The Chelsea 871LFFJW-D5TK is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series features a compact housing that minimizes clearance issues and a ductile iron bearing cap rated 117% stronger than gray iron. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibrational stress. The series supports continuous-duty operation with torque capacity up to 670 lb-ft (908 Nm), pressure lube, and wet spline lubrication. Nine speed ratios and thirteen output options are available across the 871 Series. This PTO is sold by Pro Gear and Transmission.
