Using this WildKart floating sprocket hub outer aluminum plate is easy. First, make sure you have the right Wild Kart NEW STYLE floating sprocket hub. Remove the old outer plate if there is one. Then, align the new plate with the 6 - bolt pattern on the hub and secure it tightly. When it comes to maintenance, keep the plate clean from dirt and debris. Check the bolts regularly to ensure they are tight. Don't use this plate with other non - compatible sprocket hubs. Also, remember that this is just a replacement part, so you need to buy the sprocket hub separately if you don't have one already.
