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 266 take?

The Husqvarna 266 runs a 3/8" pitch, .058" gauge chain. Available bar lengths: 13", 15", 16", 17", 18", 20", 22", 24", 26", 28", 30", 32", 34", 36", 42". Match the drive-link count to your bar (see the table above).

How do I know which gauge my 266 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 266 are .058", .050" / .058", .050" / .058" / .063", .050" / .063", .063".

Can I put a longer bar on my Husqvarna 266?

Oregon lists 13", 15", 16", 17", 18", 20", 22", 24", 26", 28", 30", 32", 34", 36", 42" bars for the 266. Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
