The Chelsea 871 Series Power Take-Off, part number 871XAFJP-G5RS or 871XAFJPG5RS, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The compact housing reduces clearance concerns, and the series supports continuous-duty operation at torque capacities up to 670 lb-ft (908 N-m). Nine speed ratios and thirteen output options make it adaptable across fire and rescue, refuse, truck crane, and pumper cleaner applications. The ductile iron bearing cap is 117% stronger than gray iron, and the O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibrational stress. The 871 Series is the only Chelsea PTO to combine Wet Spline, SmartStart, and Quiet Gear options in a single platform. Call us to confirm proper fit for your specific application.
