The Chelsea 871 Series Power Take-Off Assembly, part number 871XHFJP-G5XV or 871XHFJPG5XV, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. This unit carries a gear ratio of 34/30 and a continuous torque capacity of up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. The compact housing minimizes clearance issues during installation, and the ductile iron bearing cap delivers 117% greater strength than gray iron. An O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. The 871 Series supersedes the Chelsea 870 Series and also cross-references as 870XHFJP-G5XV or 870XHFJPG5XV. Call us to confirm proper fit for your application.
The Chelsea 871 Series is the only Chelsea PTO to offer all three premium options in a single platform: Wet Spline pump flange for extended PTO and pump shaft life, SmartStart to reduce shock load at start-up, and Quiet Gear input for noise-sensitive applications. Electronic Overspeed Control (EOC) is also available to protect driven equipment. The 871 Series serves markets including fire and rescue, truck cranes, pumper cleaners, and refuse vehicles. Refer to Parker Chelsea application pages for actual torque ratings specific to your installation.
