The Muncie SH8B-U6812-A1IX or SH8BU6812A1IX is an SH Series power take-off built for high-torque truck applications. This unit uses an integral air shift design with no exposed air cylinder, keeping the assembly compact and protected. The 8-bolt cast iron housing simplifies mounting and delivers the structural strength required for demanding service. With 17 input gear sets available, the SH Series fits most popular transmissions, and 12 output shaft options cover the majority of common pump types. Five speed ratios provide flexibility across a range of hydraulic system requirements. Rated up to 76 HP and 400 lb.ft. intermittent torque at 1,000 RPM (depending on ratio selected). Call us to confirm proper fit for your application.
