Wear on the sides of a chain typically indicates which issue?

Wear on the sides of a chain can be a sign of several underlying issues, which is why the most comprehensive answer is that it indicates all of the listed possibilities. When a chain experiences excessive side wear, it typically suggests that there is a misalignment or obstruction affecting the chain’s movement and engagement with the sprockets.

Sprocket misalignment is a significant contributor to side wear because when the sprockets are not aligned properly, the chain does not run true through the sprockets. This leads to uneven contact along the chain’s links and can wear away the material on the sides over time.

Additionally, shaft misalignment can also cause misalignment of the sprockets, leading to the same side wear issues. When the shafts supporting the sprockets are not in line with each other, it alters the path the chain takes, promoting sideways movement against the sprocket teeth.

Obstruction is another factor that can cause chains to wear on the sides. If something obstructs the chain’s path or interrupts its intended movement, it can cause the chain to rub against elements it typically would not contact, leading to increased wear.

By acknowledging that all three issues can contribute to side wear on a chain, it paints a complete picture of potential
