The Muncie SH Series power take-off, part number SH8B-U6809-E1GX or SH8BU6809E1GX, is an air-shift-only PTO built for high-torque truck applications. The integral air shift design eliminates any exposed air cylinder, keeping the unit compact and well-protected. The 8-bolt cast iron housing mounts securely to most popular transmission cases, and 17 available input gear sets cover a wide range of transmission makes. Five speed ratios let you match output to your pump's demand, while 12 output shaft options accommodate the most common hydraulic pump interfaces. Intermittent torque ratings reach 400 ft-lb at speed ratios 05 and 07, stepping to 375 ft-lb at ratio 09 and 325 ft-lb at ratios 12 and 13. Pro Gear and Transmission carries this genuine Muncie unit.
