The Chelsea 871XBFJP-N5SV is a 10-bolt hydraulic PowerShift Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 Nm) with no derating required for continuous duty operation. The compact housing keeps clearance issues to a minimum, and multiple assembly arrangements give installers flexibility. The 871 Series carries forward Chelsea's Wet Spline, SmartStart, and Quiet Gear options within a single PTO family. A ductile iron bearing cap rated 117% stronger than its gray iron predecessor and an o-ring sealing configuration between the housing and bearing cap improve clamp load and resist vibration. Available in nine speed ratios and thirteen output configurations.
