- Remove the Chain: If your minibike already has a sprocket installed, you’ll need to remove the chain first. Use your socket wrench to loosen the rear wheel axle nut on one side. Once it’s loose, use your locking pliers or vice grips to hold the chain in place and prevent it from moving. Then, remove the axle nut and slide the rear wheel slightly forward to create slack in the chain. Once you have enough slack, remove the chain from the sprocket.
- Remove the Old Sprocket: Use your socket wrench or ratchet to remove the bolts or nuts holding the old sprocket in place. Typically, there will be three or four of these bolts around the sprocket. Once they’re removed, you can take off the old sprocket.
- Install the New Sprocket: Place the new minibike sprocket onto the rear wheel hub in the same orientation as the old sprocket. Make sure it lines up with the bolt holes on the hub. Insert the bolts or nuts through the sprocket and into the hub. Tighten them securely using your socket wrench or ratchet.
- Resize the Chain (if necessary): If the new sprocket has a different number of teeth than the old one, you may need to resize your chain to fit the new sprocket. Use a chain breaker tool to remove any excess links from the chain until it fits snugly on the new sprocket without excessive slack.
- Reinstall the Chain: Slide the chain back onto the new sprocket, making sure it engages properly with the teeth. If you had to resize the chain, make sure it’s properly connected using the master link or a connecting link, depending on the type of chain you have.
- Adjust Chain Tension: Adjust the rear wheel position to tension the chain correctly. You want the chain to have a little bit of slack but not be too loose. Check your minibike’s manual for the recommended chain tension.
- Tighten Axle Nut: Once you have the chain tension set correctly, tighten the rear wheel axle nut on one side using your socket wrench.
