The Chelsea 878XBFJW-M3RS or 878XBFJWM3RS is a 10-bolt constant mesh Power Take-Off assembly built around a cast iron housing. Its ductile iron bearing cap is rated 117% stronger than gray iron, and an O-ring sealing configuration reduces the effects of vibration while improving clamp load. Nine speed ratios cover both low and high speed requirements, and a single continuous duty torque rating simplifies spec matching. Rotatable cast-iron flanges reduce interference fitting issues, and driveline outputs include a positive-stop feature that eliminates oil seal damage from coupling contact. A Wet Spline Lubrication option extends shaft life by 7 to 10 times compared to standard dry splines. The hose is included with the assembly.
