Is your motorcycle sprocket showing signs of wear and tear such as cracks, dents, or chipped teeth? In this case, you need to replace it as soon as possible. Keep in mind that once this part breaks down, the movement and performance of the chain is greatly reduced. So don't be surprised if you experience strange vibrations around the foot peg area once this component bites the dust. Fortunately, changing a sprocket or sprocket-wheel is an easy task as long as you have the right tools and basic repair skills. To help you out, here's what you need to do to get your motorcycle sprocket up and running:
Tools you'll need:
- New tab washers
- Paddock stand
- Torque wrench
Step 1: Prep your vehicle against the paddock stand.
To steady the motorcycle, prop it up against a paddock stand. Make sure that your motorcycle is standing on level ground.
Step 2: Remove the sprocket cover.
To do this, you need to loosen the wheel nut first with a socket. Once the nut is removed, you'll have easy access to the cover. In some cases, you might have to remove the gear lever in order to uninstall the cover. If this is the case, make sure to mark the linkage clamp and the gear shaft's end to make re-installation easier.
Step 3: Gain access to the motorcycle sprocket.
Before you start with this step, keep in mind that the right removal technique will depend on whether you're dealing with a front or rear sprocket. For a front type, you either have to remove the central nut and tab washer with a socket or flatten the washer to gain access to the nuts. After gaining access to the sprocket, stop it from moving by holding the spokes against the swingarm by using a piece of wood. If it's a rear sprocket, the process is more straightforward since you just need to uninstall the rear wheel to get access to the bolting nuts.
Step 4: Remove the sprocket.
When removing the front type, undo the chain adjusters and place the wheel forward until the chain becomes slack. You should then be able to lift off the sprocket. As for its rear counterpart, you simply have to unbolt the nuts in order to remove it.
Step 6: Attach the new motorcycle sprocket.
Attach the new sprocket to the shaft and secure it in place with a new tab washer. Same thing goes for the rear sprocket-wheel. Once the sprocket-wheels are in place, you can now re-attach the wheels. Tighten the bolts with a torque wrench, following the torque specifications of your motorcycle's manufacturer.
Things to keep in mind:
- When you're replacing the sprockets, it's also advisable to replace the chains. This is because you want your motorcycle sprocket and chain to wear out at around the same time.
- After the installation, don't forget to squirt some lube on the new chains and sprockets to keep them in top shape for a long time.
