The Chelsea 871XBFJW-D3RS is a 10-bolt PowerShift (hydraulic shift) Power Take-Off Assembly from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. The compact housing is engineered to minimize clearance conflicts at installation, and 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 resists vibration from modern engine designs. The 871 Series also supports Wet Spline, SmartStart, and Quiet Gear options. Call us to confirm proper fitment and assembly arrangement for your application.
