10 Simple Steps on About How to Measure Chainsaw Bars
In today’s society, it is important to know how to measure a chainsaw bar for your own safety. Here’s what you’ll need to do in order to find out what size of chainsaw bar you have:
Step 01: Check Your Owner’s Manual
The first step is to unplug the chainsaw (obviously) to measure a chainsaw bar. You should also check your owner’s manual and see what size of bar your saw requires. You can then use this information throughout the rest of the steps on how to measure a chainsaw bar.
Step 02: Find Out Where You Need To Take Measurements
You should know where to take your measurements from. If you have a 14-inch bar, measure from the middle of the bar hole to the tip of the teeth on both sides. Bar length is 15 inches bar longer and will be measured from one side to another.
It’s important that you only measure the saw-do not include any extension bars that you may have. When a bar measures 18 3/4″ in length, it has a called length of 20″.
Step 03: Gather Your Measuring Tools
In order to measure the chainsaw bar, you’ll need a ruler or a tape measure. You should also have a pencil and paper so you can write down your measurements as you go.
Step 04: Unscrew the Bar Nut
The next step is to unscrew the chainsaw chain bar nut. This is important so you can measure and see what size of chainsaw bar you need. You should be able to easily unscrew this with a wrench or screwdriver.
Step 05: Measure Cutting Length
Once you’ve figured out what size of effective cutting length or called length you have, write it down. Make sure to measure the effective cutting length which is measured from one side of the teeth to another. For example, an effective cutting length for a 14-inch bar is a 14-inch cutting length.
Step 06: Measure True Bar Length
Although you may have the size of the chainsaw bar, it’s important to measure the “true bar length.” This is the length of the bar that emerges with no attachments. Put a metal ruler against the flat part of the bar for this bar to enter.
Step 07: Measure Depth of Drive Link
The depth of the drive link is the depth of where it goes in. You should use a ruler or tape measure to find out if you have .404, .325, or .300 inch. These numbers are located on the right side of the bar usually.
Step 08: Record Your Measurement
Now that you’ve finished measuring your chainsaw bar, it’s time to record all of your measurements. Write down the length of the cutting teeth as well as where you took each measurement from. This will be important so you can find the right size chainsaw bar for your saw.
Step 09: Calculate Blade Length
Now you can calculate what actual length size chainsaw bar you will need by adding your two measurements together (length plus depth).
If your chainsaw doesn’t have a depth chain gauge, you can estimate the depth of the bar by dividing your length measurement by two. That is also what will need to be done for saws that don’t have a chainsaw blade length wear indicator.
Step 10: Purchase a New Chainsaw Bar
If your number falls within the range of chain measurements sizes for the chainsaw bars that are available, then you’ll be ready to purchase a new bar. You can also ask the store clerk if they have any other chainsaw bar sizes for your saw.
Now that you know how to measure chainsaw replacement bar, it will be easier for you to find the right size for your saw. Be sure to take accurate measurements and write them down. This will ensure that you won’t have to repeat this process the next time you need to change your chainsaw body bar.
