The Chelsea 871 Series Power Take-Off, part number 871XDFJP-D3SV or 871XDFJPD3SV, is a 10-bolt hydraulic PowerShift PTO 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 configurations give installers a wide range of speed and interface options to match the application. The compact housing keeps overall height low, reducing clearance conflicts during installation. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap address the vibrational loads common in modern engine designs. Optional Wet Spline pump flange, SmartStart, and Quiet Gear input are all available on this series. Call us to confirm proper fit for your application.
