When to replace a chain

Here are a few maintenance tips to help extend the life of your chain:

  1. When replacing chain, always inspect the corresponding sprockets. Be sure to replace any worn sprockets to avoid shortening the life of your new chain.
  2. For best performance, keep the chain tension on the slack span within 4 to 6 percent of the span length.
  3. As chain wears, it becomes longer. The normal maximum chain-wear elongation is around 3 percent, after which time, you should replace the chain to avert greater maintenance problems.

By following these simple tips, you'll know the right time to replace your chain without causing additional damage to other drive components.
