The Chelsea 871XHFJP-B3RF is a 10-bolt, hydraulic PowerShift Power Take-Off from Chelsea's 871 Series, designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 Nm) with no derating required for continuous-duty operation. Its compact housing reduces clearance issues compared to larger units, and a ductile iron bearing cap provides significantly improved structural strength over gray iron designs. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibration-related wear. The 871 Series also supports Wet Spline, SmartStart, and Quiet Gear options across its product range. Part number 871XHFJP-B3RF is sold by Pro Gear and Transmission.
