- Fitting a 30 Inch Longer Chainsaw Bar to my Stihl MS 391. The MS 391 has the 20 Inch Bar standard and 3.3 KW of power.
Will it run the Longer Bar? How will it Cut? Will it be effective? The Stihl Farm Boss MS 391 is a Medium Sized Chainsaw and was perfect for my Previous Property where the trees were all a smaller size. My new property has some much Larger Eucalyptus Long Leaf Peppermint Trees that I am cutting up for Firewood this Winter.
I Cut some large diameter Rounds of firewood with the Longer 30 Inch Bar with Full Chisel Skip Tooth 3/8 Chain, Split them with my Fiskars X27 and bing the firewood back to my house with the Land Rover Series 2a.
I find out if you can fit the longer bar to your chainsaw.

I would turn the oiler adjustment up to compensate for the longer bar, if it has that option.
Cool video. I'm glad the longer bar is working out. 😎👍
I ran a H 362 for 15 yrs. Been çutting for 50 + yrs. Just this yr - bought a 572 with a36 inch bar. It is a pro saw. Best I have ever owned. Wish you well.
Very cool. Helped me, along with a couple other videos, decide to put a longer bar on my Husq Rancher 460. Testing it out today. Cheers.
Awesome! How did it go? Were you happy with it?
What size bar did you go. Any info on bar brand and details. I wanna go bigger than 24#
@@ryanwolf1938 I am putting a 28” bar on my Husqvarna 460. Will be making a video shortly
Looks like a charm and time saver... those are some huge logs and beautiful landscaping
Fire wood paradise 🪵🌄😄
Interesting video stihl sells the ms 391 with a 25 inch bar but the max recommended bar size for the ms391 is actually a 20 inch bar look forward to your review of how well it does with a 30 inch bar or even a 32 inch bar
Lovely surroundings... 👍
Will a 311 chainsaw run a 25 inch bar
I used to run big bars . Now I’ve gone back to 20 inch . You can cut 50 inch tree with a 20. Bucking is a bit different of course. Less chain ,less cost.less time filling. Easier on the saw . Keep your chain sharp and not to aggressive on the rakers it’ll be ok mate.
Long bars are unnecessary here where I live as average tree diameter is smaller than 12". With bore cut method 13" bar is enough for 28" trees IF you know how to do it. It's not dick measuring contest, guys
I understand wanting to use a longer bar so you dont have to reach over top of the tree at an uncomfortable angle or going around to the other side. I run a 28" bar on my 70cc saw,a 20" on my 59cc saw,and keep a ms250 for limbing and smaller trees. The biggest stuff I usually cut is 32" oak and my ms441c handles it with ease and comfort.
Looks like she handles the bar just fine plenty of power wow
That saw can pull it if you've got a sharp skip chain and don't dog in too hard but I'd seriously watch that oiler, I don't think it will keep up with that much bar deep in the cut. Also you'll want to keep a 7 pin sprocket if you go bigger you'll lose even more torque which you'll need with that longer bar
I thought the chain brake was on at first but once you got it spinning and I seen and could hear it’s way tight. You want it tight but not too tight. Try only tightening it till the chain touches the bottom of the bar. It is really hard on the crankshaft bar and everything in between. Very good video though. Not many people show and explain going over manufacturers recommendations on bar length.
nice video though! glad you're pleased with it, full skip is a good idea too
Try turning up the oiler. It's a screw at the bottom of the chainsaw. I had to turn up mine when I fitted a longer bar on it.
Saying the paint was the problem but sounded like to me that the chain was too tight even after it said the paint cleared it still sounded to tight, that bar want last long with the chain to tight, it will spread the bar out at the end
it was too tight, heard it too.
Yup
It did well on that length... and it probably oiled well too.
If you where local I'd donate a old style husqvarna combi can. They are brilliant. Makes refills super fast, spill free and is an excellent place to keep your scrench/file. Holds plenty to run a 90cc all day unless you are milling of course.
Grab PPE, saw, can and go.
I have a 25 on my 391 and it does just fine. A bit unwieldy, but it works.
very good work, friends, be careful, nice to meet you from me.
Good info. Nice Land Rover.
good work. your helping more than you reliise
Awesome video
Any update on how well this bar extension held up over time in terms of wear and tear on the engine?
Nice truck!!
Awesome
I’d say have a look for a greasing point on the other side of your bar tip..! It could be greasable..! Maybe that’s why was sticking...
Very nice, I have a Stihl 039 that I want to run a 24" bar on. Your video gave me the info I needed, thank you.
Thanks Gary!
I have a Stihl 029 and I run a 24 inch bar on it
@@devanmangas3474 did it bolt right up?
File the chain at 25 degrees face angle and the file flat and level . Leave her with a 3/8 7 rim. These saws can handle a 32 if used with a gentle hand. Smart to save the back.
3.2kw? sounds like an electric heater 😂
Nice landy mate
chains abit tight]
Great vid mate -:30 is big 😃 is that just Cheap engine oil as bar oil mate ? I've been thinking of doing that tbh
You need to let you’re saw warm up otherwise you could really damage it
I think the beauty of video editing software is that there is so much that the viewer does not know ... and never will.
Joseph Dignam okay😂I’m sure you do but I know so many people that don’t and then they’re left wondering why it doesn’t work anymore
Tom Hints Let the ignorant and stupid do as they think right. Then the rest of the population who they don’t know everything about anything and are open minded and not afraid to learn can reap the rewards :)
But must point out, even the OEM procedure for “warm up” is quite brief... there is no way the piston and cylinder barrel temperature relationship is where it wants to be after revving it up a few times :)
Joseph Dignam I completely agree with you👍
Thanks i didn't know a chainsaw runs like a classic chevy pickup. That's good to know for longevity.
hows the bar now going after a couple of years?
"Longer" as in the brand or the longer bar? or both?
anywho, nice video^^
Both I would say:)
Thank You.
I'm tempted to put a longer bar on my Farm Boss for when I resaw logs.
It’s going well I’m getting used to it now, it’s a pretty handy thing to have as an option. I have cut a lot of firewood with it since I made the video a month or to ago and I’m still happy the quality seems ok so far.
I have a farm boss too have you done it yet?
Ah the saw that wishes it was a 362. I run a 36 on my 460 and a 28 on my 362. But I have my eye on a 880 :).
Haha yep you r right, how good would an 880 be:)
@@offtrackprojectsandmainten5681 How good you ask.......the stuff dreams are made of! It will damn near make you breakfast and start your car when its cold out.
What a gorgeous area! Is this your land?
idk why the forest service doesn't sell wood permits to old burnt areas, the last permit I got was for this big area but there wasn't jack shit and when we dropped a few trees they said we couldn't, like what's the point of buying the dang thing, if there isn't shit to cut, there's this massive 20,000 acre burnt area about 13 miles away from me, they don't sell permit for that area so I just cut in the national forest lol.. I'm done buying wood permits to an area with nothing to cut.. nice saw though and I have a 21'' bar on my saw..
Great video

You’ll end up burning that bar. That saw doesn’t oil enough to lubricants it properly. You will also burn that plastic saw up. Not made to pull long bars like that. 462 minimum for a bar that long.
I agree.
Can you open up the oiler on the 391 to get enough oil? I am considering doing something similar.
@@robertgeer7711 absolutely not. Not a 30in bar hell no. Do not run to at length bar am that plastic clamshell saw. It’s not made to pull it and you’ll end up burning it up. Get a 462 if you need that much bar. Anyone who needs a bar that length on a homeowners saw is asking for trouble. But to each their own I suppose.
@@stephanmackie5281 Thank you. That's why I was asking.
@@robertgeer7711 no worries brother. Yessir. 70+cc saw class is minimum for a bar that long.

what muffler did you end up finding that fit? I was reading you had to replace it
Saws can only support certain lengths of bars.. u should be able to run a 36" bar on that saw easy..
The oiler output on a farm and ranch saw would be inadequate for a 36" bar. Also the farm and ranch saws are a clamshell design and only one bar stud is actually threaded into metal. The other screws into the plastic housing.
@@ciphercode2298 saws only have limits... I bought my ms311 brand new years ago . And it still runs fine.. I run a 24" to 28" bar.. I can put a 32" on it but why when I got 372 xp
@@Hollywoodhouse74 I'd run a bar like that in a pinch if I needed to,but its use would be limited. I can run a 24" on my ms310 and you've gotta take your time if you're all the way buried in wood. Like you I keep a 70cc saw for bigger stuff( ms441c) I keep a 28" bar on it and it's much more practical for 24" and up firewood. Like I said,the bar mounting stud and capability of the oiler would limit what should be run. Certainly a 3y" bar would be ridiculous to run on a 59cc farm and ranch saw. If you need to cut that big of wood,put up the money to buy a saw that can handle it or farm out the work to someone who can help you with bigger saws.
@@ciphercode2298 any time u wanna go cut I'll out cut u .. I can cut a cord of wood from standing trees.. loaded in my truck and stacked.. in 2 hrs.. so wtfe.. a ms 310 is smaller then a ms 311.. and short bars are dumb
@@Hollywoodhouse74 an ms310 and 311 are the same saw genius. Look,I'm not tryin to get in a whizzing contest with you. You wanna cut wood with an ms880 or a ms180 that's up to you friend. God bless you and have a great day.🙏
is that a good quality bar and chain?
How wide is that wood?
i hqve the same saw with a 28" bar. does this tend to bog down and not have enough power for you with that fullskip chain?
Hi As long as I keep the rakers adjusted not to aggressively it’s fine. I think you need the skip tooth though otherwise I think it may struggle for power. The other option would be to change the drive sprocket to down gear it. I was thinking I may have to do this but for the timber I want to cut with it I think it’s fine. Just enough power to cut a log the full length of the bar at a reasonable pace.
Don't waste your time or your back. Running a longer bar decreases the rpm's. I own many stihl products, and I tried putting on a longer bar, but it will run slower which means it will cut slower.
I have a 14in stihl chainsaw can I extend to 18 and still run good
@@silvestremanz5166 , if you are going to use up most of the 18" bar in a log, then the answer is no.
Thanks for this explanation.
I was thinking of putting a longer bar on my saw. I figured it would dog out the engine a bit but it didnt occur to me it would spin the chain slower as well. Having watched him cut that 28" log I was unimpressed.
Took way too long to really be worth the modification, especially since he cut them all in half again anyway.
Full comp chain... ur gonna love filing it...
I think stihl is under rating this chainsaw saying max 20 inch bar odd how I saw it in stores with a 25 inch bar
I found the oil output to be the problem. Drilled out the oil ports on the bar, works like a dream.
@@TheWoodsmanMilling very Interesting nice information
@@AntonioClaudioMichael power wise, anything from the 261 up can probably take 4-6 inches longer of a bar and chain. Use to, the 391's max length was the 25 inch.
Edit: that said, longevity is questionable if you do that.
@@TheWoodsmanMilling very nice information you rock
@@AntonioClaudioMichael I run the 661c-m, and I've ran the 36 on it a couple times now. It's got more than enough power for that, so I'm looking at getting a 42.
Chain is to tight
Maybe do some research on the arborist/chainsaw forums before buying a junk bar, putting the wrong chain on it for Aus hardwoods, and putting it on the net for other beginners to see. Sorry, my 2 cents.
What size saw is that
It’s a sthil Ms391 Farm Boss. 64.1cc 3.3kw
th-cam.com/video/amehsa_t_o4/w-d-xo.html
👍 . You didn't have to change the sprocket? Been wanting to do this on my ms311 but thought I would've had to change the sprocket.
I have a 311 too, did you try the larger bar yet?
@@yoesomite2199 not yet. My brother borrowed it and I just got it back but now it won't stay running longer than a minute. Now I'm waiting on a new carburetor to come in. But I do have a longer bar and chain to put on it when it gets going again.
A ms311 will run a 24" bar ok,but if you're cutting hardwood you may not be able to lean on it to much. No need to change the sprocket as long as it's already 3/8 and 7 tooth. It's written on the clutch drum. On a stihl with a 24" bar youd need a 24" chain,3/8 pitch,and your chain gauge and bars gauge must match. It also needs to be 84 drive links,if memory serves. The bar information is stamped into it near mounting holes.
You will wear out your engine sooner than expected!
What I know is you divide the number of cc by 3 the answer will give you the maximum guide bar length taken by the chainsaw
Skip chains are for ripping NOT cross cutting. I run a pair of 660 magnums milling with 42", 60" and 87" bars the 87 is a dual power head bar using full skip ripping chain. Cross cutting with a ripping chain is dangerous.
Skip chains are not for milling. You can certainly mill with them,but the only thing that differs from crosscut chains to milling chains is the angles that they are sharpened. Milling chains are sharpened at 10 degrees and crosscut chains around 30 degrees. Skip tooth chains were invented for use on longer bars used in canada and Pacific northwest where tree diameters were to much for most saws pulling full comp chains. They also help with using longer bars on otherwise underpowered saws,but they have only marginal success in hardwood. They perform best in softwoods such as pine or fir. The skiptooth chain can be jumpy in hardwood and will require frequent maintenance.
Most skip tooth chains are sharpened to 10 degrees and these are the chains I have been using for many years ripping logs up to 1500mm diameter hardwoods including oak, blackwood, messmate and redgum the full skip ripping chain provides better chip clearance and the chain runs cooler. However I would concede that a 30 degree skip chain could be used for cross cutting but as you mention they can be jumpy in hardwood which is what most of our native timber is. I use a full chisel 30 degree full comp chain on up to a 60" bar with no issues other than the weight!
How many cc is that? Im very impressed it cut the way it did. I ask cause i have a 45 cc echo thats a 20" bar like to go 24" to 30". Anyone know what 3.3kw converts to in cc.
Kw is a measurement of power. (One part of it) ... cc is the size / capacity of the engines combustion chamber.
20" bar is about all a 45cc saw should run. If you like echo they offer a 59cc timber wolf thatll pull a 24" bar well.
its not paint in the bar your chain is way to tight
nice car
Do you think I could run a 30 inch on a 3.1kw stihl 311?
know one way to find out, but I wouldn't.
Itd be a stretch for 2 reasons. One,its a clamshell design saw and only one bar stud goes into a metal housing. The other bar stud threads into a plastic housing. 2nd is the oiler on these saws may not provide enough oil to keep everything lined like it needs. You can give it a try though. I've seen some people run the Mike that when they were in a tight spot.
Did you do any modifications to your saw before you put the 30 inch bar on it?
Not any performance modifications, it has a non genuine muffler on it because I broke the original with a log a few years ago. Other then that it’s all pretty standard.
@@offtrackprojectsandmainten5681 ok cool I have the same saw and was thinking of putting a 28 inch bar on it but wasn't sure if it could handle it. Thanks for the video.
110% America Loving PATRIOT should be fine I think, I would definitely use the skip tooth chain though it’s great!
@@offtrackprojectsandmainten5681 ok thanks for the info. Are those Oregon bars just as good as the Stihl bars?
I imagine they would be pretty good, Oregon stuff is usually pretty good. This Longer brand has been pretty good for the money, not sure if it’s available in the US?
He has his chain way way way to fucking tight
Did you have to change the drive sprocket?
No I didn’t have to change the sprocket , I kept the standard 7 Tooth one.
@@offtrackprojectsandmainten5681 That's good to know.
not very impressive............. and you're also cutiing the life of that saw in half..................
