The Chelsea 871LFFJW-B5TF or 871LFFJWB5TF is a heavy-duty 871 Series Power Takeoff assembly engineered for demanding truck and vocational 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 needs, while thirteen output options accommodate a wide range of driven equipment configurations. A wet spline pump flange protects both the PTO and pump shaft during operation. Electronic Overspeed Control (EOC) guards driven equipment, and an optional SmartStart feature reduces shock load at start-up. The compact housing profile minimizes clearance conflicts during installation. Call us to confirm proper fit for your specific transmission and application.
