Wear on the undercarriage sprockets

When are the sprockets on my mini-excavator or excavator worn out? Find out here how to recognize wear on the undercarriage sprockets and determine for yourself whether replacement is needed.

Tooth wear

The rule of thumb here is: the thinner and more pointed the teeth, the more worn the sprockets are. On a new sprocket, the tips of the teeth are approximately 10 mm to 15 mm thick. When the sprockets are 100% worn, the tooth thickness is reduced to 1 mm.

It's not only the thickness of the teeth that indicates wear on the undercarriage sprockets, but also their height; if the teeth have become too low, there is a high probability that the chain or rubber track will not engage properly with the sprocket. A steel chain or rubber track will then simply slip over the sprocket, causing additional wear on the track bushings.

Cracked or broken sprocket

In addition to the standard - and recognizable - wear and tear on undercarriage sprockets, other patterns of damage may necessitate replacement. Repeated exposure to the same type of impact can eventually lead to metal fatigue. Initially, this may manifest as the appearance of surface cracks. At a later stage, these cracks can develop into major fractures, potentially causing pieces of the sprocket to break off completely.
