The Chelsea 871XCFJP-B3RF or 871XCFJPB3RF is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. This series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous duty use. Nine speed ratios and thirteen output options give technicians wide flexibility across fire and rescue, refuse, pumper/cleaner, and truck crane installations. 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 resisting engine vibration. The Wet Spline pump flange option protects both the PTO and pump shaft. SmartStart and Quiet Gear input options are available within the 871 Series. Call us to confirm proper fit and configuration for your specific application.
The Chelsea 871 Series replaces the earlier 870 Series PTO. If you are sourcing a replacement for an 870 Series unit, the 871 Series is the current Chelsea successor line. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's specialty options together: Wet Spline, SmartStart, and Quiet Gear. Markets served include fire and rescue, truck cranes, pumper/cleaner, and refuse. Reference documents for this series include the 267/281/288/871/878 Series Owner's Manual and the 871 Series Parts List (HY25-2871-M1/US).
