The Chelsea 871 Series Power Take-Off, part number 871XBFJP-B5RZ or 871XBFJPB5RZ, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The 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 broad range of vocational requirements, including fire and rescue, truck crane, refuse, and pumper cleaner work. The ductile iron bearing cap is 117% stronger than gray iron, and the O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibrational effects from modern engine designs. Optional Wet Spline pump flange, SmartStart, and Quiet Gear configurations are available within the series. The compact housing height keeps clearance issues to a minimum. Call us to confirm proper fit and configuration for your specific application.
The 871 Series replaces the Chelsea 870 Series PTO. It is the only Chelsea PTO to offer all three of the following options within a single platform: Wet Spline pump flange for extended PTO and pump shaft life, SmartStart for reduced shock load at start-up, and Quiet Gear input. Electronic Overspeed Control (EOC) is also available to protect driven equipment. Typical vocational markets include fire and rescue, truck cranes, refuse collection, and pumper cleaner trucks. Applicable reference documents include the 871 Series Parts List (HY25-2871-M1/US) and the 267/281/288/871/878 Series Owner's Manual published by Parker Chelsea.
