The Chelsea 871LGFJW-B5TS or 871LGFJWB5TS is a 10-bolt hydraulic PowerShift Power Take-Off from the 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 work, making it a practical choice for fire and rescue, refuse, pumper/cleaner, and truck crane applications. A ductile iron bearing cap, 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap address the vibrational stress common in modern engine designs. Nine speed ratios and thirteen output options give installers broad flexibility, and the series supports Wet Spline, SmartStart, and Quiet Gear options. Call us to confirm proper fit for your specific transmission and application.
The 871 Series replaces the earlier Chelsea 870 Series PTO. Typical markets include fire and rescue, truck cranes, pumper/cleaner units, and refuse vehicles. The series is unique among Chelsea PTOs in offering all three premium options, Wet Spline, SmartStart, and Quiet Gear, on a single platform. Electronic Overspeed Control (EOC) is available to protect driven equipment from damaging overspeed events. Refer to Parker document 871 Series Parts List (HY25-2871-M1/US) and the 267/281/288/871/878 Series Owner's Manual for full installation and parts information.
