The Chelsea 871 Series Power Take-Off 871XBFJP-B3RS or 871XBFJPB3RS is a 10-bolt, hydraulic PowerShift PTO designed for Allison transmission applications. The 871 Series delivers continuous-duty torque capacity up to 670 lb-ft (908 N-m) without derating for continuous operation. Nine speed ratios and thirteen output options give this unit flexibility across fire and rescue, refuse, pumper cleaner, and truck crane installations. A ductile iron bearing cap rates 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibration-related damage. The compact housing keeps clearance issues to a minimum. The 871 Series is the only Chelsea PTO to offer all three premium options: Wet Spline, SmartStart, and Quiet Gear. Call us to confirm proper fit for your application.
