The Chelsea 871XBFJP-B5RK is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 871 Series, designed for Allison transmission applications. Continuous torque capacity reaches 670 lb-ft (908 N-m), with no derating required for continuous-duty use. Nine speed ratios and thirteen output options cover a broad range of vocational requirements including fire and rescue, refuse, truck cranes, and pumper/cleaner units. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects while improving clamp load. The compact housing minimizes clearance conflicts during installation. Optional Wet Spline pump flange, SmartStart, and Quiet Gear configurations are available within the series. Call us to confirm the exact configuration for your application.
The Chelsea 871 Series replaces the earlier 870 Series PTO. If you are sourcing a replacement for an 870 Series unit, the 871 Series is the current production successor. Applicable Parker 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.
