The Chelsea 871 Series Power Take-Off, part number 871XDFJP-B5BV or 871XDFJPB5BV, 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 configurations give installers broad flexibility for fire and rescue, refuse, pumper/cleaner, and truck crane applications. A ductile iron bearing cap replaces the gray iron used in the earlier 870 Series, adding 117% greater strength, while an O-ring sealing configuration between the housing and bearing cap reduces vibration-induced clamp-load loss. The Wet Spline pump flange, SmartStart, and Quiet Gear options are all available within this series. Call us to confirm the exact configuration of this specific assembly for your application.
