The Chelsea 871 Series PTO Assembly, part number 871XFQTP-B3XV or 871XFQTPB3XV, is a heavy-duty power take-off unit rated for up to 670 lb-ft (908 N-m) of torque. The ductile iron bearing cap is rated 117% stronger than gray iron, and an O-ring seal configuration reduces the effects of vibration while improving clamp load. Nine speed ratios cover both low and high speed applications, and thirteen output configurations give drivetrain builders real flexibility. The compact housing height helps where clearance is tight. A wet spline pump flange protects both the PTO and pump shaft. Electronic Overspeed Control (EOC) and an optional SmartStart feature are available for equipment-protection and shock-load reduction. Call us to confirm proper fit for your specific application.
