The Chelsea 878LFFJW-M3TS or 878LFFJWM3TS is a constant-mesh power take-off assembly from the 878 Series, designed to mount on Allison and CAT 10-bolt transmissions. The 878 Series carries up to 670 lb-ft continuous torque, the highest torque capability in its package class, with a single continuous-duty torque rating that eliminates the gap between intermittent and continuous use. A ductile iron bearing cap provides 117% greater strength compared to gray iron, while an O-ring sealing configuration between the housing and bearing cap improves clamp load and reduces the vibrational stress that modern engine designs produce. Rotatable cast-iron flanges reduce clearance interference, and a positive-stop driveline output protects oil seals from coupling damage. Wet spline lubrication extends shaft service life 7 to 10 times over standard configurations. The hydraulic hose is included. Call us to confirm proper fit for your application.
