The Chelsea 871XCFJP-B5RY or 871XCFJPB5RY is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty, a practical advantage on fire and rescue trucks, pumper cleaners, refuse vehicles, and truck crane installations. Nine speed ratios and thirteen output configurations cover a wide range of driven-equipment requirements. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibration-driven clamp-load loss. Optional Wet Spline pump flange, SmartStart, and Quiet Gear input round out the feature set. Call us to confirm proper fit for your application.
