How to confirm the fit

  1. Read your bar. The pitch and gauge are stamped on the guide bar near the saw body — e.g. 3/8" LP .050".
  2. 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.
  3. 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 take?

The Poulan Micro 25 XX Series runs a 3/8" Low Profile™ pitch, .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 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 are .050", .043" / .050".

Can I put a longer bar on my Poulan Micro 25 XX Series?

Oregon lists 10", 12", 14", 16", 18" bars for the Micro 25 XX Series. Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
