The Chelsea 871LAFJW-B3TS or 871LAFJWB3TS is a heavy-duty Power Take-Off assembly from Chelsea's 871 Series, engineered for demanding truck hydraulic applications. Torque capacity reaches 670 lb-ft (908 N-m), supported by a ductile iron bearing cap rated 117% stronger than gray iron. Nine speed ratios cover both low and high speed demands, and thirteen output configurations give fleet spec writers real flexibility. A compact housing profile reduces clearance conflicts in tight installations. The O-ring seal configuration limits vibrational effects and maintains clamp load over service life. Electronic Overspeed Control (EOC) is available to protect driven equipment, and a SmartStart option reduces shock load at start-up. A wet spline pump flange extends PTO and pump shaft service life.
