The Muncie SH8D-S6809-A3PX or SH8DS6809A3PX is an SH8 Series power take-off built specifically for high-torque air-shift applications. The integral air shift design keeps all shift components internal, eliminating any exposed air cylinder. The 8-bolt cast iron housing provides a rigid, straightforward mounting path, and the unit spans 17 input gear sets to cover most popular transmission applications. Five speed ratios are available within the series, and 12 output shaft options accommodate most common hydraulic pump configurations. At speed ratio 05 or 07, the unit is rated at 76 HP and 400 ft-lb intermittent torque (280 ft-lb continuous). Call us to confirm proper fit for your transmission and pump setup.
