All about the Stihl 180 Oil Pump

As the oil supply mechanism for chain lubrication, the Stihl MC 180 chainsaw uses a mechanical oil pump. What is noteworthy, 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 Stihl 180 chainsaw oil supply system is organized.

Pump design, lubrication systems and principle of operation

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

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

The lever is rigidly fixed to the gear, and they are delivered as one part. The tip of the wire lever has a characteristic bend, which is designed for better traction with the drive drum-sprocket. A special slot is made on the drum for mounting the drive.

The Stihl 180 oil pump is completely made of metal and has a non-separable design. On the pump casing there is a receiving hole for oil and a groove-channel through which oil from the oil wire enters directly into the pump. The mechanism is installed in the body of the Stihl 180 chainsaw.

At the time of increasing engine speed, the drum. Sprocket starts to rotate the worm gear for the wire lever, and it, in turn, causes the plunger of the oil pump to rotate, as a result of which the oil begins to be pumped through the oil channels to the chainsaw tire.

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

Malfunctions of the pump and the system as a whole

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

Symptoms of a lubrication system are as follows:

Chainsaw chain is absolutely dry and does not shine;
Oil from the oil tank does not go away;
The chain stretches quickly and this happens all the time;
Takes away the saw tire when sawing, to the side;
The tire warms up and in the area of the leading sprocket, there is a fusion of paint.

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

The first thing to do after you suspect that chain oil is not flowing is to check its supply. There are two ways to do this. The first is described in detail in the instructions for the tool and consists in the fact that you need to start a chainsaw, add gas as much as possible and direct towards an obstacle.

With a good lubrication system, the 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 run it. When the engine speed increases, in 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.

Diagnostics

Diagnostics should begin by inspecting and checking the oil receiver (filter) of the Stihl 180 saw. As a rule, if the filter is very dirty, the oil supply may stop.

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

Next, you need to remove the drum sprocket, and check the condition of the pinion 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 should compress the gear tightly and not turn, otherwise, the gear stands still 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 applied, i.E., dismantle the pump.

How to remove the pump

The oil pump is installed on the right side of the bottom of the case, in the same place the oil pipe coming from the tank of the chainsaw approaches it. To remove the pump, you will first need to free the saw from the handle; for this, the back handle of the unit is untwisted 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 chainsaw body is turned upside down. The hose going from the oil tank to the pump will be visible immediately. It must be removed from the seat.

The pump itself is removed using a screw with an M5 thread 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 cause the oil pump to rise along the thread. Thus, the pump is removed from its seat. Before starting work, we recommend reading the article on how to disassemble the Stihl 180.

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

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

After the pump is removed, it must be cleaned and purged. As a rule, the main breakdown of an oil pump is its blockage. By removing it, you can install the pump in place.

Replacing the pump is only required if it is not possible to eliminate clogging.

The cause of oil smudges on the bottom of the chainsaw

The Stihl 180 chainsaw has a characteristic malfunction, which consists in insufficient sealing of the installation site of the oil hose in the chainsaw body and the appearance of a leak in this place. To eliminate it, it is enough to 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 cease to leak.

Conclusion

The Stihl 180 chainsaw oil pump is a reliable and unpretentious part, which is rarely enough to cause a lack of chain lubrication. Disassemble and change the pump, it is necessary only in extreme cases, when there is confidence that the reason is 100% in it. You can do this with your own hands, because this operation is quite simple.

Basic Stihl Chainsaw Failures and DIY Repair Instructions

Stihl chainsaw is a tool that is designed for harvesting wood, processing plants, creating landscape design and other household needs. If any parts break down or the device fails, you will need to repair the Stihl chainsaw.

Major malfunctions

A chainsaw should be used according to the operating instructions, then it will last a long time and will not fail. All possible malfunctions of the Stihl chainsaw can be identified and eliminated independently. Consider the main problems that may arise in the components and design of the device, and how to repair a Stihl 180 chainsaw with your own hands.

Fills the candle

If you notice that a candle is being poured on a Stihl chainsaw, then possibly a malfunction has occurred in the fuel system. The engine should run on a mixture of gasoline and oil. If the mixture is poor, then a decrease in power occurs, the cylinder overheats and the saw systems wear out. A wet candle on a Stihl chainsaw is due to a disproportion in the fuel mixture. The lack of air in the mixture prevents the proper combustion of the emulsion.

Using low-quality gasoline can cause engine wear.

The oiling of the spark also causes the use of oil for 4-stroke engines, piston wear. If such a malfunction occurs, remove the gas tank cap and adjust the fuel supply. The air intake should be brought in good condition. A clogged filter must be purged with air, but it is better to replace it. How filters can be cleaned is described in the chainsaw instruction manual.

It will be possible to determine the quality of the mixture using a candle insulator. If brown color appeared on it, then this means that the quality of the mixture is normal. White or soot indicates a poor or over-enriched mixture.

The cause of oiling is a candle. Interruptions in the formation of sparks are observed when the gap is set incorrectly. In the instructions for repair and operation of the apparatus, the distance between the contacts of the candle is given. If you do not have such data, then you can set 0.7-1 mm.

If the gap is less, then the efficiency of ignition of the mixture decreases, if more, then interruptions in the formation of a spark occur. To eliminate over-enrichment of the mixture, purge the motor. In this case, you need to remove the candle and turn the crankshaft several times with a manual starter.

The chain is not lubricated

When repairing a chainsaw, you will notice that oil does not get on the chain. If the chain is not lubricated, it means that the lubrication system has interrupted. There are such malfunctions:

The chain is dry, light in color.
The chain stretches too fast.
The tire is too hot and the paint has melted on it.
The oil does not decrease in the tank.
With a sharp chain, the saw began to cut worse.

Such signs indicate that there have been disruptions in the lubrication process. To check the oil supply to the lubrication unit, remove the tire and turn on the chainsaw. Then increase the speed and observe the end point of the oil line. If the oil goes, then its volume is not enough for proper lubrication. If there is no feed, clean the filter. The oil flow should also be adjusted. In the absence of malfunctions, further diagnostics and DIY repair are required. If it turns out that the substance is not supplied, the oil system is repaired.

Consider the main malfunctions and methods for their elimination:

Breakage of an oil hose. This can be seen during inspection. In this case, the hose must be replaced.
If there is no thread on the oil pump shaft, replace it.
If there are defects in the thread, then it must be replaced.
If there is no corkscrew of the main shaft, then you can install in its place a nail of the same diameter.
Filter clogging could occur. With the Stihl MS 180 saw, this happens often. You can rinse it with gasoline. If this does not solve the problem, replace the filter.

The Stihl 180 chainsaw often has an oil line depressurization. This happens where the oil line coming from the tank is inserted into the tool body. Breakage can be detected by smudges of oil at the bottom of the saw.

To fix the problem, remove the handle of the saw, pull out the hose. After that, clean the hose. Then apply sealant to it and put into the tool body.

Does not start

If the chainsaw does not start, then the cause may be a breakdown of the ignition unit and engine start. If there are no deviations when measuring the gap between the module and the flywheel, then check the spark plug. They pull it out of the shaft and measure the gap. If fuel enters the combustion chamber, and there is no breakdown in the ignition system, then the carburetor is faulty.

Does not develop momentum

If the saw does not support idle, then the following may have happened:

Clogged filter;
Violation of the ignition system;
The carburetor has deteriorated;
Deformed engine parts.

For self-repair, you need to perform the following actions:

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

When the Stihl chainsaws are repaired, they will work correctly.

If the saw is not gaining momentum, then this could lead to:

Faulty engine;
Cylinder wear;
Failure of piston rings;
Breakage of the spark plug;
Coil malfunction;
Imbalance of carburetor screws.

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

How to disassemble, repair and assemble a Stihl chainsaw

To repair the device, you must first disassemble it. It is required to remove the side cover, saw chain and tire. Then clean the tool, blow it off with a compressor and clean all the nodes with a brush. Then remove the handle. To do this, remove the plugs from the shock absorbers with a screwdriver. After that, the shock absorbers and the handle are removed.

Then they remove the starter. Remove the housing cover and unscrew the starter screws. Remove the item. Then they remove the flywheel by unscrewing the nut that holds it, unscrew the nut of the flywheel. Twist to the left. Remove the flywheel. Then the clutch, oil pump drive and carburetor are dismantled.

After that, remove and disassemble the motor. It rests on 4 screws on the bottom of the saw. It is necessary to untwist them and take out the motor. Then disassemble the engine itself. Unscrew the crankcase screws, remove it. Then the crankshaft, oil seals, bearings and piston rings are dismantled. At the end of the disassembly, repairs and troubleshooting are performed.

After repair, the tool will need to be assembled back. To do this, install the piston on the connecting rod. The arrow on it should look along the chain, and to the left of the piston will be the side of the crankshaft in which the flywheel is to be mounted. Put the piston in the cylinder. Install bearings, oil seals and circlip in the cylinder. Then degrease the crankcase fixation place and install it in its place. During assembly, the reverse dismantling sequence must be observed.

How to remove the clutch

Before unscrewing the clutch, remove the drive sprocket. Remove the lock washer and remove the sprocket and needle bearing. Unscrew the clutch. Remove the reflector plate and pump.

How to remove and replace the sprocket

Replacing the sprocket on a chainsaw is needed in cases where:

Jammed chain movement;
Wear on the drive sprocket.

To replace, remove the chainsaw sprocket. The teeth of the sprocket should not deviate from the required dimensions, otherwise the work of the saw will be accompanied by vibration, which will lead to damage to the crankshaft and bearings. The sprocket’s life is 2 times the working life of the chain. Use 2-3 chains before abrasion of their cutting surface. After that, change the asterisk. It is located behind the clutch. Remove the clutch assembly cover.

Remove the tire, chain and clutch. But first you need to fix the crankshaft. Then the puller is placed in the hole of the coupling and rotated clockwise. Remove the clutch. Behind it is an asterisk. Now they are dismantling it. If it is faulty, it is replaced.

Repair and replacement of the oil pump

Consider how to change the oil pump. If the element leaks, then the gasket between its two parts should be updated. If this part of the oil pump is not damaged, then it must be wiped and put in place. Now check the hose. There should be no cracks on it. If the hose is damaged, replace it. Then the compressor cleans the output channels.

Piston replacement

Consider how the diagnosis and replacement of the piston group. It is necessary to check the condition of the cylinder and the degree of wear of the piston. After dismantling the motor, the pan is unscrewed, the crankshaft with the piston is removed from the cylinder. Unscrew the stoppers of the piston pin. If the piston is defective, it must be replaced. The retaining rings are fixed with a slit down. Before installing the piston group in the cylinder, the piston is lubricated with oil. Before mounting the crankcase, degrease its surface and apply sealant.

How to set the ignition

It is necessary to set the ignition on the chainsaw. The ignition is adjusted as follows:

How to Replace a Stihl 180 Oil Pump

Turn out the candle and evaluate its appearance;
Specify the distance between the magnets and the coil (up to 0.2 mm);
Check spark.

Carburetor repair and tuning

The carburetor is adjusted on a warm engine. If the engine cannot be tuned, then the carburetor may become stuck in the mixture with excess gasoline. To remove the part, it is necessary to unscrew the fastening nuts, disconnect the ignition and traction from the engine control lever. Then they remove the lever. Then you can remove the filter and carburetor.

The silencer is fixed with two nuts. You need to untwist them and pull the muffler towards you. Then unscrew the screws of the coil and dismantle it. At the Stihl saw, the carburetor has 1 idle adjustment screw. If the idle speed is violated, then a carburetor repair is needed. This is a complex process, it is difficult to do it yourself. Contact a repair shop.

Starter Cord Replacement

Remove the side cover. Inspect the inside of the protective cover. If there is no damage, check the launch unit. Unscrew the starter bolt and remove the spring. Diagnose a pulley with a cord. If the rope is intact, then each launch of the trigger mechanism is checked:

The starter cord is made of synthetics and gradually wears out. If it is damaged, has cracks or tears, then you need to replace it.

Stihl 180 chainsaw: malfunctions and DIY repair

The popularity of this unit is also due to an affordable price. But when using this tool, some problems may arise from time to time. After the warranty period, you can do the repair yourself, because the services of specialists of a service center are quite expensive.

Main malfunctions of the Stihl 180 chainsaw

The Stihl 180 chainsaw, the malfunctions and repairs of which you can identify and carry out yourself, must be operated in accordance with the manufacturer’s instructions. The start button, for example, should be turned on only after the master checks the chain tension and also makes sure that the corresponding tanks are filled with oil and fuel mixture. A chainsaw should be securely locked in your hands, only after you can start work.

Leakage

But if you notice that oil is leaking for the chain, then the cause of the malfunction may be a violation of the tightness of the joints of the hose of the oil tank and the oil pump. In order to fix the problem, you have to disassemble the tool. If the hose is damaged, it is recommended to replace it. Sometimes it is sealed with a special composition. The surface should first be degreased and washed. Sometimes the oil filter fails, in some cases it becomes clogged. Oil may also leak. In this case, the filter is checked, cleaned or replaced with a new one.

Refusal of work

The Stihl 180 chainsaw, the malfunctions and repairs of which you can identify and carry out with your own hands, sometimes simply does not start. Such a problem can occur completely by accident. First of all, the consumer needs to open and close the gas tank cap. Ventilation of the combustion chamber should be carried out in the next step.

It is recommended to remove the candles and dry them well. In some cases, this is enough for the tool to wound up and begin to work properly. If the problem remains, then the reason is different. Breather affects fuel supply. If it becomes clogged, a vacuum occurs in the fuel tank, which entails a refusal to work. The breather can be repaired very simply. To do this, it is cleaned with a needle.

Additional Waiver Recommendations

If you purchased a Stihl 180 chainsaw, you can find and carry out the malfunctions and repairs of this tool yourself. Sometimes the equipment refuses to work for the reason that the cylinder fails. If there are bumps and chips on this node, then the reason is precisely in it. If you encounter a problem when the instrument does not start, can withstand power for a short time or stalls after turning on, then the muffler can cause damage. During operation, it is sometimes clogged with deposits that occur during exhaust emissions.

The saw sometimes does not start well, which leads to malfunctions of the starter. In order to identify a problem, it is necessary to remove the cover and a special screen from the carburetor, which is located behind the drum of the tool. If the contact wire is disconnected from the starter, then it is fixed with a blowtorch. Sometimes the problem is oil leakage. In this case, the starter must be wiped with a rag.

The engine is intermittently

You can start to troubleshoot the Stihl 180 chainsaw yourself if the warranty period has expired. Sometimes the engine works intermittently, which can be caused by the failure of the cylinder piston group. You can repair it yourself. To remove the cylinder from the tank on its head, it is necessary to unscrew the bolts. The master should check the piston, it should not be chipped, scratched or scratched. If they could be found, then the piston must be replaced.

Piston rings and piston provide optimum pressure in the combustion chamber. The rings must be fitted tightly onto the piston body. If the piston inserted into the cylinder has free play when rocking, then this indicates its wear. To fix the problem, it is necessary to bore the cylinder and install repair parts. But the easiest way would be to replace the CPG kit.

Carburetor malfunctions

If you purchased a Stihl 180 chainsaw, you can find and carry out the malfunctions and carburetor repairs yourself. If the tool ceases to start, begins to stall and is not able to maintain power, and also does not maintain idle speed, then the carburetor may cause breakdowns. During operation, it often becomes clogged with dirt, dust or sawdust. You can fix the problem by cleaning it.

Stihl 180 chainsaw carburetor malfunctions are resolved after preparing some tools, among them:

Brush;
Head on 8;
Crosshead screwdriver;
Petrol.

Brush can clean dust and dirt. Then remove the cover and filter. Two nuts of the air filter are unscrewed, which will remove the air intake housing. Now you can see the carburetor. By lowering the shutter down, it is necessary to remove the accelerator lever.

Considering the main malfunctions of the Stihl 180 chainsaw, you should know that you should not forget about the fuel filter. They remove it and purge the fuel hose. Now you can collect everything in the reverse order. If, after assembling the carburetor, the instrument still does not start well and the muffler produces smoke, then the spring under the needle lever has been lost. Due to its absence, the needle does not block the fuel supply. As a result, the candle is filled with gasoline. To resolve this problem, you must find the spring and install it in place.

Specialist advice

When repairing a carburetor, you should remember that it is a complex unit consisting of rings and many parts. This indicates that cleaning and repair must be carried out with particular care. If the tool stalls or does not start, then, in addition to the carburetor, it is necessary to check the spark plugs. If they are faulty, they are twisted and dried.

Excess fuel can be drained through a special hole. Stihl 180 chainsaw malfunctions and their remedies are described in part in the instructions. After reading the article, you can understand that candles should be dried for at least half an hour; after this time, the candle can be put in place by starting the unit.

Conclusion

Sometimes the cause of the malfunction is poor contact between the high-voltage wire and the end of the plug. If the work of the candle does not like the master, it is changed to a new one. Before repair, it is necessary to remember that the tire, chain, as well as anti-vibration elements wear out much faster than other parts. Therefore, for uninterrupted operation, it is necessary to keep the listed parts in the arsenal.

The reasons for this behavior of the tool are the malfunctions of the chainsaw carburetor. This is expressed in pollution by dust particles, sawdust. Such a breakdown can be fixed on its own without problems.

Carburetor cleaning is carried out using:

A small amount of gasoline;
Phillips screwdriver
Brushes;
Heads, size 8.

The sequence of steps when performing repairs:

To begin repairing the carburetor, they begin by cleaning them of dirt and dusty particles, fine wood. To do this, use a brush. When the surface is completely free of debris, the repairman removes the cover, and then the filter.
The air collector is released after unscrewing the mountings of the air filter. Now the user gets access to the accelerator and rods. The accelerator lever is removed immediately, as the shutter is lowered by pressing the finger down.
From the seat, the carburetor moves back after the suction lever is removed and closed. Then the wire is removed and stretched out to stop the engine. A plastic lever is being shot, which is the place where the wire is attached.
He is raised on the left. As a result, the carburetor is released, which makes it possible to pull it out and clean it. For these purposes, the use of a compressor is convenient. In his absence, the parts are washed in clean gasoline.

A spring shuts off the fuel supply. In its absence, spontaneous “overflow” of fuel into the candle occurs. It is important to ensure that the spring is installed in its place, and make sure that the candle is working.

If the candle is poured with gasoline, then it should be dried. To do this, the part is twisted, merged, the excess fuel that has got inside, through the existing hole. The candle dries for more than half an hour. Then it is put into place, and the chainsaw is brought into working condition.

Insufficient contact between the high-voltage wire and the end of the plug can also be one of the causes of tool breakage. Stihl chainsaw parts can be repaired by replacing problematic parts.

Particular attention to the oil pump

The oil supply can be interrupted for various reasons. The most common malfunction of the oil pump. You can verify this by the condition of the chain lubrication.

If the oil supply to the circuit is interrupted, it becomes dry or excessively wet. These are signs of poor performance of the oil pump.

To eliminate the problem, the oil hose is inspected. The connection between the hose and the oil pump and tank is examined for leaks.

Problems arise such as the result of mechanical damage to parts of the oil system. To get to the problem area, this unit is disassembled.

If the repairman is convinced that the hose is damaged, replace it. However, depending on the degree of damage, it is possible to seal with special compounds.

Before sealing begins, the surface is washed and degreased. By repairing stihl ms 180 on its own, the consumer has the opportunity to radically save.

Identify problems in starting up the unit

There may be a problem in which the Stihl 180 does not start. It is usually associated with a broken starter. Actually, the unit does not start after tensioning the cord.

The reasons for the failure to start the starter can be:

Failure of the spring.
Cracked or broken pulley.
A rush of rope to run.

Before you find out the cause of the breakdown, and begin repairing the starter of the chainsaw, the chainsaw body is removed. To do this, unscrew the screws that hold the cover with the starter.

In this case, screwdrivers or a special tool are used. A visual inspection of the starter reveals the reasons why the tool did not start.

Damage to the pulley with cracks and tears is reflected in the performance of the tool. Detection of mechanical malfunctions or defects at the attachment point of the soft spring.

The attachment point, as well as the tip of the spring inserted into it, is vulnerable. If faults or damage to individual parts of the starter are detected, they are replaced with new ones.

Dismantling and maintenance of the piston system of the Stihl 180 chainsaw.

The unit can be repaired qualitatively with full compliance of the details with the brand of the chainsaw. The same spare parts replacement scheme also applies to saws during DIY repair.
