The Chelsea 871XBFJP-B3RK or 871XBFJPB3RK is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmissions. The series delivers continuous torque up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. Nine speed ratios and thirteen output options give this unit broad application flexibility across fire and rescue, refuse, truck crane, and pumper cleaner work. A ductile iron bearing cap (117% stronger than gray iron) and an O-ring sealing configuration between the housing and bearing cap resist vibrational damage from modern engine designs. Optional Wet Spline, SmartStart, and Quiet Gear features are available within the 871 Series. The 871 Series replaces the Chelsea 870 Series PTO. Call us to confirm proper fit and configuration for your specific application.
