How to confirm the fit
- Read your bar. The pitch and gauge are stamped on the guide bar near the saw body — e.g.
3/8" LP .050". - Count drive links. Lay the old chain flat and count the teeth that ride inside the bar groove. This number must match exactly; length in inches is not enough.
- Match all three. Pitch, gauge and drive-link count all have to agree with a row in the table above. Two of three is not a fit.

FAQ
What size chain does a Poulan Micro 25(XX Series and XXV Series) take?
The Poulan Micro 25(XX Series and XXV Series) runs a 3/8" Low Profile™ pitch, .043" / .050" gauge chain. Available bar lengths: 10", 12", 14", 16", 18". Match the drive-link count to your bar (see the table above).
How do I know which gauge my Micro 25(XX Series and XXV Series) chain is?
Check the number stamped on your guide bar near the tail, or measure the drive-link thickness with calipers. Common gauges for the Micro 25(XX Series and XXV Series) are .043" / .050", .050".
Can I put a longer bar on my Poulan Micro 25(XX Series and XXV Series)?
Oregon lists 10", 12", 14", 16", 18" bars for the Micro 25(XX Series and XXV Series). Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
