The Chelsea 871 Series Power Take-Off, part number 871XFFJW-B3RS or 871XFFJWB3RS, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The series delivers continuous-duty torque capacity up to 670 lb-ft (908 N-m), with no derating required for continuous operation. Nine speed ratios and thirteen output options cover a wide range of application requirements, including fire and rescue, refuse, truck crane, and pumper cleaner work. A ductile iron bearing cap rated 117% stronger than gray iron pairs with an O-ring sealing configuration between housing and bearing cap to reduce vibrational effects and improve clamp load. The compact housing profile limits clearance conflicts during installation. Wet Spline lubrication, SmartStart, and Quiet Gear options are available on this series.
