The Chelsea 871 Series Power Take-Off, part number 871XDFJP-D5XV or 871XDFJPD5XV, is a 10-bolt hydraulic PowerShift 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 operation. Its compact housing minimizes clearance issues in tight installations, and nine speed ratios with thirteen output configurations give installers wide flexibility. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between housing and bearing cap reduces vibrational effects while improving clamp load. The Wet Spline pump flange extends both PTO and pump shaft service life. SmartStart and Quiet Gear options are available to suit fire and rescue, refuse, pumper, and truck crane applications. Call us to confirm proper fit for your application.
The Chelsea 871 Series replaces the earlier 870 Series PTO. All 871 Series improvements focus on reducing the damaging vibrational effects associated with modern engine designs. This is the only Chelsea PTO to offer all three of Chelsea's high-demand options: Wet Spline, SmartStart, and Quiet Gear. Common markets include fire and rescue, refuse, pumper-cleaner, and truck crane applications. Reference documents for this series include the 267/281/288/871/878 Series Owner's Manual, the 871 Series Parts List (HY25-2871-M1/US), and 871 Series Sales Literature.
