Features of saw chains

The working mechanism of the saw is a chain. Dismantling the Stihl 180 chainsaw part 1. The manufacture of saw chains is carried out according to a special technology:

The cutting element is made of high carbon steel, and the use of chromium plating or applying a victorious layer to the cutter. Dismantling a Stihl 180 chainsaw part 1. The more complicated the manufacturing technology, the higher the cost of the chain.
The hinge holes are ground to reduce friction and extend service life.
Rivets are used only hardened by a special technology.
Marks are applied to the teeth, by which it is possible to determine wear and perform uniform sharpening.
After connecting the links in a chain, the product is subjected to stretching to ensure dimensional stability during operation.

A well-thought-out system of automatic chain lubrication increases the service life. New saws should be selected according to the characteristics specified in the operating instructions Stihl chainsaws 180.

You need to know chains with winning surfacing are 3-5 times more expensive than usual, but sharpen them with your own hands when repairing chainsaws Stihl 180 is impossible. Employees of the Ministry of Emergencies use this tool more often.

For a long maintenance-free period, use the oil recommended by the tool manufacturer. A special mineral composition is used to prevent chain grinding. It is not permissible to use oil intended for addition to Stihl gasoline for saws.

It is often asked whether longitudinal cuts can be made with a Stihl 180 saw. The power of the saw allows you to work on cutting wood only across the fibers.

In this we will show you how to replace the piston group on a chainsaw Stihl MS180, crankshaft oil seals.

Stihl 180 chainsaw malfunctions

It either sucks in air somewhere, or something is clogged.

The main ways to troubleshoot STIHL MS 180 chainsaws are to disassemble, rinse and blow out the carburetor, change the fuel filter in the tank, check the fuel hoses for cracking (they can suck in air).There is only one adjustment screw on the carburetor. Idle speed (it happens, turned it, and the chainsaw again worked).The connection of the carburetor with the cylinder, in terms of air intake, is reliable. There is a plastic ring (no gaskets are needed).

Stihl 250 chainsaw malfunction (chainsaw carburetor malfunction):

Immediately after the start-up, the chainsaw runs at high speeds, and if you press the gas, instead of starting to accelerate, it “chokes” and even stalls. Or it starts poorly, does not gain momentum and stalls (this malfunction of the chainsaw also applies to other expensive chainsaws with an accelerator pump in the carburetor).

Cause of chainsaw malfunction: Deterioration of a rubber cuff on a piston of the accelerating pump in the carburetor (fuel accelerator). This leads to air suction by the accelerator pump and the main jet delivers a lean air-fuel mixture (little gasoline in the mixture) into the diffuser and the chainsaw first runs at high speeds, and then “chokes” and stalls. This happens after 2-3 years of operation and usually happens in the hot summer months.

Chainsaw carburetor troubleshooting

Remove the carburetor from the chainsaw. Remove the fuel pump cover with the diaphragm by unscrewing one screw in the center of the cover. Then turn the carburetor to yourself with a throttle, on the side where there are two holes, a pin is visible in one, here under it there is an accelerator pump. Remove the retaining ring from the outside of the pin and detach the air spring of the air damper. Unscrew the screw in the center of the throttle, remember how the throttle is (to put it later) and remove the throttle. Finger plug the hole with the pin (the accelerator is spring-loaded and if you remove the throttle axis and do not close the hole, the accelerator will pop out), then rotate the throttle axis and remove it. Shake the accelerator (piston) with the spring out of the hole. On the piston there is a rubber cuff (ring). Its wear is the cause of the malfunction of the chainsaw. It is necessary to replace the piston with a rubber cuff and a spring (they are sold as a repair kit). Or you can take out a worn piston with a spring and plug the hole by pushing the rubber plug there (the chainsaw will be without an accelerator pump, i.E. It will accelerate not in 3 seconds, but in 4 seconds, but it will work well since there will be no suction air carburetor).

Dismantling and assembling the Stihl 180 chainsaw.

Assembly after troubleshooting a chainsaw (after troubleshooting a carburetor chainsaw) is in the reverse order of disassembly. When assembling the throttle valve, before tightening the screw, the throttle valve itself must be correctly positioned so that it does not jam, and the thread of the screw attaching the throttle valve to the axis should be degreased and greased with a special thread sealant (sold in small tubes, red, liquid) or flattened with pliers, because if this bolt is removed during operation, it directly enters the cylinder) and repair or replacement of the piston cannot be avoided). So we examined the elimination of this malfunction of the chainsaw.

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 lock 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 cord from the starter, with the components 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 the drift of soft metal 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.

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.

Stihl 180 chainsaw assembly

To assemble the stihl ms 180 saw back is quite simple, the main thing is to adhere to the following algorithm:

Install the piston on the connecting rod, the arrow on the piston should look along the Stihl 180 chainsaw, and the side of the crankshaft, which is used to install the flywheel, should be located on the left hand of the piston;
Carefully insert the piston back into the cylinder, the place for mounting the coil should be on the side where the flywheel is mounted on the crankshaft;
Install bearings, seals, circlip on the shaft and lower everything in the assembly into the seat in the cylinder;
Then degrease the crankcase installation location and the crankcase itself, then grease with sealant and tighten the 4 fixing screws in place;

To assemble a Stihl 180 saw after the moment the engine is assembled, the reverse disassembly sequence must be observed. It is important to take the process carefully and remember to install traction on the carburetor, and connect the ignition wire.

Below you can see the Stihl 180 disassembly in the, it is made for inexperienced users, it shows in detail the whole process.

Dismantling the Stihl 180 chainsaw and assembling it, with some experience, is quite simple, the main thing is to thoroughly clean the saw before work and not rush. In order for small parts not to get lost, you need to use containers in which, in the process, it is worthwhile to lay out spare parts.
