I have always noticed if you keep the same settings for both left and right cutters, they do not look to be the same length. It probably does not make much difference after the first sharpening, but I always believed it was best to keep the cutters the same length. If the right hand cutters are shorter than the left hand cutters then adjust the rails so they move closer to you.
I sharpened them back to the right shape, but just touched up the teeth facing the other way since they were still in good shape. So now I have half the teeth on the chain noticeably shorter than the other half. I’m hoping that the longer teeth will just do more work for a little while and I’ll slowly sharpen them all back to the same length, but I have no idea.
Not only do the cutters get lower as you grind them back, they become narrower. A cutter that is shorter, providing its raker clearance is correct for its length will take just as deep a bite, but being narrower will not cut as wide, then the next tooth that comes along has to plow into a bit heavier share and it shows up as more roughness on the exposed cut ends. The long tooth that is sporting a short raker will jerk things around much worse and create vibration and a rough cut.
do chainsaw teeth need to be the same length Related Question:
At what length of the cutting tooth should the chain be replaced?
The chain sprocket must be replaced if the depth of the wear marks reaches about 0.5mm, i.e. the wear limit. A seriously worn chain sprocket can cause the chainsaw chain and guide bar to wear at an increased rate, as well as reducing cutting performance too, so it’s important to keep an eye on.
How do you measure a chainsaws teeth?
To find the called length of your chainsaw bar, measure it from its front tip all the way back to the cutter closest to the body of the saw. Round this measurement up to the nearest even number in inches. For example, a bar that measures 18 3/4″ will actually have a called length of 20″.
How long should a chainsaw blade be?
The standard blade sizes for medium- to heavy-duty chainsaws are 14 to 18 inches, with engine displacements of 40 to 50 cc. Heavy-duty saws with long blades are adequate for heavy yard work, though in many cases they tend to be overkill and can actually hinder you on a small job.
How should the teeth on a chainsaw look?
The teeth must be pointed to the right on the top of the bar, when properly mounted. On the bottom of the bar and heading back towards the chainsaw drive sprocket, they must be pointed to the left.
Can you change bar length on chainsaw?
Replacing your chainsaw bar will require a few measurements. Most chainsaws can operate up to three different bar sizes. Guide bars are measured in length, from the tip of the bar to the heel, and range in size from 14 to over 40 inches.
Is it worth sharpening a chainsaw chain?
Sharpening your chainsaw chain is definitely worth it as a sharp chainsaw chain is easier to work with. It takes less effort to cut through wood and your chain will make cleaner cuts with sharp blades. A chainsaw chain can be sharpened multiple times without much of a cost.
How do I know what size chainsaw I need?
The usual guideline is to choose a chainsaw with a bar that is two inches longer than the diameter of what you need to cut. For example, if you need to cut a tree that is 10” across, you will need a chainsaw of 12”.
How do I know what size chain I need for my chainsaw?
To get the correct size, simply count 3 rivets on the chain and measure the distance between them from the centre points. Now divide this by half to get your size. As an example, three rivets that measure ½ an inch across divided by two gives you a pitch of a ¼ inch.
How big of a tree can a 20 inch chainsaw cut?
A good rule of thumb is that the diameter of the trees you cut regularly should be no more than twice the length of the bar on a chainsaw. That means a 20-inch chainsaw can handle a 36-inch tree (remember, effective cutting length is roughly -2 inches of the bar length).
How long should a chainsaw chain stay sharp?
A chainsaw may only need to be sharpened once a year if it is rarely used, but a tool that is frequently used will need to be sharpened regularly to ensure that the blade doesn’t get too dull. On average, a chainsaw blade will retain its sharpness for about 3 hours of actively cutting through wood.
Why is my chainsaw blade smoking?
This most commonly is a result of a dull chain and exerting to much pressure on the bar and chain trying to make the chain saw cut. This could also be either a lack of bar and chain oil ( tank empty, restricted oiler hole ) or an inferior type of oil that is being slung off the chain and not lubricating.
How many teeth does an 18 inch chainsaw have?
It’s an 18″ which takes 72 drivers of .
Can I put a 20 inch bar on my 18-inch chainsaw?
Changing the bar and chain on your 18-inch chain saw to a 20-inch size will enable easier cutting of larger trees and branches. Larger chain saws cut through thicker trees and limbs.
Can you put a 18-inch bar on a 14 inch chainsaw?
Different Bar Sizes A Poulan 14 chainsaw can operate with a bar that’s 12, 14, 16 and 18 inches length. However, a larger bar may not always give the best cutting performance.
Why does a chainsaw cut crooked?
One major reason a chainsaw curves to either the right or left during a cut is that it was unevenly sharpened. The unequal teeth of the chain cause it to take a different-sized bite into the wood. What is this? The uneven sharpness of the chain is mainly due to manual sharpening, especially with the use of a file.
