The Chelsea 871XCFJP-N5AC is a 10-bolt, hydraulic PowerShift Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. The 871 Series features a compact housing that reduces clearance concerns and a ductile iron bearing cap rated 117% stronger than gray iron. An o-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibrational stress. The series supports continuous-duty operation with torque capacity up to 670 lb-ft (908 Nm) and offers nine speed ratios across thirteen output options. Wet Spline, SmartStart, and Quiet Gear configurations are available within this series. Pro Gear and Transmission carries genuine Chelsea parts for demanding vocational applications.
