The Chelsea 871 Series Power Take-Off, part number 871LCFJW-B3TS or 871LCFJWB3TS, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. Continuous-duty rated at up to 670 lb-ft (908 N-m) of torque, it needs no derating for sustained operation. The compact housing reduces clearance conflicts during installation. Nine speed ratios and thirteen output options cover a wide range of hydraulic applications including fire and rescue apparatus, truck cranes, pumper-cleaner units, and refuse vehicles. The ductile iron bearing cap is 117% stronger than gray iron, and the o-ring sealing configuration between housing and bearing cap improves clamp load while reducing damage from engine vibration. Call us to confirm proper fit for your specific chassis and transmission configuration.

The 871 Series replaces the earlier Chelsea 870 Series PTO and incorporates upgraded sealing, bearing, and lubrication features. It is the only Chelsea PTO to offer all three high-demand options together: Wet Spline, SmartStart, and Quiet Gear. Common application markets include fire and rescue, truck cranes, pumper-cleaner, and refuse vehicles. Refer to the 871 Series Parts List (HY25-2871-M1/US) and the 267/281/288/871/878 Series Owner's Manual for full application and installation details.
