Sprockets don’t last forever. When they go bad, everything suffers—track wear, fuel efficiency, even machine safety. But how do you really know when it’s time to replace them? If you’re running excavators or bulldozers, recognizing sprocket wear early can save your machine and your wallet. Fulian Machinery is here to help you spot the signs and solve the problem fast.
1. Look at the Tooth Shape
Brand-new sprocket teeth have a round, symmetrical profile. Over time, wear causes the teeth to become pointed or hooked.
- Hooked teeth = serious wear
- Pointed tips = reduced contact area
- Misshaped teeth = poor engagement with the track
If the teeth no longer match the shape of the track link bushing, it’s time.
2. Listen to the Noise
A noisy undercarriage is not just annoying—it’s a red flag.
- Grinding or popping sounds?
- Irregular clicking when moving?
- That’s often caused by sprockets slipping or misaligning with the track.
Our customers often say replacing a worn sprocket immediately reduces machine noise.
3. Check for Uneven Wear
Is one side more worn than the other? That’s a problem.
- Uneven wear = poor alignment or bad installation
- Leads to premature track and roller damage
- Can strain final drive systems
Regular inspections help. We offers parts with strict dimensional tolerances to ensure perfect fit and balanced performance.

4. Look at Track Stretching
Worn sprockets stretch your tracks. When sprocket teeth don’t engage cleanly, they pull at awkward angles.
- Chain skipping
- Excessive sagging
- Premature bushing wear
Replacing a worn sprocket extends the life of your track chains by thousands of hours.
5. Inspect After 1 Track Chang
If you’ve replaced your track chains recently but kept the old sprockets, be cautious.
- New chains + old sprockets = poor match
- Increases chain wear
- Reduces machine efficiency
Fulian recommends changing sprockets every 1,000–1,200 hours or with every second track chain replacement.
