The Chelsea 871 Series Power Take-Off, part number 871XDFJP-L5BC or 871XDFJPL5BC, is a 10-bolt PowerShift (hydraulic shift) PTO designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. Nine speed ratios and thirteen output configurations give installers broad flexibility to match pump and driven-equipment requirements. The compact housing minimizes clearance conflicts in tight installations. A ductile iron bearing cap, rated 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap address vibrational stress from modern engine designs. Optional features include Quiet Gear input, SmartStart shock-load reduction, Wet Spline pump flange, and Electronic Overspeed Control (EOC). The 871 Series replaces the Chelsea 870 Series.
