The Chelsea 871 Series Power Take-Off, part number 871XGFJP-B5AB or 871XGFJPB5AB, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmission applications. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine speed ratios and thirteen output options cover a wide range of driven-equipment requirements, from fire and rescue pumpers to refuse and crane trucks. A ductile iron bearing cap rated 117% stronger than gray iron, combined with an o-ring sealing configuration between the housing and bearing cap, addresses the vibrational demands of modern engine designs. Optional Wet Spline pump flange, SmartStart, and Quiet Gear configurations are available within the 871 Series. The 871 Series replaces the Chelsea 870 Series PTO.
