The Chelsea 871 Series Power Take-Off Assembly, part number 871XGFJP-G3XV or 871XGFJPG3XV, is a 10-bolt PowerShift (hydraulic) PTO 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. Nine speed ratios and thirteen output options give installers broad flexibility across fire and rescue, truck crane, pumper cleaner, and refuse applications. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing the vibrational effects of modern engine designs. Optional Wet Spline pump flange, SmartStart, and Quiet Gear configurations are available within the series. Call us to confirm proper fit and option configuration for your specific application.
