The Muncie SH8D-S6812-P3CX or SH8DS6812P3CX is an SH Series air shift power take-off built for high-torque applications. The integral air shift design eliminates any exposed air cylinder, keeping installation clean and mounting straightforward on its 8-bolt cast iron housing. Five speed ratios cover a wide range of drive requirements, and 12 output shaft options accommodate most popular pump types. Seventeen input gear sets means this PTO fits most popular transmissions. Intermittent torque ratings across the five speed ratios range from 325 to 400 lb-ft, with continuous torque ratings from 228 to 280 lb-ft. Dimensions are 11.63 in. H x 13.38 in. W x 15.63 in. L.
