Are your chain’s pins rotating?
One of the easier ways to check and see if your chain needs to be replaced is to inspect the quad staked pins on your chain. When a chain is new all the pins will be all aligned and will be parallel. As a chain ages, loses internal lubrication and the internal components start wearing down, the pins can start rotating as seen in the image here. If you have pin rotation on your chain you should replace the chain ASAP.
As a preventative measure, frequent lubrication can delay the onset of rotated pins. For non-sealed chains, internal lubricant can be somewhat replaced by directing the l**e towards the roller and bushing areas on both sides so that the pin will be protected and lubricated. Unfortunately for sealed chains replacing the internal lubricant is not possible.
