    Sometimes the machine’s sprockets or segments are sharp, but the track links appear to be in reasonable condition. We are frequently asked whether the sprockets still need to be changed. The only reason why a sprocket becomes sharp is through the chain’s increased pitch. An increase in pitch creates more play between the pin and the bushing. As a result, the chain’s bushing no longer runs in line with the hollow part of the sprocket. This causes wear on the sprockets and the points become sharp. So never only replace a sprocket. If a track drive sprocket from an excavator with dry chains needs to be replaced, then the track links should always be replaced as well, and vice versa.
