The Chelsea 871LBFJW-B5TF is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Its compact housing reduces clearance concerns during installation, and multiple assembly arrangements allow flexible mounting configurations. 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 helps control vibration. Wet spline lubrication (pressure lube) is included to extend PTO and pump shaft service life. Pro Gear and Transmission carries this genuine Chelsea part.
