The Chelsea 871LAFJW-B5TY or 871LAFJWB5TY is a heavy-duty 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 along with thirteen output configurations. A ductile iron bearing cap provides 117% greater strength than gray iron, and an O-ring sealing configuration reduces vibrational effects while improving clamp load retention. The compact housing height minimizes clearance concerns during installation. Available options include Quiet Gear input, SmartStart shock-load reduction, Electronic Overspeed Control (EOC), and a wet spline pump flange that extends both PTO and pump shaft service life. Call us to confirm proper fit for your transmission and application.
