The Chelsea 871 Series Power Take-Off, part number 871XDFJP-B5SV or 871XDFJPB5SV, is a 10-bolt PowerShift (hydraulic) PTO engineered for Allison transmissions. The 871 Series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Its compact housing minimizes clearance issues, and a ductile iron bearing cap delivers 117% greater strength than gray iron. An O-ring sealing configuration between housing and bearing cap reduces vibrational effects and improves clamp load. Nine speed ratios and thirteen output options make this unit adaptable across fire and rescue, refuse, truck crane, and pumper-cleaner applications. The 871 Series is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear options together. Call us to confirm proper fit for your application.
The Chelsea 871 Series replaces the earlier 870 Series PTO. Applicable Parker documents include 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. Typical markets include fire and rescue, refuse, truck cranes, and pumper-cleaner vehicles.
