The Muncie SH8D-S6809-A1CX or SH8DS6809A1CX is an SH8 Series air-shift power take-off built for high-torque truck applications. This unit uses an integral air shift design with no exposed air cylinder, mounted in an 8-bolt cast iron housing. The SH Series bridges the gap between Muncie's TG and 82 Series, offering five speed ratios and 12 output shaft options to match most common hydraulic pump configurations. Seventeen input gear sets cover the most popular transmission bolt patterns. At speed ratio 05 or 07, the unit is rated at 76 HP and 400 ft-lb intermittent torque (280 ft-lb continuous) at 1,000 RPM. Overall dimensions are 15.63 in. long x 13.38 in. wide x 11.63 in. tall. Call us to confirm the correct ratio and output shaft configuration for your application.
