The Chelsea 871XBFJP-B3XV or 871XBFJPB3XV is a ten-bolt PTO assembly built for heavy-duty truck hydraulic applications. Torque capacity reaches 670 lb-ft (908 N-m), with nine available speed ratios covering both low and high ranges and thirteen output options for broad pump compatibility. The ductile iron bearing cap is rated 117% stronger than gray iron, and the housing is designed with a reduced height to minimize clearance conflicts at install. An O-ring sealing configuration controls vibrational effects and maintains clamp load at the cover joint. Optional features on the 871 platform include Quiet Gear input, SmartStart shock-load reduction, and Electronic Overspeed Control (EOC) for driven-equipment protection. A wet spline pump flange extends service life at the PTO-to-pump interface. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your transmission and application.
