The Chelsea 871 Series Power Take-Off, part number 871XDFJP-B5RZ or 871XDFJPB5RZ, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmission applications. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty, making it a practical fit for fire and rescue, refuse, pumper cleaner, and truck crane work. Nine speed ratios and thirteen output options give installers the flexibility to match a wide range of pump and equipment requirements. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibration-related wear. Optional Wet Spline, SmartStart, and Quiet Gear configurations are available within the series. This part supersedes the Chelsea 870XDFJP-B5RZ or 870XDFJPB5RZ.
