The Muncie SH8 Series Power Take-Off, part number SH8B-U6807-A1BX or SH8BU6807A1BX, is an air-shift-only PTO built for high-torque applications. The integral air shift design keeps the air cylinder fully enclosed within the housing, eliminating an exposed cylinder. The 8-bolt cast iron housing mounts solidly and accommodates 17 input gear sets, covering most popular transmission applications. Five available speed ratios let you match output to your pump requirements, and 12 output shaft options support most common pump types. At speed ratio 05 or 07, the series is rated for up to 400 lb-ft intermittent torque and 280 lb-ft continuous torque at 1,000 RPM. Call us to confirm the correct gear set and output shaft configuration for your specific truck and pump setup.
