Using this axle is straightforward. First, select the appropriate hardness based on your needs. If you're using it with an outboard drive for a 100cc engine like Yamaha, IAME, or ROK, or a shifter inboard axle drive, just make sure to choose the right axle key. It also fits LO206 Briggs engines well. When installing, handle it carefully to avoid any damage. For maintenance, keep it clean and check for any signs of wear regularly. Store it in a dry place to prevent rust. If you notice any issues, replace the axle as soon as possible to ensure safe and efficient operation.
