The Chelsea 871 Series Power Take-Off Assembly, part number 871XFFJP-D5XV or 871XFFJPD5XV, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The compact housing is engineered to reduce clearance issues, and the ductile iron bearing cap is 117% stronger than gray iron. An O-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibrational effects from modern engine designs. The 871 Series supports continuous duty operation with torque capacity up to 670 lb-ft (908 N-m) across nine speed ratios and thirteen output options. Optional features include Wet Spline pump flange, SmartStart for shock load reduction, Quiet Gear input, and Electronic Overspeed Control (EOC). Call us to confirm proper fit for your application.
