The Chelsea 871 Series Power Take-Off, part number 871XJFJP-B3XV or 871XJFJPB3XV, is a 10-bolt hydraulic PowerShift PTO designed for demanding continuous-duty applications on Allison-transmission-equipped vehicles. Torque capacity reaches 670 lb-ft (908 N-m), and the series offers nine speed ratios and thirteen output options to match a wide range of hydraulic system requirements. A ductile iron bearing cap rated 117% stronger than gray iron, combined with an O-ring sealing configuration between the housing and bearing cap, directly addresses the vibrational stress produced by modern engine designs. Optional Wet Spline lubrication protects the pump flange and output shaft, while the optional SmartStart feature reduces shock load at start-up. Electronic Overspeed Control (EOC) is also available to safeguard driven equipment. The compact housing keeps clearance concerns to a minimum in tight cab-to-axle installations. Common markets include fire and rescue, refuse, truck cranes, and pumper-cleaner equipment. Call us to confirm proper fit for your application.
