A new motorcycle chain will appear to stretch during the first few rides after installation. However, a chain should not stretch too much immediately and might be defective if it continues to stretch or needs to be constantly adjusted.
What causes motorcycle chain to stretch?
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 do I stop my motorcycle chain from stretching?
The most important factor in preventing chain stretch is lubrication. If roller chains are poorly lubricated, stretching will take place very quickly. When a chain has elongated 3% of its original length, it must be replaced.
Do chains stretch over time?
Did you know that drive chain does not actually ‘stretch’? Its elongation is caused when material is removed from the pins and bushings. … As material is worn away from these surfaces, the chain will gradually elongate.
How tight should the chain be on a motorcycle?
On average, however, most street motorcycles will need a chain tension of about 20 – 30 mm, or about a half inch to an inch in slack. This means that the chain should be able to move about a half inch to an inch up and about a half inch to an inch down. It’s easiest to measure this using a measuring tape.
Do O ring chains stretch?
Technically, the chain doesn’t stretch.
How much do chains stretch?
The number most commonly agreed on for a worn chain is one percent elongation between links. In reality though, you want to replace the chain before this point. So therefore anything past 12, 1/16 inches (0.5 percent) would be the time to replace a chain.
Do chain saw chains stretch?
Chainsaw chains stretch during normal operation and begin to sag on a saw’s guide bar. If a chainsaw chain is allowed to become too loose, it can easily come off the bar during operation and create an unsafe situation for the user. Chainsaw chain tension should be checked and tightened often.
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 is the life of a motorcycle chain?
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 much does it cost to change a motorcycle chain?
How much does a bike chain cost to replace? Entry level chains can start off around $15.00 with more expensive and higher performance chains ranging from $25.00 to $60.00 or more. More expensive chains increase shift quality and are generally more durable as they wear.
How do I stop my timing chain from stretching?
It is important to have your vehicle serviced regularly for oil changes—every 5,000 miles and with the correct oil. Doing so is the best preventive maintenance of timing chain stretch and hop.
How much can a chain stretch before it rides too high on the sprocket?
The maximum allowable wear elongation is approximately 3% for most industrial applications, based upon sprocket design. The allowable chain wear in percent for large sprockets with 68 teeth or greater can be calculated using the relationship: 200/N, where N is the number of teeth in the large sprocket.
Why the chain line should properly be stretched?
Proper lubrication is critical in achieving the maximum wear life of any roller chain. As the chain articulates around the sprockets, the pin and bushing wear. This wearing causes the elongation, or “stretch,” in the chain.
