This washer sits under the hexagon-head gearbox support bolt, spreading load and providing a smooth, vibration-resistant surface between the bolt head and the support bracket. It ensures that the gearbox support bearing bracket is held securely to the chassis or transmission housing, helping maintain correct gearbox alignment and reducing the risk of loosening under engine and drivetrain load
