The Chelsea 871XHFJP-D5AC is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 Nm) and does not require derating for continuous-duty operation. Its compact housing is engineered to minimize clearance conflicts during installation, and multiple assembly arrangements give installers flexibility in tight spaces. The ductile iron bearing cap is 117% stronger than 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. The 871 Series supports nine speed ratios and thirteen output options, and is the only Chelsea PTO line to offer Wet Spline, SmartStart, and Quiet Gear options within a single series. Common markets include fire and rescue, refuse, truck cranes, and pumper cleaner applications. Part number 871XHFJP-D5AC is sold by Pro Gear and Transmission.
