Chainsaw Bar Oil Hole: Fix In 8 Easy Steps

Chainsaw Bar Oil Hole

Every chainsaw has an oiler that keeps the chain lubricated. If you are a new stoner, and find the chainsaw bar oil hole clogged and not correctly working, you probably need to know how to fix the problems.

While looking for solutions, you need to know how the chain saw bar oiler works. Almost every modern chainsaw uses an automatic oiling process. First, the chainsaw bar oil goes into the oil reservoir.

Then the lubrication is disclosed onto the bar constantly through a hole in the bottom of the bar. This bar hole needs to be constantly cleaned to ensure that your chainsaw is working correctly. Otherwise, you may find problems like bar oil blockage, bar oil hole clogging.

The oil must be passing through the bar hole properly. When the pump sends oil through the bar hole and discharges it onto the bar, it distributes oil through the body while running.

Now, let’s see how to fix the problems in detail.

Most Common Problems  Of Chainsaw Bar Oil Hole

Here are some of the common issues –

Chainsaw Bar not Getting Oil Through the Oil Hole

A chain oiler automatically pumps oil into the bar picked up by the bar surface later. The most common because a chainsaw oiler stops working is that the chainsaw bar oil hole is probably clogged.

Also, if your chainsaw’s boiler is not working, it can further cause smoke while running.

Leakage in Chainsaw Bar Oil

Otherwise, in very exceptional cases, there is nothing to be afraid of oil leaking. Most often, an oil leak occurs as the chain runs at a very high speed and the oil drains from the saw body.

But in fewer cases, oil leaks when you forget to fill the cap after using the chainsaw. Then, as heavy pressure runs through the chainsaw’s body, the leaking continues even after it is turned off.

Chain Guide Bar Spray

The oil pump provides a continuous flow into the surface of the bar. It is familiar to identify chain oil inside the groove of the bar. The oil may flow downwards to the exterior below the chainsaw.

The Chain Is Dull Quickly

If you find your chainsaw’s chain dull very quickly just after running, it could be a couple of things. First, maybe you are applying too much pressure when you file.

Second, when you run the chainsaw too fast, it will cost more oil from the oiler through the oil hole and make the chain quickly.

Fixing Chainsaw Bar Oil Hole – 8 Easy Steps

Fixing Chainsaw Bar Oil Hole

Here are the steps you need to follow –

Step 1 – Diagnose the Problem

Before fixing the problem, make sure you diagnose it correctly. Unfortunately, there are few easy ways to diagnose that your chainsaw bar oiling system is confronting problems.

At first, Make sure that the oil tank is sufficiently filled with oil. Then turn the chainsaw on and allow it to warm up for few moments.

After depressing the throttle, hold the chainsaw bar close to cardboard or a piece of fresh wood. If you don’t see any sparking of the oil on the surface of the board or wood, then the chain bar is not properly lubricated.

The oil is not passing through the oiler hole to the surface. Maybe there is a blockage in the bar oil hole, or it is clogged off.

Step 2 – Increase Oil Output

In most of the chainsaws, there is a dial with a plus sign and a minus sign. If you find that the oiler is not providing enough oil to lubricate the bar, turn the dial towards the plus sign, increasing oil output.

Then turn the chainsaw back on again and warm it up for the performance of the test again. Even if the problems remain, let’s try something else.

Step 3 – Remove the Clutch and Bar

Remove the clutch cover and take the chain off the bar of your chainsaw. If you find the chain damaged or scraped, that may be the issue of the problem.

Then replace the chain with a new one or repair it. While replacing, make sure that you clean the bar properly and make it free of dust.

If the chain looks OK, then it’s time to clean the outlet port of the chainsaw.

Step 4 – Check the Oiler

At first, check the oil lines to check if there is any crack or hope. After that, clean the oil tank properly after draining. Hopefully, it will fix the primary problems. If it doesn’t, don’t worry. Let’s try further steps.

Step 5 – Clean the Oil Outlet Port

The outlet port ensures lubrication on the bar’s surface through the bar hole located just behind the chainsaw bar.

If this part of the saw is not clean, nothing to be surprised by when your chainsaw is not correctly working. You can block this little part with sawdust. So make sure you clean this vital part.

Step 6 – Clean the Chainsaw Bar Oil Hole

The bar hole, located at the bottom of the chainsaw, may create the leading cause of trouble if it is not regularly cleaned from sawdust. The Bar hole ensures that oil is passing from the oiler to the surface of the bar.

You can clean this out easily using anything solid and thin that will fit into it. Brush as much as you can on both sides of the bar hole as the chainsaw bars are reversible.

Step 7 – Clean the Bar Groove

The bar groove located around the bar ensures that oil reaches every part of the chain. When oil passes through the bar hole and tries to lubricate the bar’s surface, a dust-up bar groove will obstruct the oil.

You can clean the bar groove with a gauge tool or almost anything that fits in it.

Step 8 – Put the Parts Back Together

Once you followed the upper steps thoroughly, you just need to reassemble the chainsaw. Then, put the chain back on the bar after ensuring that the chain is in the right direction. Finally, you must solve the problems you are facing after all these steps.

If you still find the problem existing, then it’s time to hand over your chainsaw to an expert, and most probably, it’s not a problem with the oiler or the oil hole.


Why My Chainsaw Bar Is Smoking/Overheating?

The probable causes of overheating or smoking are the insufficiency of air to the engine or lack of proper lubrication of the chainsaw bar.

Make sure the engine is getting enough air, and the bar oil hole is clean of sawdust.

Can I Drill An Oil Hole In My Chainsaw Bar?

If it is not mandatory, try to avoid drilling a hole in a chainsaw bar. If you drill anywhere from the bar, it will fail a standard drill bit, and you will make it damaged.

But if drill becomes the only option, use an Aluminium Oxide to make sure you are drilling in about the same shape and angle as a regular bit.

What Happens To A Chainsaw Without Bar Oil?

Serious friction may take place without lubricant on the surface of the bar. This is because the chain moves over the chainsaw bar at a constant rate.

A slowed-down chain with excessive fuel burning refers to a lot of friction between the chainsaw bar and the chain.

As a result, a lot of heat is produced and may cause severe damage to your chainsaw bar.

Chain oil makes sure that everything frequently moves while it helps cool the chain and bar. A chainsaw without bar oil may break down and cause damage to the engine.

Bottom Line

Taking proper care of your chainsaw will enlarge your lifetime. You can quickly fix the most common problems regarding chainsaw bar oil hole at home as we assume that readers have learned about fixing the problem with chainsaws.

If you think your chainsaw bar is not getting enough oil and there is a problem with the bar hole, groove, or oiler, please follow the solutions. They won’t require hard labor or expense.
