The Chelsea 871 Series Power Take-Off Assembly, part number 871XCFJP-G3XV or 871XCFJPG3XV, is a 10-bolt PowerShift (hydraulic-shift) PTO designed for Allison transmissions. The 871 Series delivers continuous-duty torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous operation. Nine speed ratios and thirteen output configurations give you broad 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 improves clamp load and reduces vibration-related damage. Optional Wet Spline pump flange, SmartStart, and Quiet Gear input are all available on this series. Call us to confirm the right configuration for your installation.
