The original BMW swing arm bolt 3-020, made of hardened steel, rotatably mounts the swing arm of the BMW Isetta front axle and reliably transmits the driving and braking forces that occur. During restoration, it is recommended to replace worn or corroded pins to prevent play in the bearing, noise, and spongy handling. This ensures precise wheel alignment and allows the Isetta’s front axle to function again in its intended original condition.
