The Chelsea 871XAFJW-N5RY is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 Nm) with no derating required for continuous duty operation. Nine available speed ratios and thirteen output options give this series exceptional application flexibility. The compact housing design reduces clearance concerns during installation, and multiple assembly arrangements support a wide range of mounting configurations. The ductile iron bearing cap is 117% stronger than gray iron, and an o-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibration. The 871 Series is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear options within a single platform.
