The Muncie SH8B-U6812-P1CX or SH8BU6812P1CX is an SH8 Series air-shift power take-off built for high-torque truck applications. The integral air-shift design keeps the air cylinder fully internal, eliminating exposed hardware. The 8-bolt cast iron housing mounts securely to the transmission, and 17 available input gear sets cover most popular transmission configurations. Five speed ratios give you the flexibility to match output speed to your pump requirement, while 12 output shaft options accommodate most common pump types. At speed ratio 05 or 07, the SH8 series is rated for up to 400 ft-lb intermittent torque and 280 ft-lb continuous torque. Call us to confirm the right configuration for your transmission and pump.
