The Chelsea 871XGFJP-D3AC or 871XGFJPD3AC is a 10-bolt PowerShift (hydraulic) Power Take-Off built for Allison transmissions. Part of Chelsea's 871 Series, this compact unit delivers continuous-duty torque capacity up to 670 lb-ft (908 N-m) across nine speed ratios with thirteen output options. 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 while reducing the effects of modern engine vibration. Pressure lube and Wet Spline pump flange lubrication are available, extending PTO and pump shaft service life. The 871 Series also supports Quiet Gear input and SmartStart options for shock-sensitive applications. Electronic Overspeed Control (EOC) is available to protect driven equipment.
