The Chelsea 871 Series Power Take-Off, part number 871XEFJP-D5BV or 871XEFJPD5BV, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. Nine speed ratios and thirteen output options cover a wide range of hydraulic pump configurations. A ductile iron bearing cap rated 117% stronger than gray iron, combined with an o-ring sealing configuration between the housing and bearing cap, directly addresses vibrational stress from modern engine designs. Optional Wet Spline pump flange, SmartStart shock-load reduction, Quiet Gear input, and Electronic Overspeed Control (EOC) make this a fit for fire and rescue, refuse, pumper cleaner, and crane truck applications. Call us to confirm the right configuration for your application.
The Chelsea 871 Series replaces the earlier 870 Series PTO. The 871 Series is the only Chelsea PTO offering all three of Chelsea's high-demand options on a single unit: Wet Spline, SmartStart, and Quiet Gear. Electronic Overspeed Control (EOC) provides added protection for driven equipment. Common markets include fire and rescue, truck cranes, pumper cleaner, and refuse trucks. Reference documents include the 871 Series Parts List (HY25-2871-M1/US) and the 267/281/288/871/878 Series Owner's Manual, available from Parker Chelsea.
