The Chelsea 871LGFJW-D5TF is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 Nm) with no derating required for continuous duty, making it suitable for demanding applications in fire and rescue, refuse, truck cranes, and pumper cleaner equipment. Nine speed ratios and thirteen output options provide flexibility across a wide range of hydraulic and mechanical drive setups. The compact housing reduces clearance concerns during installation. A ductile iron bearing cap and o-ring sealing configuration improve clamp load and resist vibration from modern engine designs. Wet Spline, SmartStart, and Quiet Gear options are available within the 871 Series. The 871 Series replaces the Chelsea 870 Series PTO.
