Why not oil arrives on a chainsaw chain?

If in the process of not oil arrives on the chainsaw chain, you need to find the cause of the problem. In fact, the reasons that affect the myth process, you will like a lot. You should disassemble the chainsaw and identify the main problem. The likely premises of this process will be described below.

Due to the lack of oil supply to the circuit during operation of the chainsaw, you will like several reasons for identifying them, you need to disassemble the chainsaw.

Likely prerequisites for non-receipt of fuel

Oil on a chain can not come only in the presence of 2 breakdowns. These include:

  • tasks with air leaks;
  • drive breakdown oil pump.

The main characteristics of the chainsaw chain.

The main cause of the breakdown is air leaks. This can happen due to depressurization of the oil hose during operation of the chainsaw. In such circumstances, remove the hose from the hole. This must be done in the area where it is connected to the crankcase. Then the hose sits on the sealant and is installed in its usual position. If this did not help, then elasticity was most likely lost. For the upcoming operation of the chainsaw purposefully change the hose.

2nd reason. drive failure oil pump. In common people, this part is called a worm. When the drive fails, the oil will finish feeding to the circuit. The oil pump drive is a round plastic ring with grooves inside. The constant introduction of the chainsaw leads to the wear of the internal parts, and as a result there is a puncture of the iron hook located inside the drive. After this breakdown, the oil stops flowing to the circuit.

Chainsaw fuel system: 1. fuel filter, 4.5. carburetor, 3. manual preparatory pump.

If the carburetor is correctly adjusted, the fuel will be consumed in an acceptable volume. Otherwise, it will end very rapidly.

Slow reduction of fuel in its operating time Sawing is a common process. If it is absent, the chain is not lubricated correctly, so working with a chainsaw will work well. It is necessary not only to be able to eliminate breakdowns, but also to identify them without the help of others.

Change the flow of fuel there is an option manually. The correctness of the lubrication complex of accounting programs is determined by the method of presenting the tire. If oil splashes appear, it means what remains to be done to our client correctly.

The chain can always be perfectly lubricated. This will avoid smoke and the upcoming failure of the entire chainsaw. If the oil leaks or does not flow at all, you need to identify the cause of the breakdown. Operating the tool before repair is not recommended.

When choosing fuel, you need to do it right. The desire to save leads to the fact that the circuit quickly burns out. To avoid unpleasant consequences, you do not need to choose the oil, which is produced by China. Preference should be given to unusual firms. According to their own price category, they are significantly higher, but their quality is better.

Resolving Circuit Service Issues

During the operation of the chainsaw you need to constantly look for chain lubrication. Since this part works in the most languid criteria. The chain undergoes constant overheating, dust and abrasive particles get clogged there. This negatively affects its life. To correct the situation allows a special grease. It is fed to the chain from the tank, thereby ensuring unimpeded operation.

If in your operating time no lubrication occurs, the highest possibility of overheating remains. When no oil comes in, the chain begins to stretch. With all this, there remains the possibility of jamming or spontaneous jumping off, and as a result, a person may get severe injury.

The channels through which the fuel is supplied must be clogged with small particles, therefore it is purposeful to clean them from time to time. It is important to watch the oil level in the tank. Debris in the channel becomes a frequent prerequisite for the failure of the chain brake. This can be bad for your work.

Permanent cleaning of the channels and general care of the chainsaw will allow the tool to work for a long time.

However, what to do in this case, if our client is left with tips that are followed, and the oil continues to flow. You need to make sure the chainsaw is working properly. It is entirely possible that it was not properly assembled. If the breakdown was not detected, it is recommended to take it to the workshop. Sometimes it is necessary to change the pump, but this must be done provided that the saw is brand new. Old tools leaking due to deterioration of the tank.

The current state of the chainsaw is able to evaluate only special. In the absence of knowledge or insecurity in one’s own strengths, it is better to entrust a tool repair to a specialist.

One of the important chainsaw systems, work without which is impossible, is the system of forced lubrication of the chainsaw chains. It’s no secret that at the time of the saw’s operation, the chain abrases on the chainsaw tire, which causes it to heat up and premature wear. To mitigate friction, the chain mechanism must be constantly lubricated.

The system uses oil to lubricate the chainsaw chain, which has improved adhesion properties, this is necessary for uniform distribution of oil around the entire perimeter of the tire and hold on it even at high speeds of chain rotation. Let us consider in more detail the oil supply system implemented in modern chainsaws.

Lubrication system device

Depending on the brand of the chainsaw, the details of the lubrication system may vary slightly constructively, but their total number and connection diagram remains unchanged.

The main components of a lubrication system are:

  • An oil tank is usually located in the crankcase.
  • The filter element is installed in the tank.
  • The oil pipe is a small diameter hose made of oil resistant rubber.
  • The heart of the system is the oil pump.
  • Worm gear gear transmitting force from the engine to the pump.
  • Chainsaw tire, it can also be considered an element of the lubrication system, as it has special holes for oil supply, by the way, the chain itself is involved in the transportation of oil and accordingly also has some elements designed specifically to provide lubrication.

Principle of operation

The main unit of the system is the pump. The principle of his work is as follows. With an increase in engine speed, a gear 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 causes the oil to move along it towards the tire.

The end of the oil channel is located at the place where the tire contacts the tool case, where there is a longitudinal groove onto which the oil channel enters when the tire is installed.

Grooving is necessary to ensure that oil is supplied to the tire, regardless of the degree of chain tension of the chainsaw. Simply put, no matter what position the tire is at the time of operation, oil will flow through the groove through it.

Further, a chain is included in the lubrication process, on the links of which, depending on the model of the chain, there is either a groove or a hole through which the oil is dispersed throughout the tire. With an increase in engine speed, the oil feed rate also increases.

Some chainsaw models are equipped with pumps that additionally have a capacity control, and if necessary, the amount of oil supplied by the lubrication system can be increased or decreased.

This function is quite convenient, because it allows you to save and not to waste extra oil.

Lubrication system malfunctions and how they are eliminated

The main malfunctions of the oil supply system on a chainsaw can be divided into two main types, these are general malfunctions inherent in all chainsaws and individual, which may vary depending on the type of pump and worm gear installed on a particular model. Let’s start sorting out the faults in order.

Working with a chainsaw if the chain is not lubricated is prohibited. This adversely affects the tire, the drive sprocket and the chain, and can also result in serious repair costs.

Signs of a malfunction of the lubrication system, checking its performance

  • The chain of the chainsaw is dry and has a pale shade without shine.
  • The chain stretches relatively quickly.
  • The tire is very hot and may even partially melt the paint.
  • Oil from the tank is practically not reduced.
  • Sharp chain cut efficiency

All these signs indicate that the lubrication process is abnormal. In order to check the oil supply by the lubrication system, it is necessary to remove the side tire of the chainsaw and start it. Next, you need to slightly increase the speed while observing the end of the oil line. If oil comes in, most likely its quantity is not enough for normal lubrication and you need to clean or replace the filter and, if possible, adjust the flow. In the case when it does not arrive, the problem is more serious and requires further diagnosis.

There is a way to check the oil supply without removing the tire. To do this, it is necessary to direct the end of the tire to the side, for example, of freshly sawn chocks from the cut side and maximize the speed, while you should try to keep the end of the tire at a distance of no more than 10 cm from the chocks. If oily stains begin to appear on its surface. then the oil is supplied.

Troubleshooting

Once it has been determined that no oil is being supplied, further diagnostics are only possible if the oil system is completely removed. Of course, filter replacement helps in some situations, but this is very rare.

Access to the oil pump of some models of saws is possible only after complete disassembly, respectively, having no skills in repairing gas tools, it is better to entrust the repair to professionals.

Most common malfunctions

  1. Breakage of an oil hose. It can sometimes be found during visual inspection. The problem is solved by replacing the defective part.
  2. Lack of thread on the shaft of the oil pump will help replace it.
  3. A defective thread on the pump drive gear is likewise solved by installing a new part.
  4. No corkscrew of the main shaft (relevant for some models of tools, for example, Homelite). You can fix it by installing a corkscrew that is suitable for the diameter of cloves instead of the native corkscrew, cutting it to the required length.
  5. Blockage in the highway. It can be removed by blowing with compressed air or mechanically, using a wire of suitable diameter.
  6. Clogged filter element.
  7. The Stihl MS 180, whose pump is not separable, often clogs. You can try to rinse in clean gasoline if it does not help replace it.
  8. In Chinese chainsaws (Gypsy), very often cuts the grooves on the main gear, through which the force from the sprocket is transmitted to it.

Stihl MS 180 individual lubrication system malfunction

Due to the fact that the Stihl MS 180 is one of the most common chainsaw models, I would like to dwell on one malfunction inherent only to it and describe a method for eliminating it without replacing parts.

Quite often on a Stihl MS 180 chainsaw, there is a depressurization of the oil line in the place where the oil pipe coming from the tank is installed in the saw body. The malfunction can be determined by the characteristic smudges on the bottom of the tool.

To eliminate the malfunction, it is necessary to remove the chainsaw handle, remove the hose from the bore hole, clean and degrease it. After all these manipulations, apply sealant to the hose seat and install in the chainsaw body.

You can learn more about troubleshooting and a complete diagnosis of the Stihl chainsaw lubrication system by watching the video, which shows step by step the process of disassembling and repairing the lubrication system.

Conclusion

In modern chainsaws, a reliable supply of lubricant for the chain is organized, in case of malfunctions of which, it is not worth operating the chainsaw in order to avoid further breakdowns. It is better to troubleshoot the lubrication system by contacting a service center or a specialist with repair experience, this ensures the quality of the final result.

Not oil arrives on the chain Chainsaws: Prerequisites and Solutions

When moving the chainsaw chains in the groove of the tire due to friction, a huge amount of heat is generated. If not oil arrives on the chain chainsaws, you need to suspend the work and take all measures to eliminate the malfunction of the lubrication system. The combination of huge loads and overheating of the headset is accompanied by its accelerated wear and premature failure.

  • Without exception, all chainsaws and their electronic counterparts are equipped with the same type of action systems, by means of which lubrication of the tire, the saw chain and its drive parts is realized.
  • A tank is included in the standard composition of this device, from which the chain oil is supplied to the pump inlet with a fixed or adjustable capacity.
  • Next, the working fluid in a metered amount enters the groove of the tire, in which the shanks of the saw chain are moderately distributed over the entire headset and the working surface of the crown of the drive sprocket.

Tires for product sets over 400 mm are equipped with a driven sprocket. Repeated bearing lubrication is done personally, after 6-8 hours of production.

Symptoms of a lubricant system malfunction

The right choice of consumable lubricant and the perfect operation of the system contribute to true lubrication, efficient cooling of the saw equipment and the full development of its resource.

There are several external signs that the chain on the chainsaw is not lubricated. First of all, it is:

  • constant oil level in the tank;
  • increased load on the engine;
  • accelerated wear of the cutting edges of the saw links;
  • the corresponding smell of overheated wood.

In the most ordinary variant, a prerequisite for oil starvation may be clogging of oil-conducting channels with sawdust. This defect is typical for economical headsets that do not have comfortable access to problem areas.
