The Chelsea 871 Series Power Take-Off, part number 871XHFJP-D3AC or 871XHFJPD3AC, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmission applications. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine speed ratios and thirteen output options give this unit a wide range of installation flexibility, while a compact housing profile reduces clearance conflicts during installation. 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 the vibrational effects of modern engine designs. The 871 Series is the only Chelsea PTO to offer all three of the brand's high-demand options: Wet Spline, SmartStart, and Quiet Gear. Common markets include fire and rescue, truck cranes, pumper-cleaner, and refuse. Call us to confirm proper fitment for your specific transmission and application.
