When should I Replace my Chainsaw Bar?


There are many factors that may affect the quality of the cut that we get from our chainsaw. But mainly there are two most important things that affect the same, they are the chain and the guide bar. Regardless of how much we maintain and look after it’s upkeep, the chain and the guide bar requires to be replaced because they are under constant load. So today we are going to share with you tips on when to replace the chainsaw bar so as to avoid any accidental damage from it. Apart from that replacing it will save us a lot of time as well as money in the long run and in case if we are in doubt, we can even go for swapping it out. Fundamentally there are two broad categories of the chainsaw bar, the sprocket tip and non-sprocket tip, that we will be discussing in this post.


Sprocket Failure

The very first sign to look out for is the sprocket which often gets worn out. It is because when we are cutting with often dirt and debris gets into it and that covers the sprocket bearings resulting in heating it up and seizing it. Sprocket failure is one of the most common reasons that we can find in the bar. In case if your tip sprocket bar is replaceable then the best way to fix it is by simply replacing the tip of the bar.

Bar Tip Failure

Another failure point that we can experience is with the actual tip of the bar. Now here it is not about the sprocket but the real tip of the bar. After constant use of the same, the bar starts to separate which results in a gap around the sprocket. As a result of which the chain get wedge deeper at the end of the bar seizing it immediately. If this happens there is no way to repair it and we need to get a new chainsaw bar by replacing the existing one.

Channel Wear

Another type of wear is the channel where which happens over time because of the friction of the chain against the bar as it moves. But we can slow down this wear easily by ensuring that the saws oiler is working properly, the oiler hole on the bar is not dirty and the channel itself is clean. If that is not the case and the channel is in a dirty condition and not getting proper oil, it will result in adding to the friction zone of the channel which will gradually widen and allow the chain to flop from side to sideAlthough there are some ways to narrow the gap unless we are professional or highly-skilled, with proper tools it’s not worth giving a try.

Rail Damage

We can get to see this type of damage typically at the nose of the bar and its heel. This type of Damage can be noticed in the form of uneven rail height. We can also alleviate this type of damage by making sure that a proper amount of tension on the chain is maintained as well as by giving it a flip over regularly.

Non-Sprocket Tip Chainsaw Bars

(a.k.a. hard nose bars)

We can also alleviate this type of damage by making sure that a proper amount of tension on the chain is maintained as well as by giving it a flip over regularly. Although the hard nose bar comes with long durability it does not mean that they are not susceptible to wear and tear altogether. Like the bar, this one is also prone to channel wear and rail damage. When this happens the hard-nosed bar tends to slow down the chainsaw somewhat. But when it comes to using a hard nose bar vs. a sprocket tip bar both have their pros and cons. To put it simply it’s about what matters more to us the speed or durability.
