The Chelsea 871 Series Power Take-Off, part number 871XGFJP-D3BC or 871XGFJPD3BC, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications, making it a practical fit for fire and rescue apparatus, truck cranes, pumper cleaners, and refuse vehicles. Nine speed ratios and thirteen output options give you the flexibility to match the PTO to a wide range of driven equipment. The ductile iron bearing cap is 117% stronger than gray iron, and the o-ring sealing configuration between housing and bearing cap reduces vibrational effects and improves clamp load. The 871 Series is also the only Chelsea PTO to offer all three of Chelsea's signature options: Wet Spline, SmartStart, and Quiet Gear.
