Look closely at the sprocket teeth to see if they have become sharp at the tips and/or slightly curled. The teeth on a new sprocket are straight and have a flat or domed shape at the tip. If the teeth are sharp, the sprocket is worn.
What happens if chain sprocket is damaged?
If the teeth are worn bad enough the chain may not roll off the sprocket as it turns. This could cause the wheel to lock up and result in a uncontrolable skid. The lack of chain tension could also cause the chain to fall off and jam in the drive train. You might ruin the wheel or damage the engine and transmission.
What is the likely consequence of riding a motorcycle with a worn drive chain?
As the chain and sprockets wear the chain will get loose. Eventually, you will run out of adjustment to take up that slack. When the chain is too loose, it will jump teeth and possibly fall off the sprocket completely.
What is the life of chain sprocket?
As everyone suggested, it depends on your riding style and frequency of your maintenance. But as per my experience with proper lubing & optimum chain slack, the approximate life of the chain sprocket should be 20k to 25k kms.
Why is my motorcycle chain tight and loose?
A motorcycle chain that keeps getting loose is usually caused by the rear axle or chain tensioning bolts not being tight enough. It can also be cause by a new chain not being worn in enough, worn down sprocket teeth, having too tight of a tension, or having the wrong size of chain installed.
How often should a motorcycle chain be lubed?
every 300-600 miles
A motorcycle chain should be lubricated every 300-600 miles to ensure peak performance and a long life. Lubricate the chain after riding, not before. This allows time for the solvents in the spray to evaporate before the bike is used again, and lets the lubricant penetrate the link properly.
Why are sprockets worn out?
As we noted, when roller chain elongates, the distance between rollers increases. This phenomenon affects how the chain wraps around the sprocket. When functioning correctly, the roller will fall into the gullet between teeth and then roll off of the driving side of the sprocket tooth.
How long does motorcycle chain and sprocket last?
But chains wear out over time and need replacing. So, how often should a motorcycle chain be replaced? In general, a properly maintained motorcycle can last 20,000 to 30,000 miles, sometimes more. But, some last as little as 5,000 to 10,000 miles.
How do you maintain a chain sprocket?
The chain cleaning and lubrication should be done every 500 to 700kms, depending on the usage. If your bike ends up in the dirt every time you are back from a ride, then you should do it more often at around 500 -600 kms. If you do not off-road, or your roads are comparatively cleaner on the chain set.
What happens if motorcycle chain is too loose?
If the chain is too slack, it can skip over the tooth in the sprockets, This skipping over of teeth leads to uneven transmission of power from the engine to the wheel. As a result, the speed of the motorcycle will unevenly oscillate without any intervention from the rider.
What happens if motorcycle chain is tight?
When a motorcycle chain is too tight, it’ll put stress on several components of the bike and cause the sprockets to wear faster, make the engine work harder, and cause the suspension to be tight and uncomfortable. Ultimately, a tight chain on a motorcycle may break leaving you with no power.
How does a front sprocket work on a motorcycle?
Both sprockets have teeth which slot into the gaps in the motorcycle’s drive chain. The sprockets work in tandem with their teeth engaging between the drive chain links. The front sprocket rotates at the same time as the engine’s transmission output shaft, and the teeth pull the drive chain,…
How do I know when to replace my chain or sprocket?
If the teeth on a sprocket have become sharpened or ‘hooked’ at the tip instead of being blunted, they need to be replaced. You can tell if your chain is worn by pushing up on the chain in the middle with one hand while pulling on it at the rear sprocket.
How do I know if my rear sprocket is bad?
Inspect the sprocket’s teeth. They should not be arched on one side, like a cresting wave. If it is, you need to replace the sprocket, and your chain is probably toast, too. At the far back end on the rear sprocket, pull the chain away from the teeth parallel to the ground.
Should the chain width match the sprocket width on a motorcycle?
The chain width should always match the sprocket width. One of the advantages of chain drive over other forms of final drive in motorcycles is that chains and sprockets make it easy to change the overall gearing.
