The Chelsea 871 Series Power Take-Off assembly, part number 871XDFJP-B3SV or 871XDFJPB3SV, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 871 Series delivers continuous-duty torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous operation. A ductile iron bearing cap rated 117% stronger than gray iron and an o-ring sealing configuration between the housing and bearing cap reduce vibrational effects and improve clamp load. Nine gear ratios and thirteen output options cover a wide range of applications including fire and rescue, truck cranes, pumper cleaners, and refuse trucks. Wet Spline lubrication, SmartStart shock-load reduction, Quiet Gear input, and Electronic Overspeed Control (EOC) are all available on this series. Call us to confirm proper fit for your application.
