The Chelsea 871 Series Power Take-Off Assembly, part number 871XDFJP-D3RY or 871XDFJPD3RY, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty applications. Nine available speed ratios and thirteen output options give this unit a wide application range covering fire and rescue, truck cranes, pumper/cleaner trucks, and refuse vehicles. 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 loads produced by modern engine designs. This is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear options in a single platform. Call us to confirm proper fit for your specific transmission and installation.
