How do I know when my Sprockets are worn?

A worn Sprocket on your excavator can cause significant damage to the other undercarriage components - especially the tracks.

How do I check the wear on the Sprockets?

Although accelerated wear on the sprockets is not common, it is essential that this component should be checked often for signs of damage or wear. To check the wear on a Sprocket the main area to check is the teeth that engage with the track on your machine. If the Sprocket is worn, the teeth will be more pointed and sharp whereas a good Sprocket will have more rounded teeth. This is shown in the two examples below.

It is especially important to check the Sprockets when changing the tracks on your machine. A worn sprocket will accelerate wear on the track links and cause your tracks to wear in significantly less time. We would always recommend to change your sprockets when you fit a new set of tracks to your machine as not only does this save the time and cost of fitting them but also will prevent premature wear and extend the up-time of your excavator.
