Repair of Shtil 180 chainsaw: faults and their elimination

Is it possible to repair a saw with your own hands?

This is the very first question that arises before the owner of a Shtil 180 chainsaw, which for some reason has stopped functioning normally. There is no clear answer to this question. It would be correct to say: it is possible, but is it necessary?

Repairing a chainsaw in a service center is of course more expensive than trying to fix problems yourself, but by using the services of specialists, you receive guarantees and confidence that the chainsaw will be properly configured and adjusted. In general, the choice is yours.

Another small nuance regarding the choice to repair it yourself or not is that in order to diagnose a chainsaw and its further disassembly and repair, you need to have some specific tools and certain knowledge of the design of the saw. Otherwise, you will not be able to even unscrew and remove the flywheel without damaging it.

When carrying out independent saw repairs, the aluminum fan blades located on the flywheel very often break off. This happens because during disassembly they do not use a special crankshaft stopper, but try to fix it by installing a screwdriver between the saw body and the flywheel blades, which leads to dire consequences. The flywheel nut has a serious tightening torque, and the blades are fragile and cannot withstand such force.

Preventing problems

At some point, problems with the starter appear on any trimmer

– Stihl FS 55, “MTD 790” or another brand.
It is possible to delay the occurrence of such a malfunction, but this requires careful handling of the equipment. Namely, you should not make very sharp jerks, as this will lead to the cord breaking or the spring flying out. It is not recommended to subject the lawn mower to impacts or other physical impacts. If the starter housing breaks and the cord breaks, it can wrap around the engine flywheel.
This will lead to a torn pulley and a burst spring. So, having found that the starter mechanism on a lawn mower is broken, you should not immediately rush to seek help from specialists. Knowing how to fix a malfunction and/or replace a part, repair work can be performed without the help of others. This does not require any specific tool. At first, the procedure may seem complicated and painful, but countless websites on the Internet dedicated to repairing the starter will help solve the problem very quickly and simply.

Recoil starter

for a lawn mower or gasoline trimmer - a mechanical unit, which includes a pulley mounted on a ratchet. A rope is wound around the pulley in the initial position. When starting, it stretches outward. The pulley is spring-loaded - as soon as you let go of the end of the rope, it will rewind back. A flat strip rolled into a ring is used as a spring. She recalls the spring in a huge mechanical watch that winds once a day. The starter itself is often located at the rear rather than closer to the front end of the mower or trimmer. In order to correctly carry out all the manipulations with the starter for a lawn mower, you should know the features of the device and installation.

Repair tools Shtil 180

To carry out a relatively high-quality repair of the Shtil MS 180 chainsaw yourself, you will need to have:

• air compressor (for cleaning the chainsaw and blowing out the main components and assemblies);
• a vacuum gauge is necessary to check the tightness of the crankcase and carburetor, as well as to identify defective seals;

• piston stopper to limit the stroke of the crankshaft;

• electronic tachometer in order to correctly adjust the chainsaw carburetor;
• T-key STIHL Torx 27 or equivalent;

• puller for crankshaft bearings.

Only if you have these tools, do-it-yourself repair of a Shtil 180 chainsaw can be done with sufficient quality.

Common breakdowns Shtil 180

Common malfunctions on a calm chainsaw include:

• Broken starter cord;
• Worn drive sprocket;
• Leaks in the oil supply system for chain lubrication;
• Worn oil pump worm gear;
• Air leakage through the seals into the engine crankcase;
• No spark at the spark plug;
• Lack of fuel supply in case of malfunctions in the carburetor (we will not dwell on them, since repairing and adjusting the carburetor of a chainsaw is a fairly broad issue and will be discussed in a separate article);
• Breaking off the eye of the seat under the engine control lever.

Now let's look at the faults in more detail and start with repairing the oil pump.

Chain brake, clutch, lubrication system

The reason for the failure of the quiet 180 may also be a malfunction of the brake circuit. Most often, the space under the transmission cover becomes clogged or the brake band wears out. If clogged, remove the cap and thoroughly clean the inside. Repair If the brake band wears out, it must be replaced.

How to replace the starter cord on a STIHL chainsaw yourself

Often there is a visually visible oil leak in the chain drive, which leads to improper operation of the chain drive. To fix the problem, you need to check the quality of the connection between the oil pump and the pipe, check them for cracks. If cracks are found, parts must be replaced or sealed. If there is not enough oil in the chain, then you need to clean the lubrication channels, which happens quite often.

READ STIHL carburetor adjustment saw

If the chainsaw works almost constantly on the chainsaw, the engine is sometimes unstable, then you should look for a fault in the clutch. It could be a break spring and a piece from the clutch cam could also break off. Fix the problem by replacing this assembly.

When operating a chainsaw, parts wear unevenly. To maintain the device, worn parts such as the chain be replaced tires and others. In this case, the Chainsaw 180 will work for a long time.

The STIHL MS 180 is a fairly reliable saw, but if it is used incorrectly or if low-quality lubricants are used otherwise due to operator negligence, defects may occur. When repairing a saw at home, you need to have certain knowledge and a special tool, in the absence of which repairs will not be possible. It should be noted that chainsaw is a technically complex tool and its service is best carried out in a car service center.

Oil supply system repair

If there is no oil supply to lubricate the chain, it is necessary to diagnose the entire system and determine the reason why the oil is not supplied. There may be several main reasons:

1. Clogged oil filter or oil system;
2. Missing thread on the oil pump worm gear;
3. Blockage or malfunction of the pump itself;
4. Depressurization of the oil system (there will be oil leaks on the bottom of the chainsaw).

To check the threads on the worm drive of the oil pump, you will need to remove the chainsaw drive sprocket and unscrew the clutch. To do this, the spark plug is unscrewed and a piston stopper is installed in its place, thereby ensuring reliable fixation of the tool’s crankshaft from turning.

Next, remove the cover from the side of the bar of the Shtil 180 chainsaw, and using a screwdriver, remove the retaining ring holding the drive sprocket, after which the sprocket itself is removed.

In this way, the sprocket of the Shtil 180 chainsaw is also replaced if necessary.

The clutch is untwisted using a 19mm socket and a wrench. It is necessary to unscrew the clutch clockwise, since the thread is left-handed. There is a reflective plate behind the clutch, this also needs to be removed. The next part is the worm drive of the oil pump. Having examined and discovered the absence of a plastic thread, you can safely throw out the part and install a new one in its place, since it is impossible to restore it. Assembling the Shtil 180 chainsaw is carried out in the reverse order.

If the gear is in normal condition, disassembling the saw continues; for this, the corkscrews are removed from the shock absorbers, the rear handle is untwisted and the throttle control rod is disconnected, after which the handle block is removed from the shock absorbers using a powerful slotted screwdriver.

It is necessary to remove the handles to provide access to the bottom where the oil pump is installed.

At the next stage, the oil hose coming from the oil tank is removed from its seat on the body and the line is checked for blockages by supplying air through the oil hose into the oil tank body. If a blockage is detected, it must be cleaned; if this is not possible, the faulty hose must be replaced.

Next, the oil pump is removed from the body of the Shtil 180 chainsaw and washed in gasoline.

As a rule, calm oil pumps rarely become unusable and require replacement. Basically, the reason for the lack of oil supply is a blockage, so by washing and checking the pump gear for turning, you can be sure that after reassembling the Stihl 180 chainsaw, problems with oil supply will disappear.

After repair, we assemble the Stihl 180 chainsaw in the reverse order. An important point is to seal the oil hose at the installation site, into the seat on the housing. It is necessary to rinse the hose and the hole for its installation with gasoline, then blow with compressed air until completely dry and coat it with sealing oil-resistant sealant, and then install it in place.

Do-it-yourself trimmer starter repair

Repairing the starter of a gasoline trimmer may be required at the most inopportune moment. With all this, the problem can be solved using 2 methods: change the broken part or change the entire assembly. The latter option will cost more. To repair a device with your own hands, the only tool you will almost always need is a screwdriver with a suitable tip. Repair work will not take much time and does not require special knowledge. It is enough to know the device, the operating mechanism, aspects of assembling and disassembling the starter on a trimmer in order to achieve a suitable good result.

Other faults

From time to time, after repairs have been carried out, the spring flies off as before. There are 2 solutions to fix this problem:

• To prevent the coil of the spring from jumping out of the groove, it is necessary to insert a small piece of iron plate between the bend and the wall of the landing site. This will ensure a tighter fit of the spring.
• A homemade fastening also helps to hold the spring in the groove. It is necessary to drill holes in the coil on each side of the groove, place a spring twist in them and secure it with a piece of wire. These steps should be performed so that the wire does not touch the starter cover and does not slow down the movement of the pulley.

Spring tension

After installing the spring, it should be tensioned. To do this, do the following:

• remove the handle from the starter cord;
• then the rope is inserted into the spool groove;
• create tension on the spring by rotating the coil in the opposite direction to the clockwise direction (winding);
• make the required number of revolutions indicated in the instruction manual for the trimmer model used and corresponding to the length of the cord used;
• at the very end, the rope is threaded into the hole created for this purpose, located in the starter cover;
• put the handle in place, fixing it with a knot.

If after repair the spring continues to fly off, you can get rid of it using the following methods:

• squeeze a suitable piece of plate into the groove at the location of the spring hook;
• Drill holes on both sides of the groove in the coil into which to insert the spring hook and secure it with a wire.

The control key of the Stihl 180 chainsaw is broken - how to fix it

A frequent breakdown of the Shtil chainsaw, which occurs due to the operator’s fault, is a malfunction in the operation of the engine control mechanism. More precisely, when the seat for the control lever breaks off due to its design features, solving this problem will require replacing the saw body, which is quite difficult to do on your own. Let's look at the do-it-yourself repair algorithm that involves replacing the chainsaw body:

• The body is freed from the handle block;
• The starter is removed; to do this, remove the caps from the fuel and oil tanks and unscrew the starter mounting screws;
• Next, a piston stopper is installed into the cylinder through the spark plug hole, the flywheel is untwisted and removed from the engine shaft;
• The drive sprocket is removed and the clutch is released;
• Unscrew two 8 mm nuts holding the air filter housing and carburetor, and remove the modules from their seats;
• At the next stage, the 4 screws holding the engine to the body are unscrewed. Special bushings are mounted into the body of the Shtil 180 chainsaw at the location where the engine mounting screws are installed, which can fall out on their own and get lost.
• The last point is to remove the oil pump, carburetor rubber elbow and fuel and oil tanks.

The parts must be installed in the new housing in the reverse order. In parallel with eliminating the main malfunction, you can check the rubber elbow of the carburetor; a part that has exhausted its service life and has lost its elasticity must be replaced.

Replacing oil seals

How to repair a Shtil 180 chainsaw if the seals need to be replaced? It is necessary to disassemble the engine, which will first require removing it from the chainsaw. Removal is carried out according to the algorithm described in the paragraph: “The control key of the Shtil 180 chainsaw is broken - how to fix it.”

After the engine is removed, the 4 screws securing the engine pan are unscrewed, after which it is removed. Thus, by removing the pan, we gain access to the seals and bearings of the crankshaft.

An important point when replacing oil seals is to reinstall and seal the pan.

To carry it out efficiently, it is necessary to clean and degrease the pallet and its installation location on the saw cylinder, and then coat it with sealant and install the pallet, tightening it crosswise to the required force.

When installing the pan, it is important not to confuse the location and install it in such a way that the casting to hold the oil pump housing is located in the opposite direction from the flywheel, otherwise it will be impossible to put the engine back into the saw body.

Reassembling the chainsaw after repair is carried out in the reverse order.

How to Replace the Starter Cord

Quite often the starter cord needs to be replaced due to a break. Let's figure out how you can replace it without contacting a service center.

Removing the starter from the Shtil 180 chainsaw is quite simple, without even removing the handle block; to do this, you will need to unscrew the mounting screws and remove the covers of the oil and fuel tanks. Then, slightly lifting and turning the starter, remove it from its seat.

The starter cord is wound on a special drum, which is installed in the body of the part. To replace the cord, there is no need to remove the drum; just remove the broken cord and wind a new one.

Use original Stihl cord of the correct diameter for replacement. If the cord is thicker, the number of turns of cord wound on the drum will decrease, which will lead to a decrease in the starter stroke.

After the cord is wound on the drum, it is necessary to pass it through the starter body and install the handle and secure it with the help of several knots made one after another. Next, the working stroke of the starter is checked, and if everything is in order, the part is installed in place.
