Husqvarna chain saw doesn’t get oil to the chain

How to fix chain oil in a chainsaw

Saw made in 2010. I use it mostly in my summer cottage and on my annual trip in August in Karelia. Wouldn’t say I beat the shit out of it, use is more likely rare and sparing. I never built a log home with it. I have been cutting down a tree or a pole For the last year I suffer from such a misfortune: there is always a puddle of oil under the saw. Leakin’ from the chain grease tank. Changed pump two times, changed the rubber, where the pump piston is inserted. still leaking.In summer, a full tank can leak out overnight. By long experience it was determined that it was not the pump that was leaking but the metal strip that was under the “tire”. Behind it at the top there is a hole with a piece of PVC pipe inserted that goes into the oil tank.

Well, it’s always leaking. I tried to leave the saw on its side, I twisted it this way and that way No matter what you do, there’s a puddle of oil under the saw. Maybe whoever has experienced something like this? Can you really fix it or just suffer all the time?? Before, nothing was leaking.

Chainsaw chain lubrication system

To supply oil to lubricate the chainsaw chain, a special pump is used in the tool, which doses, depending on the number of engine revolutions, the lubricant to the saw bar.

Chain lubrication oil with high adhesive properties is used in the system, this is necessary to spread the oil evenly around the bar and keep it on the bar even at high chain rotation speeds. Let’s consider in detail the system of oil supply, implemented in modern chainsaws.

Travel tips

It is not enough to know how to solve problems with a broken or missing chain, you can always prevent it. Taking good care of your saw helps to extend the life of your machine and its parts. Therefore, it is recommended to follow the advice of experts:

• Regularly clean the air filter and lubricate it with oil. A filter should be changed from time to time.
• Each time before starting work, you need to check that all the nuts and bolts are securely tightened. Then the unit will not malfunction during operation.
• Both bearings and sprocket need to be lubricated.
• Clean the spark plugs regularly.
• Timely lubrication, sharpening and tensioning of the chain.

A quality chainsaw can last longer than the warranty period if it is properly maintained and repaired on time.

When the chainsaw chain slides, a lot of heat is produced in the bar groove as a result of friction. If there is no oil flow to the chainsaw chain, you must stop work and take all measures to correct the faulty lubrication system. The combination of heavy loads and overheating can lead to accelerated wear and early failure.

• All chainsaws and their electric counterparts are equipped with the same-type functional systems that can lubricate the bar, saw chain and its drive components.
• This unit comes standard with a reservoir from which the chain oil is fed to a fixed or adjustable capacity pump inlet.
• Further, the dosed amount of working fluid goes to the bar groove, where the saw chain shanks distribute it evenly over the whole chainring and the working surface of the driving sprocket rim.

Performance tires with a length of 400 mm or more come with a sprocket sprocket. Periodic lubrication of the bearing is done individually, after 6-8 hours of operation.

Layout of the lubricating system

Depending on the chainsaw brand, the details of the lubrication system may be slightly different structurally, but their total number and connection scheme remains the same.

The main components of the lubrication system are:

oil tank, usually located in the engine crankcase.

Lubrication system arrangement

Depending on the chainsaw brand, the parts of the lubrication system may vary slightly structurally, but their overall number and connection scheme remains the same.

The main components of the lubrication system are:

the oil reservoir, generally located in the engine crankcase.

principle of operation

The pump is the heart of the system. Its working principle is as follows. As the engine speed increases, the pinion mounted on the main shaft drives the pump shaft through a worm gear. In turn, the rotation of the shaft creates a certain pressure in the oil line, which makes the oil move through it towards the tire.

The end of the oil channel is at the point where the bar contacts the tool casing, where there is a longitudinal groove on which its oil channel falls when the bar is installed.

The groove is needed to keep the oil flowing to the guide bar regardless of how tight the chainsaw chain is. Simply put, no matter what position the tire is in when working, oil will flow into the tire through the slot.

Then the chain is involved in the lubrication process, on the links of which, depending on the chain model, there is either a groove or a hole through which the oil is dispersed throughout the bar. As engine speed increases, so does the oil flow.

Some chainsaw models are equipped with pumps that have an additional flow regulation, and if necessary, the amount of oil fed by the lubrication system, can increase or decrease.

This feature is quite handy, t. к. saves oil and prevents unnecessary waste of oil.

What can replace expensive oil?

Expensive compositions considerably extend the life of the saw unit. But some chain saw owners deliberately buy cheap alternatives to the original lubricant. They are more comfortable changing chain and tire more often than spending money on an expensive brand.

Proceed with the choice of lubricants should be based on their ability to protect the bar from chain friction. That’s why low quality is more trouble than it’s worth. If the original chainsaw oil is replaced by automotive oil, you should choose a lubricant composition with increased adhesive properties.

Among the budget options can be distinguished:

These options are great at low temperatures. Experienced sawyers recommend paying attention to the liquid for machines and equipment brand Enkor.

How to choose a chain

Choosing a chain will help you study their typology. Important criteria for distinction are:

• tooth pitch. This is measured in inches. The most common sizes are considered 0.325, 0.375 and 0.404. Each of these is selected according to the tasks at hand. The smaller the specified parameter, the lower the productivity will be, which means that you do not need to put a lot of effort. That is why it is necessary to buy a chain that has the right power for the chainsaw.
• the thickness of the tail, the driving link, which means that it is possible to choose the product for different tires. The 1.1 mm thick tail is only found on small chainsaws for household saws. The most popular size is 1.3 mm. Even semi-professional machines can be fitted with this model.
• Sawing depth and profile height. The performance of the machine depends on this parameter. There is always a way to increase the value by sawing down the stops next to each cutter. There are two options to choose from: 0.025″ (0.635 mm) and 0.03″ (0.762 mm). Having a high-profile chain makes the chainsaw aggressive and sharpening. Keeping the balance between high output and low vibration is easy with a product with a small bar spacing.
• Length of chain, bar and number of teeth. The choice depends on the chainsaw’s power output. And the best saws are not always characterized by an increased number of teeth and bar size.
• Types of cutting links. chain types by this characteristic: chisel and chipper. The first type is the best because of its straight cutting surface that enables it to cut evenly into the wood. It is difficult to sharpen these links and if there are even small deviations from the upper corners, chain performance will be reduced. Chipper ones have worse cutting characteristics, but they are more resistant to any kind of dirt and easier to sharpen.
• Chain link sequence. The model with one cutting link and two tails is popular. But non-standard variants are also possible: with half seam. only one connecting link is inserted between every second pair of working teeth, with a seam. a link is inserted between all neighboring teeth. This reduces the cost. But at the same time, aggressiveness and productivity are reduced, and wear increases, including chainsaw.
• How the material is sawn. Longitudinal and crosscutting products allow the bar to be driven longitudinally and crosscutting as needed. They differ in the sharpening angle of the cutting links.

• Cutting depth and height of profile. The performance of the machine depends on this parameter. It is always possible to increase the value by sawing down the limiters near each cutter. There are two options to choose from: 0.025″ (0.635 mm) and 0.03″ (0.762 mm). High-profile chainsaws are aggressive and sharpening machines.

This reduces the cost. But at the same time aggressiveness and performance are reduced, and wear and tear increases, including chainsaws.
• The way the material is sawn. Products with longitudinal and transverse sawing allows you to guide the bar along and across the fiber, depending on the need. They differ in the sharpening angle of the cutting links.

Using Waste Oil

Using used chain saw oil causes even more wear and tear on the mechanism

To save money, some chain saw owners use used oil. oil that has been drained from the machine. to lubricate the chain. But this leads to even more wear and tear on the chain, because this kind of lubricant works like an abrasive, only increasing the chain‘s friction.

The problem is caused by metal chips and sludge in the oil sump. It not only wears out the sprockets on the bar faster, but also deforms (and often tears) the saw chain.

If it’s necessary to use non-original chainsaw oil, but automotive oil, it’s necessary to use pure, unadulterated compound instead of used oil. But this should not be done routinely, but only in extreme cases.

Common malfunctions on the STIHL 180 chain saw

Faults and troubleshooting

Problems with the oil pump can be divided into two categories. One means no oil supply, the other one is leaking. Depending on the type of the problem and the main symptom, you need to take different actions.

No oil supply

If there is no oil supply to the saw headset, but you do not notice any leaks, it can be assumed that the plunger remains stationary. Why is the plunger standing still?? It may be worn out or the screw to which it is connected is not installed correctly. The plunger may be standing in an unnatural position, which is often caused by improper assembly of this assembly.

It is necessary to be guided by /-, special marks. Such marks, of course, can be lined up in the correct position, but the screw will not stand in the correct position (opposite). How to fix such a problem? Simply disassemble the pump and put the screw on properly. Sometimes it is enough to turn it to the “-” mark. The screw itself can’t get into place, that’s why it’s blocking the plunger’s movement.

How do you know if the plunger is worn out?? Pay attention to its end, or rather to the edge of its end that may be worn away. Then you don’t see the characteristic protruding part at this point. That spot with the whole edge will be about level. How to fix this problem? There are two possibilities:

If you choose the second option, do not forget to grind the shoulder in the center. Keep in mind that the pump will work after turning, but the oil flow is increased by shifting the plunger.

Sometimes there is another problem, when the oil is flowing, but the pump does not work as it should. Then you need to check the inlet and outlet hose. One of them might come off. If it happened to the inlet hose, oil will leak even when the saw is not started. If the outlet hose is disconnected, oil will be pouring out when the engine is running. Eliminate such a problem easily, it is enough to reconnect the hoses.

Leaking

It would seem that we have considered the cause of oil leakage. Yes, indeed, it happens sometimes because of disconnected hoses. But, this has nothing to do with the pump itself. So now consider the causes of leaks that are associated with pump failures.

Leakage can occur when the rubber sleeve ceases to provide a seal. The sealant may be badly worn or the sealant may not be installed as it should be.

Before you look for a new pump on your Partner chainsaw due to persistent leaks, remove the components and consider the collar, which may be installed with the collar turned toward the oil reservoir. If it is standing like this, turn it about 180 degrees. If you see that the seal is worn out, replace it with a new one. Of course, try to find the perfect collar. If you can not find it, buy a seal ring at the plumbing store.

If you still see leaks afterwards, examine the walls of the pump cylinder, which may be worn out. In that case, it is easier to buy a new pump.

Faulty oil pump

Regardless of the manufacturer, the lubrication system of any chain saw can malfunction.

chainsaw oil pump assembly

The nature of faults in the lubrication system can be different, and therefore before you begin repair it is necessary to determine the exact cause of oil leakage or its failure to penetrate the tire. If you exclude the possibility of mechanical damage, the following lubrication system failures can be identified:

• The line connection to the chainsaw oil pump outlet channel is not sealed;
• Loose fit of parts in the plunger system;
• Displacement chamber and ram size do not match;
• Lack of tightness of oil line with oil pump inlet connection.

It must be remembered that if the plunger system is not sealed and the lubrication tank is located above it, there will be a rapid leakage of oil (2-3 days).

It is quite easy to eliminate the oil leakage from a chainsaw when it has not been in use for a long time. You will need several screwdrivers and wrenches.
