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 4600 take?
The Poulan 4600 runs a .325" pitch, .050" gauge chain. Available bar lengths: 13", 15", 16", 18", 20". Match the drive-link count to your bar (see the table above).
How do I know which gauge my 4600 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 4600 are .050".
Can I put a longer bar on my Poulan 4600?
Oregon lists 13", 15", 16", 18", 20" bars for the 4600. Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
