Default Interchanging saw chains

Assuming the pitch and gauge are identical, what are the limitations on the number of drive links:signs101. For example, if you have a 14 inch bar, 3/8 pitch, .043 gauge, with a 49 drive link chain can you use a chain that has 54 drive links? Is there any general rule for substituting chain with a different numer of drive links. I assume as long as you can adjust the chain to the proper tension, any number of drive lins will work, correct? I have some longer chains that are of the same gauge and pitch, but have varying numbers of drive links.

Thanks

The only problem is the difference in the bar adjuster travel length on different bar styles.

Default Re: Interchanging saw chains

I have 2 saws that are both running 12" bars in .050 L/P chain; one runs 44 drive links, the other runs 45 drive links. The chain off the saw with 44 links just fits the other saw at a squeeze, but it won't work the other way around after the chain stretches a bit, as the chain gets too loose, even at full adjustment.

I also have a saw that runs a 10" bar with .050 L/P and 40 drive links & those chains are not inter changeable with either of the above 2 saws.

I hope that helps?

99% of the time you'll want a chain with the exact number of drive links.

A chain 1 drive link longer may work for a while but as it stretches and the chain tensioner is at max you won't be able to get correct tension on it.... and then you'll have to take a drive link out!

Alright Kevin - I'm in Lymington in the New Forest.

Yes Andover's not so far away at all! I have a friend who has a timber business near Andover so I pop up there time to time Wood by Post

It is to use extra chains that the OP has on hand.
