It is essential to have a chainsaw chain that fits perfectly. If the chainsaw chain is too tight or is it to lose, this can be very dangerous. To save yourself from accidents which can result horribly, make sure that you measure the length of the chain to have the right size. In this article, we will tell you that how can you measure the chains of the chainsaw. But before we start, take all the safety measures by making sure that your chainsaw is turned off. Make sure to unplug your spark plug or the battery to be on the safe side.
In measuring the chainsaw chains, the following steps need to be followed:

CHAIN

Step 1: Measurement of the bar

Before you start measuring the length of the chain, you need to know the measurement of the bar of the chainsaw. You will measure from the point where the bar emerges to the end of the bar. The distance between the two points is the length of the bar. You can do this measuring with the help of a tape measure. The number you get, you can round it off to the closest even number if the measurement is uneven. You will observe that the most common measurements would be 16, 18, 20 inches, and it could be more or less.

Step 2: Counting the drive links

When you are done with the measurement of the bar, you need to measure the drive links of the chain. All the drive links join together to form the chain so to find the length of the chain, you need to know the number of the drive links. Lay the chain flat on a flat surface so you can easily have a look at the drives. Chain’s drive links are also called the lugs. These links grab the drive cog from beneath and then add more power to the chain. You have to count the number of drive links. The drive links can be 56 or any other number, make sure to calculate them

accurately. You can do this step more than once to make sure that there is less chance of error.

Step 3: Determining the pitch of the chain

In this step, you have to do the following things to get the right measurement of the chains.

Measure the distance between the rivets: You have to measure the distance between any three consecutive rivets that hold the chain together. You have to measure the distance from the centre of one rivet leading to the centre of the third rivet. You will be able to find the rivets between the drive links and the cutters.

Diving by 2 

 To find the pitch, you have to divide the measurement by 2, the size that you have taken between the three consecutive rivets when divided by 2 gives the tone of the chain.

Step 4: Sum of the measurements:

The sum of the two sizes, which is the pitch and the number of the drive links is the length of the chain is that you need to have the right length.

By following these steps, you will be able to find the right measurements of the chainsaw that you are looking for. However, chainsaws have this information written on them, now a question arises, where to look for this information. At the back of the bar, the information that you may need be stamped on it. So, you can just read it from there, but if in case it is not there, then you will have to take the measurements yourself. By taking the measures yourself, you will have a good idea of how many drives links you need for the chain of the chainsaw. With this, you will be able to make your chainsaw chain with the chainsaw chain roll.

Some people also take help from the professionals, or they use a bar and chain calculator to get the right measurements. But following the method mentioned above is also easy. You will be able to get the desired sizes with it. By understanding the correct measurements, you are all set to get a new chain.
