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.

Stihl 180 How to Change a Starter

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.

Stihl 180 How to Change a Starter

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.

Stihl 180 How to Change a Starter

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.

Stihl 180 How to Change a Starter

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.

Stihl 180 How to Change a Starter

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 video below. In the video, 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.

Stihl 180 How to Change a Starter

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.

Stihl 180 How to Change a Starter

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:

  1. The chain is dry, light in color.
  2. The chain stretches too fast.
  3. The tire is too hot and the paint has melted on it.
  4. The oil does not decrease in the tank.
  5. 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.

Stihl 180 How to Change a Starter

Consider the main malfunctions and methods for their elimination:

  1. Breakage of an oil hose. This can be seen during inspection. In this case, the hose must be replaced.
  2. If there is no thread on the oil pump shaft, replace it.
  3. If there are defects in the thread, then it must be replaced.
  4. If there is no corkscrew of the main shaft, then you can install in its place a nail of the same diameter.
  5. 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.

Stihl 180 How to Change a Starter

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:

  1. Flush or replace the fuel hose.
  2. Clean the filter.
  3. Check the quality of gasoline and oil.
  4. 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.
