The Chelsea 871 Series Power Take-Off, part number 871XHFJP-B5RK or 871XHFJPB5RK, is a 10-bolt hydraulic PowerShift PTO designed for Allison-mounted applications. The compact housing keeps clearance issues to a minimum, and the ductile iron bearing cap is 117% stronger than gray iron. An O-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibrational effects caused by modern engine designs. The series supports nine speed ratios and thirteen output configurations, giving you the flexibility to match a wide range of vocational needs. Three specialty options are available on this series: Wet Spline pump flange for extended PTO and pump shaft life, SmartStart to reduce shock load at start-up, and Quiet Gear input. Continuous-duty operation is supported up to 670 lb-ft of torque. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The 871 Series replaces the earlier 870 Series PTO. It is the only Chelsea PTO to offer all three of Chelsea's specialty solutions in a single platform: Wet Spline, SmartStart, and Quiet Gear. Markets served by this series include fire and rescue, truck cranes, pumper cleaner, and refuse applications. Refer to Chelsea application pages for actual torque ratings specific to your installation. Part number 871XHFJP-B5RK is also referenced as SP871XHFJP-B5RK in some catalog listings. Parker documents covering this series include the 267/281/288/871/878 Series Owner's Manual and 871 Series Parts List HY25-2871-M1/US.
