Chainsaws, like cars, have parts that need to be replaced from time to time. The chain is a wearable part and will, therefore, also need replacing periodically. However, not just any chain can be used for any chainsaw, as they must be the correct length, pitch, and gauge for it to work with a particular saw.
Most commonly, the Stihl MS170 uses is a 3/8 pitch Picco, .043 gauge, 55 drag link chain. This is the most common size chain for the Stihl MS170 and fits the stock 16″ guide bar. The 16″ guide bar has been shipping with the MS170 for the past several years.
The second most common chain for the Stihl MS180 is a 3/8 pitch Picco, .043 gauge, 50 drag link chain. This chain fits the 14″ guide bar that some older Stihl MS180 chainsaws shipped with several years ago.
You can find the chains at your local dealer or an Oregon equivalent on Amazon thru the following links:
The 16″ MS170 chain can be found HERE ON AMAZON
The 14″ MS170 chain can be found HERE ON AMAZON
What’s Better, .325 or 3/8 Chain?
The debate between what size is better, a 3/8″ or .325″, largely depends on what you’re using the chain for and how large of a chainsaw you’re using.
Generally speaking, the 3/8″ pitch chain is better for cutting hardwood, while the .325″ pitch chain is better for softwoods and general-purpose use.
The 3/8″ pitch chain is also better suited for larger chainsaws as it can handle more power and torque produced by larger chainsaws.
If you’re unsure of what size or type of chain to use, it’s always best to consult your chainsaw’s manual or a professional.
Can I Put an 18-inch Bar on a Stihl MS180?
No, you cannot put an 18″ bar on a STIHL MS180.
The MS180 can only accommodate bars up to 16″ long. Anything longer than that will not work properly with the saw. The engine of an MS180 cannot generate enough power to drive an 18″ bar properly.
Do You Have To Use a Stihl Chain on a Stihl Chainsaw?
No, you don’t have to use a Stihl chain on a Stihl chainsaw. However, you need to make sure the chain you’re purchasing meets the specifications of your chainsaw and guide bar.
Not all chains are created equal, and using the wrong chain on your saw can damage the chainsaw, guide bar, and chain.
The easiest way to tell is by looking at the specification markings on the side of your chainsaw’s guide bar. The markings will tell you the pitch, drag links, and gauge of the chain your chainsaw takes.
You can then use these measurements to find a compatible chain from another manufacturer. Just make sure the chain you purchase has the same pitch, drag links, and gauge as what’s specified for your saw.
Will a 16-bar Fit My MS180?
Yes, a 16″ bar will fit your MS180. The MS180 is designed to accommodate bars up to 16″ long.
16″ is the maximum size bar that can be used on the MS180. Anything longer than that will not work properly with the saw. The engine of an MS180 cannot generate enough power to drive a bar that is any longer than 16 properly”.
You can install a shorter guide bar on the MS180, like a 14″ or 12″ if you want, but going any longer than 16″ is not recommended.
What Size Bar & Chain Does a Stihl MS180 Have?
The Stihl MS 180 uses primarily two guide bar sizes, 14″ and 16″. The most common size that has been shipping with the MS180 for the past several years is the 16″ guide bar.
The 14″ guide bar was used on some of the older MS180 models and can still be purchased as a replacement part.
The chain is a 3/8 pitch Picco, .043 gauge, 55 drag links (16″ bar) or 50 drag links (14″ bar).
