Drawing: pitch is the distance between three rivets divided by two — **Pitch** Measure across three rivets and divide by two. Common pitches are 1/4", .325", 3/8" and .404".

Questions people ask

What size chain does a Husqvarna 345E take?

How many drive links is a Husqvarna 345E chain?

It depends on the bar: 66 on a 16" bar, 66 on a 16" bar, 72 on a 18" bar, 72 on a 18" bar, 78 on a 20" bar, 78 on a 20" bar, 80 on a 20" bar. The bar length is usually printed near the mount.

Can I use a chain with the same length but different pitch?

No. Pitch and gauge have to match the bar and sprocket, and the drive link count has to match the bar. A chain that is off on any of the three will not fit or run safely.
