The Chelsea 871XCFJW-B3RY or 871XCFJWB3RY is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. Continuous torque capacity reaches 670 lb-ft (908 N-m), and the unit supports continuous-duty operation without derating. Nine available speed ratios and thirteen output options give installers broad flexibility across fire and rescue, truck crane, pumper cleaner, and refuse truck builds. A ductile iron bearing cap rated 117% stronger than gray iron handles the vibration demands of modern engine designs, while an O-ring sealing configuration between the housing and bearing cap improves clamp load. The compact housing height reduces clearance issues in tight installations. Call us to confirm proper fit for your specific transmission and application.
The 871 Series is the only Chelsea PTO to offer all three of Chelsea's primary drive-protection options on a single platform: Wet Spline (extends PTO and pump shaft life), SmartStart (reduces shock load at start-up), and Quiet Gear input. Electronic Overspeed Control (EOC) is also available to protect driven equipment. Common markets for this series include fire and rescue apparatus, truck cranes, pumper cleaner trucks, and refuse vehicles. Applicable Parker documents include the 267/281/288/871/878 Series Owner's Manual and the 871 Series Parts List (HY25-2871-M1/US).
