Is 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.
The length of the chain will be determined by the length of your chainsaw bar. Some companies actually make this easy for you by including the bar size as part of the model number. Oregon chainsaws do this for you with the length of the bar as the first two numbers of the 10-digit number stamped on the blade at the end nearest the motor.
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
Measuring a chainsaw blade is actually quite simple. Just measure the blade from where the bar comes out of the casing, all the way to the end of the bar. No need to measure around the perimeter.
The blade and the bar are two names for the same thing. They both refer to the long portion that extends from the motor casing that carries the chain and is used for cutting.
Chainsaw blades are measured in two-inch increments. The most popular sizes are 16, 18 and 20 inches, although you may find some saws with blades ranging from 10 inches to 42 inches in length. If you don't think your blade ends in an even number, round up to the nearest measurement.
How Do You Measure A Chainsaw Chain?
The way to measure the chain on a chainsaw involves knowing the pitch of the chain as well as the number of drive links.
A drive link is simply a tooth on the chain and your chain's length is determined by the number of drive links (or teeth). The pitch of the chain also affects the size of the drive links.
To determine the pitch of the chain, simply measure the distance between any three rivets on the chain and then divide that amount by two. The chain pitch must match the pitch of the drive sprocket and also the bar nose sprocket. You will find the pitch stamped on the drive link.
As an example, 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. So the pitch affects the drive link size which affects your blade's length.
Still unsure? Just check with your chain saw's manufacturer or anyone who makes chains and they will be able to clear up any confusion you may have.
