Questions people ask

What size chain does a Craftsman 79245 take?

The Craftsman 79245 takes 3/8" LP pitch, .043" gauge chain. Drive links by bar length: 8" bar 34, 10" bar 40.

How many drive links is a Craftsman 79245 chain?

It depends on the bar: 34 on a 8" bar, 40 on a 10" 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.
