The Chelsea 878LEFJW-M5TS or 878LEFJWM5TS is a constant mesh Power Take-Off assembly from the Chelsea 878 Series, engineered to mount on Allison 10-bolt transmissions. 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 the damaging vibrational effects of modern engine designs. Rotatable, cast-iron flanges reduce interference clearance issues, and the positive-stop driveline output eliminates oil seal damage from coupling contact. The wet spline lubrication option extends shaft life by 7 to 10 times compared to dry-spline configurations. A hydraulic hose is included -- no need to order separately. Call us to confirm proper fit for your specific application.
