I have a old Stihl bar with the markings " Stihl 5.80 3003 001 6622 " It's a 20" bar , can anyone tell me if it's a 050 or a 063 gauge bar ?
Not sure, but could the "5.80" be .058? If those are the only numbers on the bar other than part number I'd tend to think this could be the case.

Well, not in there is it.

Nope, I already looked there , but thanks anyway .
The 3003 indicates the bar is the medium Stihl mount which will fit saws from the 024/026 up to the MS660. Yours would have a short replaceable sprocket nose on it which I believe is no longer available.
It is almost for sure a 3/8 x .050 gauge but it could be easily checked by measuring. (I assume the bar info near the base of the bar is no longer legible?) It was probably made in West Germany.

What do I measure , the inside width of the groove ?
Look closely at the area where the bar rails meet the bar nose. If the width of the bar rail groove is the same width as the bar nose groove then the bar is a .063 gauge.
You will definitely see the difference if the bar is .050.
Replaceable bar noses are all .063 gauge.

True with Stihl bars, but not with all other brands.
The tip of my Tsumura bar is .058, and marked .050/.058, as an exemple.

Thank you , I'll try that

I measured the bar groove with feeler gauges and it's .058 . I don't know why Stihl stamped it 5.80 .
Could have been a stamp typo at the factory. ???

....or that is doesn't have anything to do with the gauge of the bar?

3003 Stihl mount bars were never .058 as far as I know. You may have a .050 well worn bar that is worn out to .058.

my question is , are the #'s 5.80 the same stamp and in the same order as the 3003 #'s?
In my travels I've seen saw shops that had a bar reconditioning machine that could regroove a .050 bar to the next size up which is the standard .058
The shop then may have added the hap hazard 5.80

Your not slipping Niko. :D As you can remember we've posted about this exact same topic many times before. This time I left out the "almost all bars". Yes I do remember the old Oregon medium contour bars from 35 years ago that had .050 detachable sprocket noses.And yes my old Jonsered 70E Tsumura bar is .058
But I think its safe to say that todays bars no longer follow that pattern. Just like all the other zillion different chain pitchs and gauges we had in historic times.

The number of pitches surely has been "cleaned up" a lot, but the .058 Tsumura tips are still current production, as far as I know.
Since the bar is a Stihl mount, it is extremely unlikely it is .058 gauge as to my knowledge Stihl doesn't make any bars in that gauge. To measure the width of the slot in the bar, just stick a stack of feeler gauges in there until you get the combo that will go in easily (not forced) and you can move along the slot. This when added up will give you the actual width of the slot/groove in the bar. It will be a number bigger than the bars gauge but will be smaller than the next size. ie, If the bar is .050 which it most likely is, you may come up with a measurement of .056 or something like that but it will definitely less than what a .063 gauge bar which would measure closer to .070"
A new bar's groove wouldn't have wear and would be closer to the chain's gauge.

The number of pitches surely has been "gleaned up" a lot, but the .058 Tsumura tips are still current production, as far as I know.
Thanks for the info Niko, yes they're still available. I own only one Tsumura bar and thats the one on my Jonsered 70E that was given to me this summer.

Yes regarding that bar, but they actually make 13 and 15" .325 bars that are .058. Those are common here.
I remember reading a quick way to gauge your bar using a couple of coins such as a US penny, dime, and or nickle maybe? I dont recall clearly which coins correlate to which gauges though. Anyone familiar with this quick cheat?
Sorry about posting in the old topics, but I might be able to add something to this thread for the sake of the future.
It has been a long time but back in the late 1970s thru the early 1990's my uncle had a Stihl dealership. I worked for him in 1989-1991 while going to college.
As most dealers end up with, we ended up with a bone pile of saws folks didn't want to repair due to cost. We resurrected as many as we could from the piles.
In doing so we talked to Stihl USA on many occasions to source parts, IPLs, Service manuals, and update bulletins.
I have an 030av that wears this same part number bar with a
(https://forestryforum.com/gallery/albums/userpics/57974/IMG_1170.JPG?easyrotate_cache=1579214463)
different number above it next to the Stihl name.
My bar reads Stihl 10.80 then the next line down has 3003 001 6622. same stamp characters.
What I remember is the 10.80 is the date of manufacture being week.year, so 10th week of 1980. or March 3, 1980, to March 9, 1980. I hope someone else can confirm that as it has been a long time.
asfor my bar, it is a .325 x 0.063 (1.6mm)
