The Chelsea 871 Series Power Take-Off, part number 871XAFJW-D5RY or 871XAFJWD5RY, 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 wide flexibility across fire and rescue, refuse, pumper cleaner, and truck crane applications. The ductile iron bearing cap is 117% stronger than gray iron, and an o-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. This is the only Chelsea PTO offering all three premium options together: Wet Spline, SmartStart, and Quiet Gear. Call us to confirm proper fit for your application.
