The Chelsea 871XGFJP-N5AC is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series delivers continuous-duty torque capacity up to 670 lb-ft (908 Nm) without derating, and is available in nine speed ratios with thirteen output options including SAE B, SAE BB, and SAE C pump spline configurations as well as companion flange outputs. A ductile iron bearing cap, 117% stronger than gray iron, and an o-ring sealing configuration between the housing and bearing cap improve clamp load and reduce vibration effects. The compact housing minimizes clearance concerns during installation, and multiple assembly arrangements expand mounting possibilities. Common applications include fire and rescue, truck cranes, pumper/cleaner units, and refuse vehicles.

Additional Information
The 871 Series replaces the Chelsea 870 Series PTO. Upgrades over the 870 Series include the ductile iron bearing cap and o-ring sealing configuration. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's high-demand options: Wet Spline, SmartStart, and Quiet Gear. SmartStart reduces shock load at start-up for demanding applications. Electronic Overspeed Control (EOC) protects driven equipment from overspeed events. Applicable Parker Chelsea documentation includes the 267/281/288/871/878 Series Owner's Manual, the 871 Series Parts List (HY25-2871-M1/US), and the 871 Series Sales Literature.Parts Manual: Chelsea 871 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
