wide range of pump types. Five speed ratios give you flexibility across applications. Torque ratings vary by ratio: speed ratios 05 and 07 carry 400 ft-lb intermittent and 280 ft-lb continuous; ratio 09 is rated 375 ft-lb intermittent and 263 ft-lb continuous; ratios 12 and 13 are rated 325 ft-lb intermittent and 228 ft-lb continuous. Call us to confirm proper fit for your transmission and pump configuration.
