The Chelsea 871 Series Power Take-Off, part number 871XDFJW-B3RS or 871XDFJWB3RS, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The compact housing keeps clearance issues to a minimum, and the ductile iron bearing cap delivers 117% greater strength than gray iron. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces the damaging vibrational effects associated with modern engine designs. Nine speed ratios and thirteen output options give you broad flexibility across demanding applications including fire and rescue, refuse, truck cranes, and pumper cleaners. Continuous torque capacity reaches 670 lb-ft (908 N-m). The 871 Series also supports Chelsea's Wet Spline, SmartStart, and Quiet Gear options, making it the only Chelsea PTO to offer all three. Call us to confirm proper fit for your application.
