The Chelsea 871 Series Power Take-Off, part number 871XDFJP-D3AB or 871XDFJPD3AB, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous duty applications. Nine speed ratios and thirteen output options cover a wide range of installation requirements, while the compact housing keeps clearance issues to a minimum. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibration damage. Optional Wet Spline pump flange, SmartStart, Quiet Gear, and Electronic Overspeed Control (EOC) features are available within the series. The 871 Series replaces the earlier Chelsea 870 Series PTO. Call us to confirm proper fit for your specific application.
