The Chelsea 871 Series Power Take-Off, part number 871XDFJW-G5RS or 871XDFJWG5RS, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 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 cover a wide range of hydraulic and mechanical applications, including fire and rescue, truck cranes, pumper cleaners, and refuse vehicles. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing the effects of engine vibration. Optional Wet Spline pump flange, SmartStart, and Quiet Gear features are available within the 871 Series. Call us to confirm proper fit for your specific transmission and application.
