The Chelsea 871XEFJP-B3XV or 871XEFJPB3XV is a ten-bolt PTO assembly engineered for demanding hydraulic and driveline applications. The 871 Series delivers torque capacity up to 670 lb-ft (908 N-m) and offers nine speed ratios covering both low and high speed ranges, plus thirteen output configurations to match a wide variety of pump and driveline setups. A ductile iron bearing cap rated 117% stronger than gray iron adds durability at the gear interface. The improved O-ring sealing configuration reduces vibrational effects and improves clamp load retention. A wet spline pump flange extends service life on both the PTO and pump shaft. Electronic Overspeed Control (EOC) and the optional SmartStart feature are available to protect driven equipment and reduce shock loads at start-up.
