Thank you for these very well done instructions. It was a huge help to me, not for switching out the bar and chain, but for putting my saw back together again. It had jammed. When I went to remove the cover to inspect the chain, a screw fell out. I could not figure out where that screw came from. It was that single screw you show in the video which holds the tensioner onto the bar. The rest of your instructions were most helpful too as the saw has not seen much use and so the chain does not need to be replaced yet, so I never removed the cover to look inside. Again, thank you. Keep up the good work!

Great video as usual. Just did this to my MS170 with an Oregon set with a second saw getting a 16" Stihl set. For your followers, the use of the word gauge is misleading by the saw people. It is not like wire gauge or sheet metal gauge. It is the actual thickness of the web in inches, like 0.040" 0.050" and 0.063" Easy to measure with calipers or micrometer. I was thinking of going 18" on the second saw but even with the 14", the saw prefers dry wood and straight cuts. But I still love it. The important thing for the small engine is to let the RPMs rev up and don't bog down the engine with your cutting pressure.

*I put this same bar on my 1973 stihl 015 and it cuts much faster and better than the old 1/4 043 stock bar and chain. I had to change the spur gear and oil pump gear to 3/8 but it was well worth it. Thanks for all your awesome VIDS.*

I did the same thing with my 170. I used a 16" bar and chain with .063 gauge. Works real well. I think the 170/180 is an underrated saw meaning it has more power than is advertised.

Hi , thank you for the video . I have a ms180c that was due for a new bar , I upgraded to the heavier bar and chain and couldn't be happier , the heavier chain just does not wear out nearly as quickly . I also was having troubles with the easy start system so I bought a pre assembled side cover rope start for the ms170 and it was a 5 minute bolt on and requires no extra effort to pull since the engine is so small . I also replaced the chain adjustment with the side cover / bolts and adjuster from a ms170 . All the parts are on amazon for little money and its been a much more pleasant saw to use . Thank you for your video and reader comments .

Don, I learned something that is applicable to this video. The bar and chain on an ms 241 are the same as on a 180C with one exception. The 241 uses a .050 gauge chain, instead of an .043 gauge chain. Both are 16 inch, 3/8P chains. Instead of dropping down to a 14 inch bar, you can use the 16 inch bar for the 241. I have not installed the bar and chain off my 241 on my 180 but I am sure it will work. I would have already done it but my 180 has that easy adjust crap on it, which I hate. I can adjust a side adjust a lot faster than that easy adjust crap. Another reason I traded in my ms 181cbe when I got my new 241, which I love. You might want to do a video on converting the easy start and adjust saws to normal start and side adjust. The only redeeming features these saws have is the primer bulb and I always forgot to press , anyway.

Thorough explanation. To protect your fingers/hand from being cut should the chain jamb when rotating the chain by hand, only move the chain in the direction of travel not back and forth as was demonstrated in the video. Excessively worn sprockets or burrs on the drive links after a chain derailing are notorious for causing the chain to jamb.

Hi, Donyboy, thanks for your excellent videos. I have a Stihl MS 261 which came with a 20" bar, .325 pitch and .063 gauge. I want to install a 24" bar. From what I can tell (correct me if I'm wrong) for a 24" bar I have to go to a .375" pitch. Will I need a different drive sprocket? I need the 24" bar to Alaska mill a tree - kind of a one time project. What are the Stihl part numbers I would need for the bar, sprocket, and chain? I thinkI would prefer a less aggressive chain rather than full chisel. Thanks and let me know if there is a way to help support your channel.

If I was to buy a 180 then eventually perform this upgrade when the original 0.43 is warn, what size filing kit would you recommend. Would a file that suits 0.43 also be compatible with 0.50, or would you need to get separate files? I would not doubt buy a filing kit when purchasing the saw so would like to know if I can get one that suits both gauges. Keep up the great work, very clear and informative videos.

TheNorthener Yeah I commented on the fact that if you increase the gage size you either need to decrease the bar length, not extend it. These less expensive saws are probably engineered to run at peak performance with all parts stock. Iffin you create more drag by increasing chain bulk and cut, you should downgrade the length to keep engine doing it's best to perform well. Most tools are designed to only do with what they are sold with, unless you make improvements in engine output. They will run, but like you said, bog easier, wear out faster.

Because of the larger gauge chain, there will be more resistance on the bar. So a shorter bar will reduce that resistance and prevent any potential lose of power. I ended up going with a 12” bar instead of the 16” for that very reason.
