Description
The Chelsea 871 Series Power Take-Off Assembly, part number 871XDFJP-G5XV or 871XDFJPG5XV, is a 10-bolt, PowerShift (hydraulic) PTO designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. Nine speed ratios and thirteen output options give installers broad flexibility across fire and rescue, refuse, truck crane, and pumper/cleaner truck builds. 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 effects of engine vibration. Wet Spline, SmartStart, and Quiet Gear options are all available within this series. Call us to confirm the correct configuration for your specific application.
