How Do You Measure a Chainsaw Blade and Chain?
Cullen BlakemanIs your chainsaw starting to seem dull and not perform as well? Looks like it’s time to replace the chain. In order to do this, you will need to know the length of both the chainsaw blade as well as the length and size of your chain. If you’ve checked out the manufacturers’ charts, they might seem a little overwhelming. But it really is pretty simple once you understand what’s involved in the length of the blade and chainsaw chain.
When you’re ready to replace your chain, the first thing to do is determine the size of your chainsaw bar. If you happen to have an Oregon chainsaw, this should be easy. Just check the first two numbers of the ten-digit model number that is stamped on the motor end of the blade. That’s your chainsaw bar length.
Don’t have an Oregon chainsaw that easily shows you the length of the blade? Then here are some tips for figuring it out yourself.
How To Measure Your Chainsaw Blade
You may wonder how do you measure a chainsaw blade. To determine what size your chainsaw blade is, you need to measure starting from where the bar comes out of the casing all the way to the end of the bar.
To eliminate any confusion, the words “blade” and “bar” are both used interchangeably to refer to the same thing … the long metal blade that extends from the motor casing and holds the chain that does the actual sawing.
For all manufacturers, chain saw blades are made in 2-inch measurements. Although the most often seen are the 16-, 18- and 20-inch sizes, you can actually buy chainsaw blades as small as 10 inches or as long as 42 inches. If your blade measurement doesn’t end in an even number, then round up to the nearest one.
Measuring A Chainsaw Chain
To measure the chain on your chainsaw, there are two things you will need to know … the number of drive links and the pitch of the chain.
The number of drive links actually determines the length of the chain. A drive link is simply a tooth on the chain. The pitch of the chain will also affect the size of the drive links.
The pitch of a chain is the size of the chain. This is the distance between any three rivets, then divided by two. Your chain pitch is important because it must match the pitch of the drive sprocket and sometimes the bar nose sprocket. The pitch should be stamped on the drive link.
To be more specific, a 1/4″ pitch chain might have 52 drive links and be 2.17 feet in length, while a 3/8″ pitch with 52 drive links would be 3.18 feet in length. The number of drive links has a direct correlation to the blade length.
If you have any questions, the manufacturer of your chainsaw or anyone who makes chains should be happy to help you figure out what you need to know.
