The Chelsea 871XBFJP-B3RY or 871XBFJPB3RY is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. The 871 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 cover a wide range of vocational requirements including fire and rescue, refuse, truck crane, and pumper-cleaner work. 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 reducing vibration-related wear. Wet Spline, SmartStart, and Quiet Gear options are available on this series. Call us to confirm the exact configuration and proper fit for your application.
