How to disassemble STIHL 180 full video

As an oil supply mechanism for chain lubrication, the STIHL MC 180 chainsaw uses a mechanical oil pump. What is catchy, the STIHL 180 oil pump is 100% made of iron parts and is practical and extremely reliable. Let’s take a closer look at how the oil supply system of the STIHL 180 chainsaw is organized.

The oil pump drive consists of 2 parts, this is a plastic gear with a worm gear and a wire lever that transfers the force from the sprocket-drum to the worm gear.

One of the main defects of an oil saw that allows accounting (software) is a defective thread on a plastic gear of an oil drive, therefore, with any ability, you need to keep under control its wear and thread quality.

The lever is aggressively attached to the gear and they are supplied as one piece. The tip of the wire arm has a suitable curvature for the best grip on the drive sprocket drum. The drum has a special slot for installing the drive.

The STIHL 180 oil pump is one hundred percent made of metal and has a non-collapsible design. The pump housing has an oil inlet and a groove-channel through which oil from the oil line enters the pump directly. The mechanism is installed in the body of the STIHL 180 chainsaw.

At the moment of an increase in engine speed, the drum. an asterisk begins to twist the worm gear by the wire lever, and it again forces the plunger of the oil pump to rotate, and as a result, the oil begins to be pumped through the oil channels to the tire of the chainsaw.

In the work of the accounting system, it perceives the specific role and oil line of the chainsaw, at the base of which there is an oil receiver. The oil receiver is additionally a filter. On the 2nd side of the oil hose, a rubber expansion is made, with the help of which the hose is installed in the body of the STIHL 180 chainsaw immediately behind the oil pump.

As everyone knows, in this world there is nothing endless and over the years what remains to be done by our client has to be repaired. So the oil system STIHL ms 180 is no exception, and has its own special malfunctions. Let’s take a closer look at them.

Signs of a malfunction of the lubrication accounting software complex, the following:

  • the chainsaw chain is completely dry and does not even shine;
  • oil does not leave the oil tank;
  • the chain is rapidly stretching and this situation occurs all the time;
  • the saw bar is pulled to the side during sawing;
  • the tire heats up and in the area of ​​the drive sprocket, paint melting is observed.

Diagnostics

Diagnostics should begin with an inspection and check of the oil receiver (filter) of the STIHL 180 saw. As a rule, if the filter is heavily soiled, the oil supply may stop.

In order to save money, you can try to clean a clogged filter by rinsing it thoroughly in gasoline.

Next, you need to remove the sprocket drum, and check the condition of the drive gear. The thread on it should be clearly defined, not licked and not have any other defects, also with the gear removed, it is necessary to check the wire lever. It must squeeze the gear tightly and not turn, otherwise, the gear is in place and does not transmit force to the pump, as a result of which the oil supply stops.

If all of the above methods to detect and eliminate malfunctions have not yielded results, extreme measures must be taken, i.e. dismantle the pump.

You should know the basic rules of the idle speed option:

1) check the air filter, if necessary, change it;

4) check the spark arresting grille, if necessary, change or clean it. Then there is an option to turn on the engine, and at the end to warm it up.

Repairing a STIHL MS 180 carburetor is a very difficult process. Note that when performing repairs, the risk of sharp configurations of the cylinder-piston group is virtually absent.

How to Change the Oil Pump of a STIHL Chainsaw

The second method is to remove the tire from the chainsaw and start it. With an increase in the number of revolutions of the motor, at the installation site of the tire shank, oil will flow from the oil channel, if this does not happen, you need to find the cause of the malfunction.

Diagnostics should start with the inspection and check of the oil receiver (filter) of the STIHL 180 saw. Normally, if the filter is very dirty, the oil supply may run out.

In order to save money, a clogged filter, there is an option to try to clean it by rinsing it well in gasoline.

Next, you need to remove the sprocket drum, and check the condition of the drive gear. The thread on its surface must become correctly expressed, not licked and not even have any other flaws, also with the gear removed, you need to check the wire lever. It must tightly squeeze the gear, not turn, otherwise, the gear is in the workplace does not transfer force to the pump, under the influence of which the oil supply stops.

If there is anything left to do for our client, the methods listed above to find and remove the malfunctions did not work, you need to use the last measures, that is, dismantle the pump.

The oil pump is installed on the right side of the bottom of the case, in the same place the oil line coming from the chainsaw tank fits to it. To remove the pump, you will first need to free the saw from the handle; for this purpose, the rear handle of the unit is unscrewed and the throttle control rod is disconnected. Next, you need to pull out the plugs of the shock absorbers of the handle and, if you have a strong slotted screwdriver, squeeze them out of their own seats on the handle.

Chainsaw “Calm 180”: malfunctions and repairs with your own hands

The popularity of this device is also determined by the acceptable price. But when using this tool, there may be some problems from time to time. After the expiration of the warranty period, you can repair yourself, because the services of the service center specialists are quite expensive.

Failures in the lubrication system of the chainsaw 180: causes and repairs

In the process of cutting wood, the cutting part of the tool is subjected to high loads. In order to reduce frictional forces and subsequent chain wear, the STIHL chainsaw is equipped with a lubrication system that gradually supplies oil to the bar. The rapid loss of cutting properties by the teeth and the absence of traces of lubricating fluid may indicate its leakage or clogging of the pipes.

First of all, when diagnosing the chain lubrication system for the ms 180 chainsaw, we pay attention to the oil supply hoses and their fixation points. Damaged connections cannot be repaired and must therefore be replaced. The oil channels can be cleaned with compressed air. For these purposes, we use a compressor or an ordinary car hand pump.

Due to its ease of operation and repair, the chainsaw of this model has gained wide recognition among professionals and amateurs in the field of woodworking.

How to remove and replace an asterisk

Chainsaw sprocket replacement is needed when:

  • jams the movement of the chain;
  • the drive sprocket is worn out.

To replace, you need to remove the chain saw sprocket. The sprocket teeth must not deviate from the required dimensions, otherwise the saw operation will be accompanied by vibration, which will lead to damage to the crankshaft and bearings. The lifespan of the sprocket is 2 times that of the chain. Use 2-3 chains until the cutting surface is abraded. After that, change the asterisk. It is located behind the clutch. Remove the clutch cover.

Remove the bar, chain, and clutch. But first you need to fix the crankshaft. Then the stripper is placed in the hole of the sleeve and turned clockwise. Remove the clutch. There is an asterisk behind it. Now it is being dismantled. If it is defective, it is replaced.

The main malfunctions of the chain saw “Stil 180”

The Calm 180 chainsaw, malfunctions and repairs that you can identify and repair yourself must be operated in accordance with the manufacturer’s instructions. For example, the start button should only be activated after the technician has checked the chain tension and has also verified that the respective tanks are filled with oil and fuel mixture. The chain saw should only be held securely in your hands after you can start working.

Chainsaw engine breakdown

During operation, parts of the cylinder-piston group of the saw fail due to friction forces, high temperatures and loads. If the tool does not reach full power at startup and stalls at idle speed, a possible problem could be damage to engine parts. To disassemble the power unit, it is necessary to unscrew 4 bolts and remove the cylinder. The owner is required to carefully inspect its internal work surface for the presence of chips, nicks and cracks.

Even the slightest damage to the “mirror” of the cylinder can negatively affect the compression of the chainsaw engine and its performance.

Cylinder-piston group of the STIHL MS180 chainsaw

When diagnosing an internal combustion engine, we also perform a visual inspection of the piston and compression rings. Made of aluminum alloy and cast iron, respectively, they are more exposed to abrasion loads than a steel cylinder. In case of breakage and excessive wear of the piston rings, it is necessary to replace them.

If, upon visual inspection, the ovality of the cylinder working surface is observed, it will need to be bored. To do this, we measure its diameter over a larger size, select the piston and perform the subsequent machining.

Expert advice

When repairing a carburetor, you must remember that this is a complex assembly, consisting of rings and many parts. This means that cleaning and repairs must be carried out with utmost care. If the tool stalls or does not start, the spark plugs must be checked in addition to the carburetor. If they are defective, they are rolled up and dried.

Additional fuel can be drained through a special opening. Malfunctions of the Calm 180 chainsaw and their elimination are partially described in the instructions. After reading the article, you can understand that the candles must be dried for at least half an hour, after which the candle can be installed in place by running the device.

Chainsaw engine runs intermittently

The reason for such a malfunction may be a breakdown of the cylinder-piston group, which is quite simple to repair with your own hands.

To remove the cylinder from the tank, four bolts must be unscrewed on its head. Then carefully check the piston, on which there should be no scoring, scratches, chips. If present, the piston will need to be replaced.

The optimal pressure in the combustion chamber is ensured by the piston and piston rings, which must sit tightly enough on the piston body. If the piston inserted into the cylinder during rocking has a free stroke, then this indicates its wear.

This defect can be eliminated by boring the cylinder and installing repair parts. However, the easiest way is to simply replace the entire CPG set.

All about the STIHL 180 oil pump

The STIHL MC 180 chainsaw uses a mechanical oil pump as an oil supply mechanism for chain lubrication. Remarkably, the STIHL 180 oil pump is completely made of metal parts and is practical and highly reliable. Let’s take a closer look at how the oil supply system of the STIHL 180 chainsaw is organized.

Diagnostics

Diagnostics should begin with an inspection and check of the oil receiver (filter) of the STIHL 180 saw. As a rule, if the filter is heavily soiled, the oil supply may stop.

In order to save money, you can try to clean a clogged filter by rinsing it thoroughly in gasoline.

Next, you need to remove the sprocket drum, and check the condition of the drive gear. The thread on it should be clearly defined, not licked and not have any other defects, also with the gear removed, it is necessary to check the wire lever. It must squeeze the gear tightly and not turn, otherwise, the gear is in place and does not transmit force to the pump, as a result of which the oil supply stops.

If all of the above methods to detect and eliminate malfunctions have not yielded results, extreme measures must be taken, i.e. dismantle the pump.

The reason for the appearance of oil leaks on the bottom of the chainsaw

The STIHL 180 chainsaw has a characteristic malfunction, which consists in insufficient sealing of the place where the oil hose is installed in the chainsaw body and the appearance of a leak in this place. To eliminate it, just remove the handle of the STIHL MS 180 saw, disconnect the hose itself, rinse and degrease the seat in the body and the hose end, then apply sealant and reinstall the hose. Such a simple operation will reliably eliminate the malfunction and the oil will stop leaking.

How to remove the pump

The oil pump is installed on the right side of the bottom of the housing, in the same place the oil line from the chainsaw tank is connected to it. To remove the pump, you will first need to free the saw from the handle, for this the rear handle of the unit is unscrewed and the throttle control rod is disconnected. At the next stage, you need to remove the plugs of the shock absorbers of the handle and, using a powerful slotted screwdriver, squeeze them out of their seats on the handle.

After the handle is removed, the body of the chainsaw is turned upside down. The hose coming from the oil tank to the pump will be visible immediately. It must be removed from the seat.

The pump itself is removed with an M5 screw and a wide washer. The screw length should be approximately 45-50 mm. A washer is put on the screw and it is screwed into the pump (the inside of the pump is threaded). Further, as the screw is screwed in, the stop from the washer will force the oil pump to rise along the thread. Thus, the pump is removed from its seat. Before starting work, we recommend that you read the article on how to disassemble the STIHL 180.

For a better understanding of the pump removal process, you can watch the video below. In the video, the SC master shows in detail how to remove the oil pump from a chainsaw, and also describes the main malfunctions of the supply system.

The STIHL 180 oil pump is a very high-quality and reliable part, therefore it is necessary to change it only as a last resort, when all other elements of the system have already been checked.

After the pump is removed, it must be cleaned and blown out. As a rule, the main breakdown of an oil pump is its blockage. By removing it, the pump can be reinstalled.

Replacing the pump is only required if it is not possible to remove the blockage.

Pump design, lubrication systems and principle of operation

The oil pump drive consists of two parts, it is a plastic worm gear and a wire lever that transfers the force from the drum sprocket to the worm gear.

One of the main malfunctions of the saw oil system is a defective thread on the plastic gear of the oil drive, therefore, whenever possible, it is necessary to control its wear and the quality of the thread.

The lever is rigidly attached to the gear and they are supplied as one piece. The tip of the wire arm has a characteristic curvature that is designed for better grip on the drive sprocket drum. The drum has a special slot for installing the drive.

The STIHL 180 oil pump is completely made of metal and has a non-collapsible design. The pump housing has an oil inlet and a groove-channel through which oil from the oil line enters the pump directly. The mechanism is installed in the body of the STIHL 180 chainsaw.

At the moment of increasing engine speed, the sprocket drum begins to rotate the worm gear by the wire lever, and it, in turn, causes the oil pump plunger to rotate, as a result of which the oil begins to pump through the oil channels to the chainsaw tire.

In the operation of the system, the oil line of the chainsaw is also directly involved, at the end of which there is an oil receiver. The oil receiver is additionally a filter. On the second side of the oil hose, a rubber expansion is made, with the help of which the hose is installed in the body of the STIHL 180 chainsaw immediately behind the oil pump.

Malfunctions of the pump and the system as a whole

As you know, there is nothing eternal in this world and over time everything has to be repaired. So the oil system STIHL ms 180 is no exception, and has its own specific malfunctions. Let’s consider them in more detail.

Signs of a malfunctioning lubrication system are as follows:

  • the chainsaw chain is completely dry and does not shine;
  • oil does not leave the oil tank;
  • the chain stretches quickly and this happens all the time;
  • the saw bar is pulled to the side during sawing;
  • the tire heats up and in the area of ​​the leading sprocket, paint melting is observed.

All these signs directly or indirectly indicate problems in the chainsaw chain lubrication system.

The first thing to do after you suspect that chain oil is not being supplied is to check the supply. This can be done in two ways. The first is described in detail in the instructions for the tool and consists in the fact that you need to start the chainsaw, add gas as much as possible and direct it towards any obstacle.

With a working lubrication system, oil will fly off the tip of the tire and a strip of oily drops will appear on the surface towards which the tire is directed. If there are any irregularities in the system, the surface will remain clean.

The second way is to remove the tire from the chainsaw and start it. With an increase in the engine speed, at the place where the tire shank is installed, oil will flow from the oil channel, if this does not happen, it is necessary to look for the cause of the malfunction.
