The Muncie SH8D-S6812-P3PX (also referenced as SH8DS6812P3PX) is an SH8 Series power take-off built for high-torque applications. It features an integral air shift design with no exposed air cylinder, housed in an 8-bolt cast iron body that measures 11.63 in. H x 13.38 in. W x 15.63 in. L. Five speed ratios cover a wide range of drive requirements, while 17 input gear sets allow fitment across most popular transmissions. Twelve output shaft options accommodate the most common pump configurations. Torque ratings vary by speed ratio, with intermittent torque reaching up to 400 lb-ft and continuous torque up to 280 lb-ft at the top speed ratio settings. A genuine Muncie part available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
