What Does the Sprocket Do?
The chain sprocket transfers rotational power from the engine through the clutch to the saw chain. The chain's drive links engage with the sprocket teeth, allowing the chain to travel around the guide bar.
A properly matched sprocket is important for smooth chain movement and correct chain engagement.
Signs Your Sprocket May Need Replacement
Inspect the sprocket if you notice:
-
Worn or hooked sprocket teeth.
-
Excessive tooth wear.
-
Uneven wear patterns.
-
Chain movement that feels rough or inconsistent.
-
Premature chain wear.
-
A chain that does not engage the sprocket correctly.
A heavily worn sprocket should be replaced to help prevent damage to the chain and maintain proper operation.
Installation Note
Before replacing the sprocket:
-
Shut off the chainsaw and allow all moving components to stop.
-
Remove the appropriate chain-brake and clutch-area components according to the applicable service procedure.
-
Inspect the sprocket and surrounding clutch components.
-
Replace the worn sprocket with the 1129 640 2050 6T Picco.
-
Verify correct sprocket and chain compatibility.
-
Reassemble the clutch and chain-brake components correctly.
-
Check chain movement and tension before operating the chainsaw.
Always follow the applicable STIHL service instructions when servicing the clutch and sprocket assembly.
Important Compatibility Note
The supplied application information lists this part for the 020 T, MS 200 T, and MS 200.
Because sprocket configurations can vary by model and chain specification, verify the exact model, chain pitch, and parts diagram before purchasing.
