The Chelsea 871LEFJW-B3TS or 871LEFJWB3TS is a heavy-duty Power Take-Off assembly from Chelsea's 871 Series, offering a torque capacity of up to 670 lb-ft (908 N-m). The ductile iron bearing cap delivers 117% greater strength compared to gray iron. An O-ring sealing configuration reduces vibrational effects and improves clamp load retention. Nine speed ratios cover both low and high speed applications, and thirteen output configurations give this PTO broad installation flexibility. A wet spline pump flange helps extend the service life of both the PTO and pump shaft. Optional Electronic Overspeed Control (EOC) protects driven equipment, and a SmartStart option is available to reduce shock load at start-up. Call us to confirm proper fit for your specific transmission application.
