Stihl MS 311 Using 36 Inch Bar Bucking Water Oak Rounds

[@danstefancic8414]

I did the same setup on my 311 but to save the powerhead sprocket as well as the bar sprocket I add molyslip (MOS2) which is great for ultra heavy load/friction. Note that you can't simply add the molyslip to the oil tank. I add 50ml to 3.78L of light Stihl barchan oil. The bar chain guides and all the sprockets look brand new after 5 years and dozens of bush quarts.

I got muffer mod bigger carb and jet plastic clamshell saw pulling so hard it was melting plastic, but I run 32/1 fuel rich so it won't rev, but it sings in the cut under load and won't bog in post Oak.

[@tubewaldo]

Wish Sthil bars had a grease port on the tip to help keep the sprocket cooler.

[@iraagans3144]

Older bars from stihl do.

[@ciphercode2298]

Idk,I've never had one fail. I'm not a logger,but cut 8 cords of firewood a year. I've got a couple bars goin on 10 years old. Dress them and flip em every few outings and keep your oil flowing good.

[@jameskolbe8]

I cut up a standing dead locust tree and my ms311 did an awesome job. Couldn't be happier

[@pauljaney21]

Love the firewood videos keep them coming

[@stephanmackie5281]

You’ll burn that plastic saw up if you continue doing this. Definitely doesn’t oil anywhere near what’s acceptable. Guarantee your cylinder temps are approaching 500 degrees during long cuts. Bad business there.

[@ciphercode2298]

Yes and no. I used one on my Alaskan mill for 4 years before I stepped up to an ms441c. It did run pretty darn cutting 8 ft long oak slabs,but it held up ok.i still cut firewood with it occasionally and while I was rebuilding my husqvarna 550xp I checked the compression unit just because I had my gauge out and handy. It still has 150psi of compression and its 10 years old or more now.

[@dirtbikedion3233]

Who cares bro it’s a saw just go rebuild it who cares how other people use there tools

[@05xlt]

This is the chainsaw equivalent of putting super swampers on a camaro. The video would have been 10 min or less with a 20” bar.

[@markyakubovsky3380]

LOL- that visual is hilarious.. I run a 20 inch bar on my MS311 and it cuts fast and efficient.. I'm no expert, but I'd be afraid of cooking a piston with a 36 on it- even if it was richened up.

[@timtorkelson7201]

I have a 311 in addition to 462 and 36" is way too much bar for that saw!! 18-20" perfect.

[@richarddodds9326]

My NS892 pulls a 36 really fast.

[@oysterman1223]

Did you have to change the original sprocket to accommodate the 36 inch chain or is it the same 3/8 pitch?

[@cvmikeray2]

Same sprocket.

[@oysterman1223]

Thank you for providing the information!

[@oysterman1223]

I’m running into a chain lubrication problem. The chain and bar are overheating and seizing up. Took it by to local power shop to see if they could increase the flow rate but that was a no go. Are you experiencing the same problem?

[@cvmikeray2]

@@oysterman1223 I dont run the 36 inch bar all the time. I only use it for a few cuts. I have seen issues even with my shorter bar having oiler issues. I need to see if trash has gotten in the oil case and stopped up the hole.

[@oysterman1223]

Thank you for the information

[@jcsawshop]

It's now 2 years later. What went first? The clutch or top end? That poor thing is struggling. You should be aroung 9k in the cut, not 4k.

[@cvmikeray2]

Still runs like a champ.

[@chrisp556]

I'm surprised that chain stayed on. The chain getting to hot with the lack oil. That 391 doesn't put out enough oil for that big of bar.

[@stevenmiddagh6265]

That's a 311

[@goodolbiker]

They recommend 20" as probably the ideal size for the ms311 but I bought mine and it came with a 25" bar directly from Stihl and it rips revs high in a cut. 36" seems pretty boggy.

[@glennllewellyn7369]

Yep. Ta. Australia

[@kevinc.8869]

Hello, may I ask where you got those buckin spikes? My 311 has the little wimpy ones.

[@cvmikeray2]

It is actually off of a 660. Easy to slightly modify to fit the 311

[@Jeffrey-hi1ot]

And also with a 25 inch bar you have 50 inches of cutting space

[@devinmccloud]

There is a reason the max bar size is 20". It works with a 36" bar but you will greatly decrease the life of the motor every time you use it.

[@Anonymouso283]

The max size bar is a 25 inch. Only time a Stihl will break is bad operation of the user. Use her right, she’ll last forever.

[@devinmccloud]

You are correct max size is 25". They come standard 20" stock. Stihl is the best chainsaw hands down. You would have to adjust the oil output for a bigger bar. I still would not recommend heavy use over 25".

[@Anonymouso283]

@@devinmccloud I completely agree. I, currently, own an 11 year old Stihl MS290 (20 inch bar.) Not once has she broke on me. Yeah, for the the huge trees I cut, I have to cut on the other side, but it’s fine. No biggie. I live next to huge trees, and own 15~ acres. Especially water oaks are the ones that fall once a week. Used and abused the shit out of her, and she still runs. I’m just wanting another saw for the fuck of it at this point. Highly thinking of getting the MS311 25 inch. Of course I’d get a Stihl, because I’m a Stihl fanboy. Yeah, people love their Husqvarna’s and Echo’s and shit, but they’re missing out on the Stihl powaaaa! And… Reliability.

[@ianjones654]

Good news

[@maplenut0420]

That bar is way to big for that saw, you can just see and hear how hard it is struggling to gain the R's and you never even approach hitting the top end because it just to much chain for that little saw to be turning. Yes it may cut but there is a reason they give you max bar lengths for saws, so unless you want to greatly reduce the life of that saw put the 20" bar back on.

[@cvmikeray2]

Not everyday use. I was showing it will make the cut if needed. I have a 500i for the big stuff.

[@Jeffrey-hi1ot]

All you need is a 25 inch bar for at saw you are killing that motor on that chainsaw

[@woofy548]

that's to much chain for that saw. You should go with a 20" and let her rip.

[@e954rr2]

That poor saw

[@kennytheguitarfanatic054]

Nice video and great saw but i think that a 20 inch bar will cut faster with less strain on the saw a 36 inch bar on that saw could hurt the engine in due time like put strain on the rod bearing. I have the ms 391 and have found that the 20 inch bar cuts faster in big wood over 30 inches just line up the cuts .But this was a cool video.

[@cvmikeray2]

I do normally run a 25 inch bar. Just showing you could run the 36 if you needed it. I like to keep it with me just in case.

[@kennytheguitarfanatic054]

@@cvmikeray2 That is cool idea

[@neilmoore3856]

I have an older 311 I have a long bar for and it cuts way faster with a skip tooth chain than it does with a the loaded one. It doesnt load the saw down as much and the rpms stay up higher in the power.

[@kennytheguitarfanatic054]

@@neilmoore3856 That is a good idea i tried to get a skip or full skip chain from stihl but they discontinued them i guess have to get an Oregon chain

@@neilmoore3856 I thought that would be a good thing to try. I'll see how one works. Thanks!

Sure it would!!! 311 works in a pinch though.
