The Chelsea 871 Series Power Take-Off Assembly, part number 871XDFJP-G5RS or 871XDFJPG5RS, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. 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 speed ratios and thirteen output options give this unit broad application flexibility across fire and rescue, truck crane, pumper/cleaner, and refuse equipment. A ductile iron bearing cap, rated 117% stronger than gray iron, pairs with an O-ring sealing configuration between the housing and bearing cap to combat vibrational stress from modern engine designs. Optional Wet Spline, SmartStart, and Quiet Gear configurations are available within this series. This unit also cross-references to 870XDFJP-G5RS or 870XDFJPG5RS and 3131PGE633RJ.
