The Chelsea 871XAFJP-N5AC is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, engineered for Allison transmission applications. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 Nm) with no derating required for continuous-duty use. Its compact housing keeps clearance issues to a minimum, and the ductile iron bearing cap is 117% stronger than the gray iron cap used on predecessor units. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibrational effects. Nine speed ratios and thirteen output options cover a wide range of hydraulic pump configurations. The 871 Series also supports Wet Spline, SmartStart, and Quiet Gear options, making it one of the most versatile Chelsea PTO platforms available. Common markets include fire and rescue, truck cranes, pumper cleaner, and refuse trucks. Available from Pro Gear and Transmission.
