The Chelsea 871LAFJW-B3TZ or 871LAFJWB3TZ is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. A ductile iron bearing cap, 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improve clamp load and resist vibration caused by modern engine designs. Nine speed ratios and thirteen output options give this PTO broad application flexibility. The 871 Series is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear options together.
