The Muncie SH8 Series Power Take-Off, part number SH8M-U6809-E1EX or SH8MU6809E1EX, 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 protected. The 8-bolt cast iron housing mounts securely to the transmission and delivers the structural strength demanding vocational duty cycles require. With 17 available input gear sets, this SH8 Series unit covers most popular transmission configurations. Five speed ratios let you match output to your hydraulic system, and 12 output shaft options accommodate most common pump interfaces. Rated up to 76 HP and 400 ft-lb intermittent torque at 1,000 RPM in the lower speed ratios. Call us to confirm the right input gear set and output shaft for your specific application.
