The Chelsea 871XFKVP-B3SV or 871XFKVPB3SV is a 10-bolt hydraulic PowerShift Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty use. Nine speed ratios and thirteen output options cover a wide range of application requirements. 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 of modern engine designs. Optional Wet Spline pump flange, SmartStart, and Quiet Gear configurations are available within the series. This is the only Chelsea PTO line to offer all three of those features. The 871 Series replaces the earlier Chelsea 870 Series. Call us to confirm proper fit for your application.
