The Chelsea 871 Series Power Take-Off, part number 871XEFJP-D3RY or 871XEFJPD3RY, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmission applications. Continuous torque capacity reaches 670 lb-ft (908 N-m), and the 871 Series is rated for continuous-duty operation without derating. Nine speed ratios and thirteen output configurations give technicians a wide range of installation options. The compact housing lowers overall height to reduce clearance conflicts during installation. A ductile iron bearing cap, 117% stronger than gray iron, replaces the older 870 Series design, and an O-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibration-related wear. Optional Wet Spline, SmartStart, and Quiet Gear features are available within the series. This is a genuine Chelsea part sold by Pro Gear and Transmission.
