How to Put a 180 Stihl Clutch Washer Correctly

Stihl MS 180. A reliable and unpretentious tool, but sometimes requiring repair, like any equipment. In this article, we will consider how the Stihl ms 180 chainsaw is disassembled, which is necessary in the event of an overhaul of the engine.

Preparatory stage

Repair of any equipment should begin with the preparatory phase, and the Stihl 180 saw is no exception. At the preparatory stage, before dismantling the Stihl 180 chainsaw, it is necessary to remove the side cover, chain and tire from the chainsaw. Next, with the help of a compressor and a brush, you need to clean the chainsaw from dirt, sawdust, oil drips and other things.

Particular attention when cleaning the saw should be given to the place where the chain sprocket of the chainsaw is located, because this is the most polluted area.

In places of large accumulation of oil, you can rinse with clean gasoline.

Handle removal

Direct disassembly of the Stihl 180, begins with the removal of the handle, which is attached to the body of the chainsaw using three rubber shock absorbers. To remove, it is necessary to remove the plastic plugs from the inner cavity of the shock absorbers, and then using a powerful screwdriver, squeeze out the upper shock absorber first, then the one that is closer to the rear handle.

A gas trigger is installed in the rear of the handle, which is connected to the carburetor through a wire rod, in order to disconnect the rod from the gas trigger, two screws must be loosened and the handle disassembled.

When the handle remains on one shock absorber, it is necessary to unscrew the chainsaw body from the inside of the handle and breaking it to the side, remove the body from the last rubber band.

Starter Removal

At the next stage, the upper housing cover is removed and 4 starter mounting screws are untwisted, after which it is necessary to remove the oil tank and fuel barrel covers. The starter is removed quite simply and no problems should arise.

After removing the starter, the opened internal cavity of the chainsaw needs to be cleaned, because usually on the body under the starter there is a large number of compacted small sawdust.

Flywheel removal

The Stihl 180 chainsaw flywheel is twisted with great effort, so to remove it you will need a head with a metal knob. The nut holding the flywheel is unscrewed by 13.

To block the crankshaft from turning, you need to unscrew the candle and install the piston stopper through the spark plug hole, if it is not there, you can use the old string from the starter, with knots attached to it and immersed in the cylinder through the spark plug hole.

It is strictly forbidden to keep the flywheel from turning by installing a power screwdriver and other tools between its ribs and the body, with this method of locking from turning, the flywheel blades are not able to withstand loads and break off.

After the piston in the cylinder is blocked, you can unscrew the flywheel nut. The thread in the nut is normal, so you need to twist to the left side. After loosening the nut, it is not necessary to completely remove it, it is enough to unscrew it until its upper edge is equal to the tip of the shaft, after which a soft metal drift is installed on the nut and a sharp blow is made to it. Thus, the flywheel jumps off the shaft from a sharp impact and can be easily removed without the need for additional tools.

Dismantling the clutch and drive the oil pump

Before disassembling the clutch, it is necessary to dismantle the drive sprocket. To do this, carefully remove the lock washer from the grooves on the shaft and remove the sprocket and needle bearing.

High head 19, unscrew the clutch. The thread on it is left, so it is unscrewed towards the tire, and not the rear of the Stihl 180 saw.

Having unwound and removing the clutch, you need to immediately remove the reflecting plate and the pump oil drive, this is easy to do, because they are put on the shaft without any attachment.

Carburetor, silencer and ignition coil

To remove the carburetor, it is necessary to have a head for 8 and an extension cord, with which it is convenient to unscrew the nuts of the carburetor and air filter. Before dismantling the carburetor, it is necessary to disconnect the ignition wire and the choke rod from the engine control lever and remove the lever, only then the air filter and carburetor are removed.

The Stihl 180 muffler is fastened with two nuts, having unscrewed which you need to pull it towards you, it can easily be removed.

The coil is mounted on two screws, for removal you just need to unscrew them.

Removing and disassembling the engine

The engine is held by 4 screws installed on the bottom of the Stihl 180 chainsaw. To remove, you need to untwist them, then carefully remove the engine from the seat and the rubber pipe of the carburetor.

How to Put a 180 Stihl Clutch Washer Correctly

To disassemble the engine, 4 crankcase screws are untwisted, and it is removed, then you can remove the crankshaft assembly with oil seals, bearings and piston rings.

Removing bearings and oil seals usually does not require additional tools, but if the bearings were pressed onto the shaft with force, then a special puller will be needed for dismantling.

To remove the piston from the connecting rod, you will need to remove the retaining ring from the seat, using a thin screwdriver, then the piston pin is extruded from the opposite side, after which the piston is removed to the side.

How to remove the clutch on a chainsaw of any brand

One of the most important parts of any device model is the clutch. This mechanism requires constant monitoring of correct operation. Periodically, it must be removed for inspection and necessary repairs. How to remove the clutch on a chainsaw of any brand correctly and how it is arranged, we will understand below.

How is a chainsaw

All types of units are driven by a gasoline internal combustion engine. When assembling, single-cylinder engines are installed in which high-octane quality gasoline is refueled.

Instead of the gearbox, a single-stage gear is used, which makes the chain move. The structure of the unit due to its simplicity allows it to work flawlessly in any conditions.

The unit device consists of such parts:

  • Ice single cylinder;
  • Gas tank;
  • Carburetor
  • Crank mechanism;
  • Clutch;
  • Saw chain and sprocket driving it.

In addition, there are such components:

  • Purification system for the air supplied to the carburetor;
  • Ignition mechanism;
  • Exhaust silencing system;
  • Emergency shutdown system in emergency situations.

In the photo you can see a variety of models from manufacturers Stihl, Husqvarna, Partner, Goodluck.

How is the engine of the chainsaw

In devices released recently, a single-cylinder two-stroke carbureted engine is installed. It includes several mechanisms that work seamlessly. The main components of the engine:

  • Flywheel;
  • Coupling;
  • Incendiary module;
  • Muffler;
  • Mounting sleeve.

The engine installed in the saw operates at a frequency of 13.5 thousand revolutions / minute, and therefore it requires processing with high-quality oil. A high level of system cooling during operation is required. The engine of the unit is equipped with a cooling system that delivers air for cooling systems.

Chainsaw Clutch

The clutch of the wood processing device is centrifugal and is activated automatically when the degree of engine speed changes.

If the speed is small, then the elements of the mechanism are pressed against the shaft. So the rotational motion is not transmitted to the sprocket.

With increasing revolutions, the elements diverge and are pressed against the drum, thus causing the chain to rotate.

A characteristic property of this type of device is braking during chain deceleration. So it turns out to avoid some damage. But nevertheless, this system is subjected to a huge load, so it is necessary to systematically carry out preventive inspection and repair.

How to take off

The drive sprocket also serves as a drum. One of the main reasons for the breakdown of this block is the grinding of the sprocket teeth.

In the monolithic version of the drum, the chain can cut through the sprocket during operation. Such a mechanism requires replacement.

In the case when the drum has a removable crown, it must be removed and replaced during maintenance. After that, the drum can function further.

But if there is none of this nearby, the question arises. How to remove the clutch yourself? If you have the necessary set of tools, you can easily implement your plan.

Of course, there are some differences in the models of different companies, but the disassembly scheme remains unchanged:

  • First, the chain brake cover is removed by turning the lever. Slightly twist nuts to loosen chain tension. After loosening, you can completely unscrew the nuts and remove the cover;
  • The chain and the guide bar are disassembled, as well as the mechanism is cleaned of dirt;
  • The cylinder head candle is turned out and the piston is fixed. To do this, the crankshaft should be rotated until the outlet opens and then a piece of rope is placed in the cylinder to lock the piston. After completion of work, the rope is removed from the mechanism;
  • The nuts on the clutch are unscrewed with the special wrench from the kit. In this mechanism, they are made with left-hand thread, and this must be taken into account when dismantling. After that, the mechanism is disassembled, and all its parts are inspected for damage. Worn parts must be removed and replaced with new ones.

After repair and replacement of parts, it is necessary to assemble in the reverse order. The disassembly process is presented in more detail in the.

To independently repair such chainsaws as Stihl, Husqvarna, Partner, Goodluck, you need to know some features of the models. For example, on some varieties of saws, a washer is installed (between the cup of the drive sprocket and the engine). During assembly, it must be installed in its original place.

If the model has a special spring that transmits rotation to the pump drive, it is extremely important that it is correctly installed after repair. Otherwise, the device may be seriously damaged.

After preventive and repair work, it is necessary to check whether the mechanisms are working properly.

How to remove and replace an asterisk from a chainsaw?

Many owners of gasoline chainsaws after a device breakdown are concerned about how to remove the chainsaw sprocket.

When replacing an asterisk, all work must be carried out carefully and with care.

The design of the chainsaw device is a classic mechanism that is driven by an internal combustion engine. The design of the unit uses one of the simplest single-cylinder two-stroke carburetor engines that run on gasoline.

The simplicity of the engine device and the design of the chainsaw as a whole is the key to the trouble-free and reliable operation of the device in difficult operating conditions. The operation of a chainsaw does not require a large amount of knowledge and skills from the operator.

The only condition for a long and uninterrupted use of the device is the implementation of regular technical inspection and maintenance of the device. In the process of working with the device, it is required to regularly replace the wearing parts.

READ  What Lubricant To Use For The Screwdriver Gearbox

To reduce tool wear, the lubrication of the saw chain, its tension, the degree of wear of the chain and the degree of wear of the drive sprocket should be monitored.

Before repairing a chainsaw, you should study its design. To replace one of the main structural elements of the device. The drive sprocket. It is necessary to study the mechanism of the clutch of the unit.

Implement Clutch Design

Chainsaws are units that are equipped with leading sprockets, which are a single complex with a clutch basket.

The clutch engages automatically, depending on the number of engine revolutions.

A centrifugal clutch is installed on the units, which is activated automatically, depending on the number of engine revolutions.

The presence of freedom of movement leads to the fact that under the action of the springs, the elements are attracted to the center of the rotation shaft and do not transmit rotational motion to the sprocket drum.

With an increase in the engine’s revolutions, the centrifugal force exceeds the force of the springs, which leads to the displacement of elements with friction pads. These elements under the action of centrifugal force are pressed against the inner walls of the drum.

The main advantage of this type of clutch is that when jamming of the saw chain occurs, elements with friction pads slip, which protects the internal combustion engine from serious damage.

The main reasons for replacing the drive sprocket

The universal key is the main tool that will be required when replacing the sprocket.

The most common causes that force you to repair the tool associated with replacing the drive sprocket are:

  • Jamming of the chain due to the occurrence of defects during operation of the unit;
  • High sprocket wear as a result of long-term operation of the unit.

With the regular use of the device, there is increased wear of the sprocket as a result of increased loads on it during the sawing of wood. There are two ways to operate the device:

  • Use of one saw chain;
  • The use of several saw chains alternately.

When applying the first method of operation, the chain is operated until complete wear. This method has several disadvantages. The main one is the problem of wear control during intensive operation of the unit.

When using two or more chains in the process, it is possible to achieve uniform wear of the chains and sprockets, which allows to extend the period of operation of the device until repairs are carried out, consisting in replacing the sprocket.

In addition to the wear of the sprocket, one should not forget about the bearing, which is installed in the sprocket. This structural element works at any engine speed. When replacing sprockets, the bearing should be changed at the same time.

The coupling complete with an asterisk should be replaced in a timely manner.

The maximum depth of wear of the sprocket teeth should not exceed 0.5 mm. The sprocket’s service life is twice that of one chain, so two chains should be used during operation. After the life of the chains is reached, a simultaneous replacement of the chains and the drive sprocket should be carried out.

Clutch drum replacement algorithm

For uninterrupted use of a chainsaw, regular technical inspection is necessary.

When replacing the clutch drum, only a strictly defined type of structural element of the device should be used for installation. When replacing the drum, the bearings of the structural member should be changed at the same time.

To carry out repair work, you should purchase a special repair kit, which contains a drive sprocket and bearing.

After acquiring the repair kit, the materials and tools required for the repair should be prepared.

The main tools that will be required during the repair are as follows:

  • Universal key that comes with the chainsaw;
  • Piston stopper, can be made of plastic or metal;
  • Special tool for centrifugal gear or clutch drum.

The work procedure consists of several stages. Each stage has its own characteristics depending on the design features of the chainsaw, but the scheme and sequence of work is the same for any model of the unit.

At the first stage, the saw headset is dismantled, the guide bus cover is removed. After removing the cover, the guide bar and the saw chain are dismantled. Unscrewing the fastening nuts is carried out using a universal key, which is included in the delivery package of the unit.

After removing the saw chain and guide bar, the air filter is removed. Then, the spark plug is dismantled. In place of the dismantled spark plug, the engine piston stopper prepared in advance is installed.

All actions should be carried out clockwise.

After removing the clutch, an approach to the internal parts of the device opens, that is, after removing the clutch, you can remove the sprocket.

After removing the clutch drum, inspection and verification of the crown and sprocket is carried out, depending on its type.

Depending on the design of this unit, wear-out structural elements are replaced.

When carrying out repairs, special attention should be paid to the springs of the centrifugal mechanism and its cams. If wear is detected, replace them.

In case the components are not satisfactory, all structural elements are installed on the chainsaw in the reverse order. First of all, unscrew the piston stop and pull out the starter cord, after that the piston stop is put in place.

This complex sequence of operations makes it possible to clamp the centrifugal mechanism on the crankshaft of the unit. The clutch is put in place and clamped using the universal key included in the chainsaw kit.

Clamping with a key should be done counterclockwise.

The last stage of repair work is the installation of the remaining structural elements of the device.

When replacing an asterisk, all work must be carried out carefully and with care. All repairs must be carried out using special tools, otherwise the centrifugal mechanism or the saw chain may be damaged.

Removing and replacing clutch on a chainsaw. Review, instruction

Chainsaws, for various reasons, need to be repaired from time to time. Of course, you can contact a service workshop or an experienced mechanic. However, many problems can be fixed at home, having only a minimal set of skills and tools.

Answering the question of how to remove the clutch from a chainsaw, we note that this is not a difficult operation, if we strictly adhere to the disassembly technology.

Owners of the tool may encounter certain difficulties if the chainsaw has been in operation for a long time, and the clutch parts are attached to each other.

However, in this case, you can disassemble yourself.
