The Chelsea 871 Series Power Take-Off, part number 871LHFJW-B5TY or 871LHFJWB5TY, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmission applications. The 871 Series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine available speed ratios and thirteen output options cover a wide range of hydraulic pump configurations. 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 while reducing vibration-related wear. Optional Wet Spline, SmartStart, and Quiet Gear features make this the only Chelsea PTO to offer all three of those solutions. Call us to confirm the right configuration for your application.
