The Chelsea 871 Series Power Take-Off, part number 871XAFJP-H5XV or 871XAFJPH5XV, is a 10-bolt PowerShift (hydraulic-shift) PTO designed for Allison transmissions. The 871 Series carries a continuous torque rating up to 670 lb-ft (908 N-m), and its compact housing keeps clearance concerns to a minimum across a range of installation configurations. A ductile iron bearing cap, rated 117% stronger than gray iron, combined with an O-ring sealing configuration between the housing and bearing cap, addresses the vibrational loads generated by modern engine designs. Nine speed ratios and thirteen output options give fleet and upfitter applications wide flexibility. The 871 Series is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear as a combined option set. Call us to confirm proper fit for your specific application.
