The Chelsea 871 Series Power Take-Off, part number 871XFQTP-B5AB or 871XFQTPB5AB, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmission applications. The series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output options give you broad flexibility across fire and rescue, truck crane, pumper cleaner, and refuse applications. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing the vibrational effects of modern engine designs. Available options include Wet Spline pump flange, SmartStart, Quiet Gear input, and Electronic Overspeed Control (EOC). 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, and refuse vehicles. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's Wet Spline, SmartStart, and Quiet Gear options on a single platform. 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 service specifications.
