The Chelsea 871XAFJP-G3XV or 871XAFJPG3XV is a 10-bolt PowerShift (hydraulic) Power Take-Off Assembly from the 871 Series, designed for Allison transmissions. The 871 Series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine speed ratios and thirteen output options give this PTO broad versatility 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. Wet Spline, SmartStart, and Quiet Gear options are all available in this series. Call us to confirm proper fit and configuration for your specific application.
