The Chelsea 871 Series Power Take-Off, part number 871XGFJP-H5AC or 871XGFJPH5AC, is a 10-bolt PowerShift (hydraulic-shift) PTO designed for Allison transmissions. The series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine speed ratios and thirteen output options give builders wide flexibility for fire and rescue, refuse, truck crane, and pumper-cleaner applications. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Optional Wet Spline pump flange, SmartStart, and Quiet Gear configurations are available within the 871 Series. The 871 Series replaces the earlier Chelsea 870 Series PTO. Call us to confirm proper fit for your application.
