This bearing housing secures the bearing assembly on the right side of the header driveline. It positions the rotating shaft that transmits power to the header auger or reel, maintaining alignment under load. A worn housing allows shaft misalignment, leading to vibration and accelerated bearing failure. This component matches the original housing geometry, so the bearing seats correctly and the retaining bolts align with the existing mounting holes. On reinstall, clean the mounting face and torque the retaining bolts to specification.
