The Chelsea 871 Series Power Take-Off, part number 871XDFJP-B3RZ or 871XDFJPB3RZ, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmission applications. The 871 Series carries continuous torque ratings up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine speed ratios and thirteen output options cover a wide range of installation requirements, while the compact housing minimizes clearance conflicts. A ductile iron bearing cap, 117% stronger than gray iron, pairs with an O-ring sealing configuration between the housing and bearing cap to resist the vibrational stress of modern engine designs. Optional Wet Spline pump flange, SmartStart, and Quiet Gear configurations are available within the series. Call us to confirm proper fit and configuration for your application.
