The Chelsea 871 Series Power Take-Off, part number 871XDFJP-D3BV or 871XDFJPD3BV, is a compact 10-bolt hydraulic PowerShift PTO designed for Allison-mounted applications. The 871 Series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine available speed ratios and thirteen output options give this unit broad application coverage across fire and rescue, truck crane, pumper cleaner, and refuse equipment. A ductile iron bearing cap - 117% stronger than gray iron - and an O-ring sealing configuration between the housing and bearing cap reduce vibration-related wear and improve clamp load. The 871 Series also supports optional Wet Spline, SmartStart, and Quiet Gear configurations. Call us to confirm proper fit for your application.
