The Chelsea 871 Series Power Take-Off, part number 871XGFJP-D3RY or 871XGFJPD3RY, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmission applications. The 871 Series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine speed ratios and thirteen output options give installers broad flexibility across fire and rescue, refuse, pumper/cleaner, and truck crane vocations. The compact housing profile reduces clearance conflicts during installation. A ductile iron bearing cap, 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improve clamp load and counter the vibrational effects of modern engine designs. Wet Spline lubrication, SmartStart, and Quiet Gear options are all available in this series. Call us to confirm proper fitment for your specific transmission and driven equipment.
