answered mostly by experts. I apologize to "Fred" and Rick, because I saw where you guys posted on this thread, but atleast neither of you were the ones passing yourselves off as the authority.

For the rest of you guys, swing by the Tool Shed and check out the thread titled "chainsaw chain pitch question". The self appointed experts have nailed down every answer but the right ones, LOL.

Well since I`m the buffoon who found this gem, I have taken literary license to edit out most of the more lucid and informed replies and have thus condensed the remainder of the thread down to the parts that I found funniest or most misguided. I`d like to reply to the thread, but alas, I have been banned since I have nothing of value to offer over there.

Here it is, enjoy!

chainsaw chain pitch question?
Posted by runlong (My Page) on Mon, Jan 19, 04 at 10:20


I am looking at purchasing a second "larger" saw. The saw I am considering comes with a 24" bar

(used). The chain pitch/gauge is .375/.050. I would be looking to get a smaller bar for this saw.

The manufacturer lists different bar/chains with pitches of 3/8, .325, and .375. Some of the .325

and .375 bars are listed for the saw I might purchase. Since the saw already has a .375 bar/chain

I would assume that I would need to stick with that pitch or else change the sprocket. My

question is, what is the difference between a 3/8 pitch chain and a .375 pitch chain since 3/8

=.375?

i think metric measurements is the only difference.The .375 sounds more metric than 3/8.Keep in

mind to that your chain pitch will have to match the bar pitch,if your usin a sprocket nose bar.

Your choice is limited by the power of your saw.
.375 is just 3/8 lo-profile chain and is used on saws with less than 2.5 cu. in.
To be able to use .325 chain, you need a motor with at least 2.5 cu. in.
You will find that the drive sprockets available from either OREGON or the saws Mfgr will also

limit your choice.

3/8 chain is the same as .375
3/8 low-profile chain is .370

My saw is running a 3/8" low-profile chain. My oregon manual says nothing about an actual .370

pitch for a 3/8" LP chain. I'm confused by this. Is a 3/8-LP chain compatible/interchangeable

with other, not lo-profile, 3/8" chain?

I'm confused. Isn't the pitch simply the distance between every third rivet?? If so, 3/8LP would

definitely fit on any .375" saw, since .375 is 3/8" anywhere you go. I've not seen any

specification anywhere referring to 0.370", though I should state that I'm a novice compared with

most on this forum.

Bob
You are confused because you are being misinformed.
Here in the US we use both Fractional and Decimal system.
Decimal .375 is equal to the fractional number 3/8".
Just take 1 divide it by 8 then multiply that number by 3 and you will see that .375" is equal to

3/8" just as Yourself and Runlong already knew.

This number has no bearing to "Low profile" chains nor anything else other than the pitch of the

drive sprocket.

Look at the pic below.



Chain pitch is determined by measuring the distance between the top of the chains guides and

dividing that number by 2. Pointed out here as A. If you were to take a .375, 3/8 chain and shave

.005 off of the distance between the guides. That will not give you a low profile chain.

What a chain "is" all has to do with the Drags in relation to the cutting teeth as pointed out

here as B . The combo used here will determine if the chain is a Low Profile, Chipper, Low

Kickback, Ripper or a Billy Mayse Orange peeler Special..

sooooo........ will a 3/8" (.375) pitch chain work on a bar/sprocket currently set-up to run a

3/8" LOW PROFILE chain?
Now I'm even more confused as my Oregon manual tells me:
"chain pitch is the distance between any three consecutive rivits, divided by two." To me this

means "B" in Les's picture. "A", the distance between the drive links, is not even mentioned in

my manual. However, just eyeballing the two, they look to be almost identical.

well i aint gonna say sure .. but i do know low pro dont fit standardard 3/8 sometimes . not rite

any way.. course i could always be wrong. but its never happened before..

Posted by: hokiebob1 va (My Page) on Tue, Jan 20, 04 at 16:50

Thanks, but I thought thats what I said-a 3/8's chain is the same as a .375" chain, which is the

distance between every third rivet (I forgot to divide it by two). This designation only has to

do with the drive side if you will, of the chain, not the cutting side. Is this right?



--------------------------------------------------------------------------------

RE: chainsaw chain pitch question?

All of the below chains are 3/8" and made by Oregon.
If you notice. The design of the cutting teeth and drags along with their height are differant

and that is what makes a chain what it is. The pitch number has no bearing on what type of chain

you are using.

Low Profile


Micro Lite


Ripper

Sorethumbs
If you look. The distance between any three consecutive rivits is the same as it would be if you

were to measure the distance between the top of the guides.

Fred
You say, "I do know low pro dont fit standardard 3/8" sometimes". Yes it will. BUT, The saw

manufactor may call for you to use a Low Profile chain. This is mainly due to the cutting teeth

sticking above the bar so far due to the thickness of the plate that they may hit and damage

something on the saw.

Maybe I'm wrong. Enlighten me.
If not low-profile, what is the ".370" chain that many online dealers sell?

If the drive links are the same length why do you need a different drive sprocket for low profile

chain if it really is .375? I've read in the yahoo milling group that running 3/8" low profile on

a standard 3/8" drive sprocket will greatly increase your chances of breaking the chain. Stihl

must sell separate low-profile drive sprockets for a reason. No?

Posted by: ricksvar 6 (My Page) on Wed, Jan 21, 04 at 7:21

Well I'am probably wrong,but a 3/8 sprocket for low profile chain like Stihl PM and a 3/8

sprocket for say Stihl RS chain are going to be different.While spacing is the same,chain

guides(drivers)are smaller on the low profile and larger on RS.Note the image above.Also if you

have a bar with roller tip it should match the pitch and size of the drivers.RRRRRrrrrrr,does

this make sence?

And I have always thought the plumbing industry was the most screwed up industry on earth. Now

I'm beginning to re-consider.

That was good for a laugh,Russ. So does the .375=metric guy qualify as "scary-stupid"?:D


"Just take 1 divide it by 8 then multiply that number by 3 and you will see that .375" is equal to "

Or if you are in to higher math divide 8 into 3?
:rolleyes:

I saw that and thought for a minuet about chimming in, but then thought better of it!

WOW is all I have to say.

Who said that dealer support didn't matter?
 
chain

I thought of answering that thread, but i figured they wouldn't know the right answer if it cut them on their knee.
Does this come under the heading "Ignorance is bliss?"
 
I haven't seen anyone over there who I deemed worthy of a reply.

So am I going to get some help over in the off topic forum here if I ask questions about wheelbarrows, tillers, cordless drills, etc.?

Oh yeah....and wateringcans. Fish can answer those. ;)
 
thanks russ ,, i thot the guy sounded so sure ,,but didnt jive with any info i had...
i think i bought a sprocket from this guys sister yesterday . thev owners wife was sure that was the closest fit ,,i could get..
i know ole fred over there and i be nice about it .. but im gonna just plain tellum ive had it confirmed that he is giving wrong info and thats enuff said.. everybody use your on judgement..wish u would talk to him tech and mabe wise him up.. hes got a right to know hes just wrong..whether he chooses to cuss me out is never mind to me.. he aint getting no cherry in that regard.. thanks for this post russ.
 
Hey now, that is my turf you guys are dissin'.
I am still an untouchable over there. I should have been
banned there a dozen times, but I am teflon coated there.
I always like a nice wateringcan., but the off topic forum here
I rarely visit, but I think I will change that policy, as there are
many arborists here I have yet to offend.
This forum here is a divided one.
The earthy element here prefers to bring the tree down to deal
with it, while the other faction prefers to flit around the tree-
tops first, kind of a Peter Pan syndrome.
A real man would drop that plant, land where it may,
then chop it up accordingly. Houses or powerlines???!!!
Only pussies worry about issues like that!!!!!
I hate to be the one to define the differences of the members
here, but it is my job. The men know who they are, as well
as the pussies.
Nothing personal of course, I used to date an arborist.
He made a curry sauce that was out of this world!!!
 
No offense taken, Brian. Just giving you a hard time. If you really want to offend me...tell me I'm a poor housekeeper. You'll be right, but I'll still be offended. :D
 
Hi Tony,

I only included Fred`s post to show that some people weren`t buying that nonsense. Fred is a pretty straight up guy and I`ve got nothing but good things to say about him.

I could go back and register under a different name, the way tjf does here, but in just the same way that we all know it`s Tommy, somebody over there is bound to recognize me. Since Spike`s alter ego Fish is my friend :heart:, I don`t want to make too many waves. Fish Spike already has too much internal conflict.

Russ

Checking out some of the other sites can be really entertaining. Once in a while I get the feeling I'm not the only id!%t in the country.
 
thats a talented lady.. note the coordination an all. hmm. by the way its 3am here so i could give it a good look..
yall be sure get this buried fore libby gets up:) :)
 
Fish wont let me drink his hooch,says I'am not special so can't have any.He says I'am a "failure to communicate."

3/8 LP

Rocky

you are wrong about all this being unneccessary for me.I did not know that the 370 drive links were lower than other 3/8 chains. I have read many books on chains and othe information about saws I may have read this but do not remember it.

I am a member of the Garden group and read the thread. There was a lot of misinformation.

Fish and Butch will give answer to question asked on the Graden thread some times. they are good with their help.There is no question about the answers they give. you can bet it is correct.

The one's asking for help on the Garden threads need answer that are correct. The members of this site should step in and help the person asking.All members on this SITE are ready to help when asked That is the nature of each one of you.

Rocky if you could go more in dept on the different pitch and gauge on bars and chains it would be a help to me. I get confused with bar and chain pitch at times. example 3/8 with 58 gauge 3/8 with 50 gauge then there is the 1/4 pitch. will a husky 20" bar with 3/8 pitch 50 gauge work on my stihl MS360.

I thing I am a self-respecting sawer NOW I am not sure

Thanks to all of you for caring for other and giving help when it asked for.
