The Chelsea 871 Series Power Take-Off, part number 871XHFJP-B3XV or 871XHFJPB3XV, is a 10-bolt PowerShift (hydraulic-shift) PTO designed for Allison-transmission applications. The series carries a continuous torque rating up to 670 lb-ft (908 N-m), with nine available speed ratios and thirteen output configurations to match a wide range of driven equipment. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap reduce the vibrational effects of modern engine designs. The compact housing profile limits clearance conflicts during installation. Optional Wet Spline lubrication, SmartStart shock-load reduction, Quiet Gear input, and Electronic Overspeed Control (EOC) make this one of the most configurable PTOs in the Chelsea lineup. The 871 Series replaces the earlier Chelsea 870 Series. Call us to confirm proper fit for your application.
