The Chelsea 871 Series Power Take-Off Assembly, part number 871XDFJP-B3BC or 871XDFJPB3BC, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The 871 Series carries continuous torque ratings up to 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output options give installers broad flexibility. The ductile iron bearing cap is 117% stronger than the gray iron predecessor, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibration damage. The compact housing profile reduces installation clearance conflicts. Optional Quiet Gear input, SmartStart shock-load reduction, Electronic Overspeed Control (EOC), and Wet Spline pump flange are available within the series. The 871 Series replaces the Chelsea 870 Series PTO. Call us to confirm the right configuration for your application.
