The Muncie SH8 Series Power Take-Off, part number SH8S-M6512-A1BX or SH8SM6512A1BX, is an air-shift-only PTO engineered for high-torque applications in medium-duty truck installations. Its integral air shift design eliminates the exposed air cylinder, simplifying installation and reducing potential leak points. The 8-bolt cast iron housing mounts securely to the transmission and accommodates 17 input gear sets, covering most popular transmission bolt patterns. Five speed ratios let you match output speed to your hydraulic pump requirements, while 12 output shaft options fit most common pump types. At speed ratio 05 or 07, the SH Series is rated for up to 400 ft-lb intermittent torque (280 ft-lb continuous) at 76 HP. Call us to confirm the right configuration for your truck and pump setup.
