The Chelsea 871XGFJP-N5AB is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series delivers continuous torque up to 670 lb-ft (908 Nm) with no derating required for continuous-duty operation. Its compact housing minimizes clearance issues, and a ductile iron bearing cap provides 117% greater strength compared to the gray iron cap used in the predecessor 870 Series. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces the effects of engine vibration. Nine speed ratios and thirteen output options make this series adaptable across a wide range of hydraulic pump applications, including fire and rescue, truck cranes, pumper cleaners, and refuse trucks. The 871 Series also supports Wet Spline, SmartStart, and Quiet Gear options. Pro Gear and Transmission carries this genuine Chelsea part.
