Chain cutting teeth

[RobW]

New to chainsaws

Can anybody advise me about the number of cutting teeth on chains.

My original chain was Oregon 3/8inch/1.3mm/55links and had an even number of cutting teeth but my replacement chain Stihl has an odd number of cutting teeth which results in having two consecutive teeth on the same side of chain.

Is this normal?

Any help would be welcome

Yep . Can be normal . I used to use the 2 same teeth as the start / finish marker for sharpening ( on a 200T )

Yes this is normal. No need to worry about it. In fact that is where I start sharpening from if I don't have a marker with me.

also if it's 3/8 chain it'll be more like 1.6 gauge not 1.3

Unless its 3/8 lo pro ......

Talking about the common "full comp" chain (as opposed to skip chain - different and more distorted story), the sequence will always be distorted in some way on chains with odd dl counts. Exactly how it is distorted some times depends on the choise the one (or factory) that makes the loop in question made.

 

Only chain with a dl count that is devidable with 4 will have a totally uniform sequence all the way around.

Chain with a dl count devidable with 2 (but not with 4 - 66dl is a common exemple) will have 2 cutters in sequence on the same side at one point, but otherwise be undistorted (= same distance beween all cutters).

 

None of this really matters, unless the loop maker messed it up in some way.

Regular 3/8" chain in .050 (1.3mm) is very common in large parts of the US.

 

It doesn't make much sense, but it just is that way.....

With a 55dl chain there basically are two choises:

 

1) Keep as many cutters as a 56dl chain (14 on each side), but delete one dl and one tie strap at one point. This will result in an even number of dl, but the distance will be short between two of them.

 

2) Delete a dl and a cutter instead. This will leave you with 14 cutters one one side and 13 on the other = two in a row on the same side, with a longer than "normal" distance beween those two.

Yep I once bought a 385 from U.S.A. with a 30" GB bar and it was running .050 3/8 semi chiz .

Yes, something to watch out for when buying from the US.

Wow guys! Thanks to all who replied. Given me much to think about.

The chain gauge is definitely 1.3mm and SawTrolls 2nd explanation is definitely the what I have got, also from what I can see most small chainsaws seem to be 1.3mm gauge.
