The Chelsea 871XCFJP-B3AB is a 10-bolt, PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. The compact housing reduces clearance issues during installation, while a ductile iron bearing cap delivers 117% greater strength than gray iron. An O-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibrational stress from modern engine designs. Nine speed ratios and thirteen output options give vocational upfitters wide flexibility. Series-rated continuous torque reaches 670 lb-ft (908 N-m). The 871 Series is the only Chelsea PTO offering all three of Chelsea's signature options: Wet Spline, SmartStart, and Quiet Gear.
