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 Husqvarna 243 take?

The Husqvarna 243 runs a 3/8" Low Profile™ pitch, .050" gauge chain. Available bar lengths: 8", 12", 13", 14", 15", 16", 18", 20". Match the drive-link count to your bar (see the table above).

How do I know which gauge my 243 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 243 are .050", .043" / .050", .050" / .058", .043" / .050" / .058".

Can I put a longer bar on my Husqvarna 243?

Oregon lists 8", 12", 13", 14", 15", 16", 18", 20" bars for the 243. Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
