The Chelsea 871XGFJP-H5XV or 871XGFJPH5XV is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmissions. The series supports continuous torque up to 670 lb-ft (908 N-m) with no derating required for continuous duty applications. Nine speed ratios and thirteen output configurations cover a wide range of hydraulic drive setups. 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 profile minimizes clearance conflicts on tighter installations. The 871 Series is the only Chelsea PTO offering all three of their high-demand options together: Wet Spline, SmartStart, and Quiet Gear. Chelsea's 871 Series supersedes the earlier 870 Series. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
The 871 Series supersedes the Chelsea 870 Series PTO. Compatible options on this series include Wet Spline pump flange for extended PTO and pump shaft life, SmartStart for reduced shock load at startup, Quiet Gear input, and Electronic Overspeed Control (EOC) for protection of driven equipment. Typical markets served by the 871 Series include fire and rescue, truck cranes, pumper cleaner, and refuse vehicles.
