Troubleshooting STIHL 180 chain saw oil pump

Your chain saw is designed to be operated according to the Instruction Manual so that it has a long service life and no malfunctions. All STIHL chain saw faults can be found and repaired by yourself. Let’s look at the main faults that can arise in the nodes and design of the device, and how to repair STIHL 180 chain saw with their own hands.

Plugging

If you’ve noticed that your STIHL chain saw is primed for spark plugs then the problem may be in the fuel system. The engine has to run on a mix of petrol and oil. Poor mixture reduces performance, overheats the cylinder and wears out the chain. Wet spark plugs on STIHL chain saws are often caused by an incorrectly mixed fuel. Lack of air in the mixture prevents proper combustion of the emulsion.

Using low-quality gasoline can lead to engine wear.

Plug greasing also causes the use of 4-stroke oil and piston wear. If this fault occurs, remove the fuel tank lid and adjust the fuel supply. The air intake needs to be repaired. Blow out the clogged filter with air or better replace it. How to clean the filters is described in your chain saw operator’s manual.

You can determine the quality of the mixture with the help of the insulator. If it shows a brown color, it means that the quality of mixture is normal. The white color or soot indicates a lean or overcharged mixture.

The spark plug can be the cause of the oiling. Failure of the spark formation is observed if the clearance is not set correctly. The spark plug contact distance is given in the repair manual. If you have no such data, you can set it to 0.7-1 mm.

If the gap is too small, the ignition efficiency of the mixture is reduced; if it is too large, the formation of the spark is interrupted. To stop the over-enrichment in the mixture, you can bleed the motor. To do this, remove the spark plug and turn the crankshaft a few times with the hand starter.

The chain is not lubricated

When repairing the chainsaw, you may notice that there is no oil on the chain. If the chain is not lubricating, there is a problem with the lubrication system. These faults can occur:

  • The chain is dry and light in color.
  • The chain is stretching too fast.
  • The bar is too hot and the paint on it has melted.
  • Oil in the tank does not run out.
  • Cutting is not as good as with a sharp chain.

This is a very good indication that lubrication has become intermittent. To check if there is oil in the lubrication system, remove the bar and operate the chain saw. Then increase revolutions and watch the oil line end point. If oil is flowing, it means there is not enough oil volume for proper lubrication. If there is no supply, the filter must be cleaned. Also the oil flow should be adjusted. If there are no malfunctions, further diagnosis and repair with your own hands is required. If it turns out that the substance is not fed, then the oil system is repaired.

Let’s consider the main faults and methods of their elimination:

  • Oil hose breakage. This can be seen during inspection. Change the hose if necessary.
  • If there is no thread on the oil pump shaft, replace it.
  • If there are defects in the thread, it must be replaced.
  • If the main shaft spindle is missing, a nail of the same diameter can be installed in its place.
  • The filter could be clogged. This is frequently the case with the STIHL MS 180. You can flush it with petrol. If this does not correct the problem, the filter should be changed.

STIHL 180 chain saws often have a leaking oil pipe. This is where the oil pipe from the tank goes into the tool housing. You can tell when there is oil leaking from the bottom of the saw.

To fix the problem, you need to remove the saw handle, pull out the hose. After that you need to clean the hose. Then apply sealant to it and place it in the tool body.

Does not start

If the chain saw does not start, it could be because of a fault in the ignition and starter assembly. If no abnormalities are found when measuring the clearance between the module and the flywheel, the spark plug should be checked. Remove it from the housing and check the play. If fuel is flowing into the combustion chamber and there is no ignition failure, then the carburetor is defective.

It is not revving

If the saw does not maintain idle speed then the following is probably wrong

To repair it yourself, you need to do the following:

  • Flush or replace the fuel hose.
  • Clean filter.
  • Check the quality of the oil and gasoline.
  • Check the operation of the carburetor and spark plugs.

STIHL chain saws work properly when serviced.

If the saw does not pick up speed, it could be caused by:

  • Faulty engine;
  • Cylinder wear;
  • Piston ring failure;
  • Spark plug failure;
  • Failure of the coil;
  • carburetor screws unbalanced.

If no defects are found after testing, then check the carburetor.

Partner 350 chainsaw oil. how to choose?

To extend the life of the engine and other working mechanisms of the garden tool, you need to use quality engine oil for the fuel mixture. When it burns in the cylinder, it should form as little ash as possible, which settles on the walls of the muffler and on the spark plug.

The engine oil you use must be able to dissolve quickly in your gasoline and be thoroughly cleaned of the foreign substances that tend to settle in the narrow channels of your Partner‘s carburetor.

Additionally, Partner 350 chain saw oil should have good lubricating and corrosion-resistant properties and be able to stand up to wear and tear.

STIHL and Husqvarna 2-stroke engine oils are the oil of choice for the fuel mix. They are good for lubricating a Partner hedge trimmer and do not produce ash on combustion.

Which Chain Oil for a Chainsaw is the Best to Buy?

If you are interested in chain oil for a chainsaw, we recommend that you buy this consumable according to certain criteria. First of all, the lubricating oil for your chain must fit your STIHL or Husqvarna chainsaw. Also, when choosing chain oils you should be guided by the following parameters:

  • Purpose. Chainsaw lubricants can be intended for the cutting segments and for the correct operation of the motor;
  • Composition. Special chainsaw head lubricant can be semi-synthetic, synthetic or mineral;
  • Manufacturer and power of the equipment.

If you choose the lubricants on the chainsaw for the care of the headset, we recommend buying two lubricant options at once. synthetic and semi-synthetic oil. These oil types have different viscosities and the ability to respond to ambient temperatures. For example, mineral oil for the chain can only be used in the summertime, because even in a slight cold such lubrication solidifies and can not penetrate into the small nodes and elements of the equipment.

Semi-synthetic and synthetic chain oil, which can be ordered together with the lawnmower disc in the store catalog, can be used at a temperature of 2530 degrees, ensuring proper and constant lubrication of the saw headset.

The feature of independent search and troubleshooting

Fully independent repair chain lubrication chainsaw, all things being equal, requires knowledge of the interaction of all elements of the system, the availability of tools and locksmith skills.

Many chainsaws can be repaired with partial or complete disassembly of components. It is better to use the capabilities and technical potential of service workshops for complicated repair jobs.

Parts with chopped threads, damaged spline connections or loose threads in the lubrication system of the popular STIHL 180 chain saws and other models of the same type must be replaced.

If there is no oil in the headset when the tank is primed, the cause is in the pump itself. Dismantling and disassembling the mechanism will help identify faulty parts and repair the problem by replacing them.

Possible causes of fuel failure

There are only 2 things that can cause a chain not to get oil. These include:

The main reason for breakage is air leakage. It can happen because the oil hose leaks while you are using the chainsaw. In this case, it is necessary to remove the hose from the hole. This should be done where it is connected to the crankcase. Then the hose is put on the sealant and set in the usual position. If this does not help, it is most likely that elasticity has been lost. For further operation of the chainsaw it is advisable to replace the hose.

The second reason. failure of the oil pump drive. In common parlance, this part is called a worm. When the actuator fails, the oil stops flowing to the chain. The oil pump actuator is a round plastic ring with grooves inside it. Continuous use of the chainsaw leads to wear of internal parts, which results in chipping of the metal hook inside the drive. After this failure, oil stops flowing to the chain.

You can fix the problem yourself or with the help of specialists.

Causes of reduced performance and system efficiency

There are several reasons why the chainsaw chain oil is not flowing in the right amount. Of the most typical failures, we can name:

  • clogging of the filter located in the oil tank;
  • Mechanical failure of one of the pump’s worm drive components;
  • In winter, the performance of the blower decreases due to filling the system with too thick oil.

What you have to know before you do the repair

The “golden rule” of self-repair. Use only original parts and spare parts. If you try to install the wrong elements, a different brand and configuration, this is a 100% guarantee of future breakage and failure of the electric saw. Before you fix the tool, build yourself the necessary base. You will need: 1. Original factory parts from the same manufacturer. 2. Pliers, wrenches 3. Electric tester, voltmeter. 4. Soldering iron. 5. Circular and oval files, mandrels and gauge for sharpening. 6. A chain sharpening machine (ideally, you can also sharpen by hand).

Price range and warranty repair shops

If you have a chain saw, it’s always a good idea to carry spare parts so you can make repairs on the spot if necessary. Amateurs should never try to repair a chain saw themselves. Improper repairs can cause more serious damage. There are many services available for repairs. try to go there. Time needed for repair. In good firms, minor repairs are carried out in only two or three days, but if the breakdown is serious, you will have to wait about a week. Always look for a warranty when selecting such a service. It should be on the parts themselves as well as the work!

(or in the vicinity of it).

Don’t be instantly frightened. Look through the reviews and maybe you’ve come across a really good shop, where you’ll get a quality repair at quite attractive and nice prices. Have a good job with your chainsaw and take care of yourself when working with it. Be safe and you will be fine.

Design and principle of operation of chainsaw oil pump

The groove on the shank ensures that the oil from the saw’s oil tank is captured and delivered to the hose that feeds it to the bar.

The plunger in brand-name examples of saws is made of one solid metal rod. But in the cheap kinds, usually the pinion is not only made by stamping, but also mounted on the plunger rod, which naturally affects the life of the part.

End honing has several types:

  • On the body there is a longitudinal groove for ½. 1/3 of plug diameter for oil catching;
  • The radial groove at the end provides the ability to adjust the plunger movement relative to the axis.

It is important when replacing the oil pump to pick up all the parts of this particular series of chainsaws for maximum alignment of all the protrusions and grooves with the body and the regulating eccentric.

The structure of the oil pump

The first thing that comes to mind for a chainsaw holder who has noticed malfunctions in the oil feed pump is where to look for this assembly? It is located where the power train is, on the same side, directly in the crankcase. This part is hidden behind the main sprocket. Its design is easier to disassemble based on the operating diagram of a particular model.

So if you need to find and repair a STIHL 180 chain saw oil pump, for example, check out the manual for this model. In general, of course, the principle of operation of the oil pump is the same, although on each model of the tool to look knot may look different.
