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.

How do I know which gauge my POULAN PRO/425 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 POULAN PRO/425 are .050", .063".

Oregon lists 16", 18", 20", 24", 28", 30", 32", 36" bars for the POULAN PRO/425. Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
