i,m looking at the ms 250. these r on sale for $300 , stock with 18 bar, dealer said he would change bar to a 16 for me at the cost of new sprocket. ( i have a 20" 036 pro , and a tanaka 12" ) anyones thoughts on a this ( or better ) replacement would b appreciated. 1 reason i,m questioning the 250 is its been available a long time. when will they quit making it ? repair parts seem to dry up after production run stops. this is the reason my 011 (s) r being retired. i havent researched other brands yet. ( the 011 is a 2.5 cubic inch motor and i dont want to go smaller ) thanx in advance
Are they meaning your dealer sure it needs a new sprocket, i put a 16" bar and chain on my cm 211, that came with a 18" bar just was told it used the same spocket and it works great.

when i bought my CM211 i was told it had a 16" bar setup on it, i asked for an 18" bar, and they just put the 18" bar on it and i used it with no problems or signs of uneven wear on sprocket.
When i asked to now put a 16" bar on the CM211, i asked my dealers parts people if i needed to make any changes before using it with the new 16" bar they said none were needed.
So far i have had no problems with the new setup, and have noticed no uneven wear on the sprocket.
The MS250 will happily ron 3/8lp chain but yes, you need to change the sprocket. Eventually repaair parts do dry up for discontinued product but the 250 is so popular you should not have to worry about it for a long time. The 011 was dropped because it did not meet emission standards.

My CM211 does not have adjustable chain oil control, and i at first did not think chain was getting enought oil, spoke to Sthil Support they informed me because of the EPA mandate regarding the oil, so they set it at a very low rate.
After wicking it hard aiming bar at a white paper plate i saw signs of oil.
The CM261 has the adjustable oiler and i can get a lot of oil as needed on the chain.

next problem , do you know of a way to figure drive link count ? ( i,m afraid i,ll over aggravate my dealer if i call him back on that one !!!)
Technical Question for Sthil Customer Support.
I have a Sthil CM261 C-M bought with a 18" Bar and Chain, i also bought a sthil CM 211 with a 18" Bar and Chain. I now want to put a 16" Bar and Chain on my Sthil CM 211 will i have to change sprockets?
===========
This should answer the question as to the need to change sprokets on your Sthil Chain Saw.

Sthil's Customer Support Answer.
We are in receipt of and thank you for your email.( No you will not have to change the sprocket, just the bar and chain.)
Thank you again for contacting STIHL.
??? The MS211 is equipped with 61PM chain, 3/8 lo pro. The MS250 comes with .325 unless otherwise specified so the sprocket definitely needs to be changed.

Happy saw guy. You can either take some unknown person(male or female) response and possibly ruin both a sprocket and chain or you can take the info from professionals like sawguy and at least lay the two saw chains side by side, if one is .325 and the other is 3/8 the difference is noticeable.

The reply came from the Sthil customer support, are you implying their people are unknown?
I just did not include the persons name in my post, anyone can also contact Sthil support by going to their contact site on their web site.
Also i am in no way trying to demean anyone on this forum, i am just posting what i was informed by Sthil.
I installed a Sthil 16" bar& Sthil 16" chain, on my Sthil CM211, that had a Sthil 18" Bar& Sthil 18" chain when bought new and it is running smoothly with no problems.
I am just guessing .05 difference does did not require Sthil to make a diffrent sprocket.
there may confusion in what you are doing. are you wanting to change the pitch of the chain, i.e. from 3/8th lp to 0.325? then I think you will. the way the question was asked, it could be interpreted that the pitch is not changing. I think I would go to you dealer with the saw, and what ever else you already have, and lay it on the counter, and have them show you what and why. I have a sharpening chart with all the specs for the different pitch and gage chain. the sprocket may have different spacing, and also be a different style.
do you have bulk chain, or loops used? what do you use the saw for. do you mean 3/8 lp or standard 3/8ths.
@Happysawer (https://forestryforum.com/board/index.php?action=profile;u=52555), to clarify this for you, you asked if the sprocket needed changed because of a change in bar length and they correctly said no. The original poster @CUT N RUN (https://forestryforum.com/board/index.php?action=profile;u=53087), asked about changing the sprocket because of changing the bar length and pitch, he needs to change the sprocket because of the change in pitch from .325 to .375 (3/8) not the bar length.
As I'm sure quite a few on the chainsaw "hangout" section know, the same (according to Oregon) link count on a 100' roll of 3/8lp as well as 3/8 std. 1640 if I remember correctly.
@CUT N RUN (https://forestryforum.com/board/index.php?action=profile;u=53087) , if you can give the driver count # of what your current chain is, then you CAN come up with the number of drivers on whatever (ANY size) chain you want. The saw might not pull it effectively, built can be done. For a ridiculous example, (to express my point) .325 to .404, with minor extrapolation 84 link of .325 is 4.54'. 67 link of .404 is 4.53'.
BTW, I'm coming up with my numbers out of the 2018 Oregon Master Catalog.

and yes , for all concerned , i am changing pitch , if i get the 250, from 325 -to 3/8--- 63pm...( the reason again is i have a whole bunch of these sized chains )

If you look at both the sprockets on the CM211 and CM261 you will see why Sthil is saying you won't need a new sprocket.
T
he CN211 has the chain being driven on the outside by external tooth sprocket.
The CM261 has the chain being driven on the inside of the sprocket.
Both chainsaws have completely different type sprockets, you can use the same chains on each, because of one being external and the other internal.
You would have to see them to really understand just what i am trying to explain, but where the chains drive teeth interface with both sprockets they are the same spacing.
This is the reason Sthil said you don't need replacing the CM211 sprocket.

3/8 picco - i have several brand new stihl loops , probly 20ish 3/4 life left or better , and at least 10 others.
i,m cutting downed trees , standing dead trees , trimming others. here in ohio its been a race to cut the ash because of the bug thing. most cutting is done on a 35 acre farm i help manage , that is about 1/2 woods. i,m feeding 3 woodburners., and sell a bit, if i can. oh , and the gf likes her jd n coke sitting next to a good camp type fire !
so the pitch is the same, does the 3/8 p kick out the wood for you. I have that on my pole saw, and it has small cutters.

it can kick a bit if you go at smaller branches to low of a rpm. I own a foley bench grinder , and when i was learning to sharpen , i cut the depth gauges way way too low on a few chains . those were dangerous , but , cut real quick with the saw wound up....
C N R, bear with me, I'm going to answer @docs question 1st.
No, it doesn't, reason being: Power! I've HEARD of a 3/8lp chain with skip tooth, but upon close examination, it is regular 3/8 skip. It shouldn't, but this saw shouldn't have either! According to the information that I've dug up so far, in normal crosscut fashion.325 will not hold up. This is what is being said to me at my local saw shop. Oregon says other. They have a definite lack of interest in the situation, so...
C N R, 63PM = 91VXL = Round ground semi chisel fullcomp chain, BTW Buckin Billy Ray is wrong in his say that full comp IS full house. Full house has 0=ZERO empty space between cutters. Full comp is normal. 3/8 55DL is 3.36', .325 55DL is 2.97'.
doc, BTW, Oregon term is 3/8lp, Stihl is Pico. Same thing but different name, but be careful on assuming, I KNOW (for example) .325 RS Stihl has ZERO green chain features whereas Oregon, even if they say it's yellow chain, just SCREAMS green!
so @Happy Sawyer (https://forestryforum.com/board/index.php?action=profile;u=24802) you are saying he can go from a 0.325 sprocket and chain, to a 3/8th p chain using the old sprocket? if I am hearing him correctly. I only know my own stuff, not claiming to be an x-pert. :)
C N R, I hope I've answered your questions, but in re-reading the question, I have certain doubts as to the question. Please tell me if answered completely and sufficiently. My mind is just TO scatter brained, always, that's why I have books! I've just not had pen/pencil and paper handy since working in my career. Long story 😱
doc, NO, you cannot do it (unless you like damage and/or short life span to components)! lp or pico, reg 3/8 , yes! .325 to ANYTHING else- NO. 3/8 isn't quite .375", more like .366". Nothing on 1/4, .325, 3/8 anything or .404. Those 4/5 (depends on how you look at it) ARE DIFFERENT!
that is why I asked, as I am still not sure what the OP "intends" to try to do. I agree with your comment and why I keep trying to clarify! thanks all.

I might add if i return the Sthil 18" bar and chain to the CM211, the chain will again run on the external tooth drive of sprocket, where while on CM261 it ran on the internal part of sprocket.
Happy Sawyer, I still don't think that you've answered doc's question (or mine) to his satisfaction. I know what he's asking. I'm just not sure exactly HOW you're trying to say it to his satisfaction, or mine.

Doc. the two pictures you posted one of your 261 the other your 250, they show the just what i am trying to describe, on the 261 the chain is being driven on the internal part of sprocket and on the 250 the chain is being driven on the external part of sprocket.
@doc henderson (https://forestryforum.com/board/index.php?action=profile;u=41041) , your turn to try. Because I still don't know what message he's trying to convey. As far as relating to the DL question. I may be the one not understanding though.
I agree with that. so the question, can you run 2 different pitch chains on the same sprocket? (not at the same time of course). honestly the question. put a 3/8th pitch chain on a 0.325 sprocket?

If you look at the pictures there two diffrent sprockets, but one is just an external tooth drive the other has a internal drive sprocket.
It's just the CM211 is using a design of only the external type, the CM261 has a different Design sprocket.
This allows you to run the same chain on both the CM211 and the CM261.
thanks for the reply @Happy Sawyer (https://forestryforum.com/board/index.php?action=profile;u=24802) , and I do not mean to put you on the spot, but I understand him to be saying that he wants to use his 3/8th p chain on a 250 with the original sprocket. @CUT N RUN (https://forestryforum.com/board/index.php?action=profile;u=53087) please correct me if I am wrong. thanks guys!

It looks like the 250 has the same external tooth drive sprocket as is on my CM211, so i am guessing he can put the chain on and it will work, he should know by looking if the chains drive teeth are they fitting on the sprocket right.
What does it matter if the chain is driven from the inside or the outside??,, Just so long as the chain ,sprocket and bar tip are the same pitch, either .325 or 3/8 Steve
Roger that. Correct size for the drive links is what matters.
That's a good illustration of one of the differences between the pro saws and the others. Pro saws the sprocket is a separate item and replaceable. HO and Farm saws, the sprocket is fixed to the clutch and you have to replace the clutch to replace the sprocket.
Not sure how long it's been like that.

And these chains are 3/8 lp or picco , or 91..

the 250 comes stock with irrelevant 18" bar , geared for .325 chain. MY dealer said the sprocket needed changed out because of the differing pitches of the chains , regardless of bar length . i,m ok with that. one sprocket cost is i,m sure waaaaay cheaper than buying several new chains.... now the d. l. count...my chains are 55 . what would the count b on the 250 ? pics of the saws , bar and chain
C N R, what pitch chain are you wanting to run? What brand bar?
If Oregon brand bar, I can help. If Stihl, I can only make an educated guess.
What pitch is the bar TIP set up for?

What pitch is the bar TIP set up for?
pics and description of chain r above , . and if i get the 250 , it will b new from a stihl dealer , i,m assuming they will install a stihl bar. bar tip pitch ? i am clueless !
so if you want to put the bar and chains in the picture, on the 250, take them to the dealer and have him get the saw out of the box, or better yet the service guy, and see if it will work. make sure the bar will bolt up, and an appropriate sprocket can go on your saw. my dealer will usually swap a few things out for free, if it is not too big an upgrade. I do not know, but I think and 0.325 chain may make bigger chips, so if it were me, I might keep the original sprocket, bar and chain and compare. you then can get a new 3/8th sprocket, to use up you old bar and chain collection. you may decide the original stuff mated up with the saw is better and eventually return to it. especially if the dealer charges you for everything new anyway. thanks all for helping to solve the mystery. :) :) :)
the sprocket, and bar tip and chain all need to be the same pitch. the gage of the drivers need to be the same as the bar grove. you are correct. the dealer can help you with mating up the old stuff if possible to the new saw, or leave it original, and sell the old bars and chains on EBAY or such.
it may turn out that the way the bar adjustment and sprocket are configured, that you would have to add a link, and the dealer may want to charge you for that. that is why I would take it in with you. good luck.

so if you want to put the bar and chains in the picture, on the 250, take them to the dealer and have him get the saw out of the box, or better yet the service guy, and see if it will work. make sure the bar will bolt up, and an appropriate sprocket can go on your saw. my dealer will usually swap a few things out for free, if it is not too big an upgrade.

dealer said he has the 16" bar to run my chains , and would do the swap at the cost of the sprocket. if the bar happens to be the same as mine , so b it , i have some beaters left over. the 325 may be faster , i,m not really concerned on that front . saving $$ ( using up my existing chains ) is my first concern. ( and when i,m cutting for others , i generally get paid by the hour !!!! ) thanx for all your help

when the time comes , i dfinately am taking a chain or 2 with me . many of my chains have come from others , used , and i,ve shortened many and spliced a few to make them fit . taking out a link is 1 thing , having to add 1 would really suk .!! but as murphys / my law goes i,m sure they will have to be longer. i have checked into a echo of comparable engine size as the 011 . and with the same chains / bar length , they r 3 links longer .
I think the confusion lies in the type of sprocket we are looking at. The ones on your 011 and the MS211 are spur type where the drive teeth are one piece with the drum, if the chain pitch is changed the drum needs to be replaced. If on the other hand the saw has a floating rim only it needs to be changed, this is more popular on the larger pro units that are seeing heavy use. Ineexpensive and quick to replace. Either way 3/8 picco (lo pro) and .325 are not interchangeable on the same driver

heres a video of diff. between 325 - 3/8 cutting . i didnt notice much diff. in cutting . -but he also shows 1 version of sprocket diff. and ( as a bonus ) you may , as i was ,, be super impressed with his safety sandals !!!!!

hard to know if the sharpening skill on the 3/8 makes it equal to a new 0.325. neat video. lower rakesr makes it more aggressive, and pulls into the wood to a point, but if you hold back due to the feel then it may slow you down. I know my 3/8 throws bigger chips. need to match the chain to the saw. RM is safety chain and they claim it cuts just as fast and stays sharp longer. the RS is the more aggressive chain, non safety. i like the way it cuts and it seems faster to me. find what you like and make some firewood!
