The Chelsea 871XAFJP-G3RS or 871XAFJPG3RS is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 871 Series, designed for Allison transmission applications. The 871 Series delivers continuous-duty torque up to 670 lb-ft (908 N-m) with nine available speed ratios and thirteen output configurations. A ductile iron bearing cap provides 117% greater strength than gray iron, while an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. The compact housing minimizes clearance concerns, and the wet spline pump flange helps extend PTO and pump shaft service life. Optional SmartStart reduces shock load at start-up, and Electronic Overspeed Control (EOC) safeguards driven equipment. Call us to confirm the right configuration for your application.
The 871 Series is the only Chelsea PTO to offer all three of Chelsea's high-demand solutions in a single platform: Wet Spline, SmartStart, and Quiet Gear. The 871 Series also replaces and upgrades the earlier Chelsea 870 Series. Applicable markets include fire and rescue, truck cranes, pumper cleaners, and refuse vehicles. Related 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.
