What issue can cause the chain to ride high on the teeth of a sprocket in a chain drive?

The issue of a chain riding high on the teeth of a sprocket can indeed be attributed to insufficient tension in the chain. When the chain lacks adequate tension, there is not enough force to properly engage the teeth of the sprocket, which can lead to the chain sitting higher than normal. This misalignment can cause erratic movement, increased wear on both the chain and sprockets, and a higher likelihood of the chain jumping off the sprocket altogether during operation.

Proper chain tension is essential for ensuring that the chain makes full contact with the teeth, which promotes effective power transmission and helps maintain the overall health of the drive system. Adjusting the tension to the manufacturer's specifications is crucial for optimal performance and longevity of the chain drive.
