The Chelsea 871XFFJP-B5RY or 871XFFJPB5RY is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from the 871 Series, designed for Allison transmission applications. 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 give this unit a wide fit across fire and rescue, truck crane, pumper cleaner, and refuse 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. Wet Spline, SmartStart, and Quiet Gear options are all available on the 871 Series. Call us to confirm proper fit for your specific Allison transmission configuration.
