The Chelsea 871LEFJW-B3TK or 871LEFJWB3TK is a 871 Series Power Take-Off assembly built for demanding hydraulic and mechanical drive applications. Torque capacity reaches 670 lb-ft (908 N-m), and the series offers nine speed ratios covering both low and high speed ranges plus thirteen output configurations, giving spec managers real flexibility across vehicle and pump setups. A ductile iron bearing cap, rated 117% stronger than gray iron, handles the structural load, while an O-ring sealing configuration reduces the effects of vibration and improves clamp load retention. A wet spline pump flange helps extend both PTO and pump shaft service life. Electronic Overspeed Control (EOC) protects driven equipment, and a SmartStart option is available for applications where shock load at start-up is a concern. Call us to confirm proper fit for your transmission and application.
