How to install the piston to the trimmer

We examined the main causes and malfunctions of the Stihl ms 180 chainsaw in which it is necessary to replace the CPG. But, as a rule, in each specific case, the reasons may overlap, and for proper repair, an integrated approach to solving the problem is required. Putting a new reciprocating saw on the saw does not always mean solving the problem. It is imperative to eliminate the causes of the malfunction and the tool will serve for a long time without problems and the need for repair..

Self-repair of the chainsaw is possible if you follow the instructions

Among the household inventory of the owner of a private house, there must be a chainsaw. an irreplaceable thing in the household, if you need to cut firewood, cut dry branches on garden trees or even a whole tree.

Major breakdowns

Before handing over a broken chainsaw to a repair service, you should try to identify the breakdown yourself and, possibly, fix it. For this, there is a chainsaw repair manual, which is always included in the delivery set. In it you can find answers on how to carry out repairs in cases when:

  • the chain broke;
  • the saw will not start;
  • the saw starts up and stalls;
  • the chainsaw works, but not at full capacity.

One of the most important parts of any chainsaw is the cylinder-piston group (CPG), which transmits the rotational motion to the drive sprocket. Despite the reliability of this unit, most models require diagnostics and repair over time. It is the performance of the chainsaw’s CPG that determines the power of the unit, its ease of starting, the presence of idle speed and the consumption of the fuel mixture.

Replacing the piston group Stihl 180.

The inner surface of the cylinder must be completely sanded and have a glossy shine, where you need to direct attention in the matter of purchasing a spare CPG for the stihl ms chainsaw. If the inside of the cylinder is damaged, it is not necessary to install such a cylinder.

Description of the piston group chainsaws Stihl 180

On the Stihl 180 chainsaw, the piston group has a diameter of 38 mm. The dimension of the CPG of a chainsaw is determined by the diameter of the piston, the cylinder is a bit difficult. In the complete set, the standard MS 180 CPG is supplied complete with a piston pin, 2 piston rings and 2 retaining rings.

How to change a piston on a Stihl 180 chainsaw

If you need to replace the old piston and install a new one, you need to know how to do this correctly and follow a certain algorithm of actions. You also need to have a small slotted screwdriver, a special Stihl combination wrench, a power screwdriver, a hammer, a soft material drift, a compressor and a Stihl piston stopper.

When starting work on replacing the piston or piston group assembly, the chainsaw must be cleaned of dirt as efficiently as possible. Further, the work is carried out according to the following algorithm:

  • The top cover is removed from the saw and the spark plug is unscrewed.
  • Side cover is removed.
  • Using a power screwdriver, the stoppers are removed from the shock absorbers of the chainsaw, after which its handle is disconnected from the body.
  • Next, you need to remove the drive sprocket and starter.
  • Install the piston stopper in the spark plug hole and loosen the flywheel nut and clutch.
  • Remove the flywheel, clutch and oil pump worm drive mechanism, which is located behind the clutch.
  • Unscrew the two screws securing the carburetor and air filter. Remove the filter, engine control lever and Stihl carburetor.
  • Remove ignition coil and muffler.

After all these operations have been carried out, it is necessary to clean the saw from dirt again, then turn it upside down and unscrew the four screws securing the engine to the chainsaw body. By unscrewing the screws, the motor is separated from the housing and cleaned again.

On the removed engine, the pallet is untwisted and removed, after which the piston assembly with the crankshaft is removed from the engine.

When removing the piston from the cylinder, you must remember how it was located relative to the cylinder.

Next, using a small screwdriver, the piston pin retaining rings are removed, and the crankshaft is disconnected from the piston.

In the case when it is necessary to replace only the piston, you can install it on the crankshaft, and then mount the piston pin circlips, while positioning them so that the break point of the circlip is directed downward. This is necessary in order to exclude the possibility of spontaneous popping out of the circlip during engine operation (according to the manufacturer’s instructions Stihl). After that, the compression rings are installed, the cylinder is lubricated with engine oil and the engine is assembled..

The work of installing the piston into the cylinder must be carried out with utmost care, since the compression rings are fragile and easily break.

The crankcase is installed on the engine, a sealant is used as a gasket, after which four fastening screws are mounted and tightened crosswise. Further, the engine is installed on the body of the chainsaw. Subsequent assembly is performed according to the reverse disassembly algorithm..

Algorithm for replacing a piston chainsaw

If it is time to replace the CPG of the chainsaw, you need to know that for each specific model there is an individual algorithm of actions. To facilitate disassembly / assembly work, you must prepare a spark plug wrench, a large flat screwdriver, a hammer, a compressor for cleaning the unit parts, a set of open-end and socket wrenches. Regardless of the manufacturer and design features of the model, before removing the cylinder of the chainsaw, the following work must be performed:

  • Dismantling the upper protective cover;
  • Unscrewing the spark plug;
  • Removing the side cover;
  • With the help of a large flat screwdriver, the stoppers are removed from the shock absorbers;
  • In the channel of the candle we place a lace to fix the crankshaft and unscrew the clutch and flywheel nut;
  • Dismantling the drive chain sprocket;
  • We remove the carburetor with an air filter;
  • Removing the ignition module and exhaust system.

After removing it from the base of the power unit, unscrew the pallet and remove the crankshaft with the piston from the cylinder. Using plumbing tweezers or a screwdriver, we dismantle the piston pin stoppers.

Before dismantling the piston, it is necessary to remember its location in the cylinder so that later you do not waste time on re-disassembling and assembling the power unit.

Chainsaw pan sealant

Before starting the assembly, it is necessary to clean the parts and assemblies of the unit from dirt, sawdust residues, dust with compressed air, rags and other means. The first step in replacing a piston chainsaw is to install a piston on the crankshaft. We fix it on the connecting rod with a steel finger included in the delivery of the CPG. In order to prevent arbitrary falling out of the retaining rings, it is recommended to install them with a cut down. Next, we mount the compression rings on the piston, but due to their fragility and fragility, this operation must be approached as carefully as possible. To prevent the formation of scratches before installing the piston in the cylinder, the piston must be lubricated with oil. Before installing the crankcase (pallet), you will need to degrease its mounting surface and apply a layer of heat-resistant sealant. We assemble the chainsaw in the reverse of the algorithm described above..

When a piston needs to be replaced

There can be quite a few reasons why the piston needs to be replaced, as well as a completely piston one, but they can all be divided into natural and resulting from improper operation. Natural, this is the wear resulting from the long-term operation of the Stihl 180 chainsaw. There are much more artificial ones, for example:

  • overheating of the engine and the appearance of thermal seizures;
  • ingress of a foreign body into the cylinder and the appearance of mechanical scoring;
  • breakage of the piston ring as a result of exceeding the maximum engine speed;
  • breakage of the piston skirt due to overspeed;
  • the use of low-quality fuel, as a result of which the piston group of the chainsaw wears out from the side of the intake channel in the cylinder;
  • operation of a Stihl chainsaw with a dirty fuel filter, as a result of which the percentage of oil in the fuel mixture is reduced;

It is necessary to diagnose the CPG if the Stihl ms 180 suddenly lost power or does not start, while the starter of the tool does not turn. If the starter cranks, but the saw does not start, while there is a spark and the fuel enters the cylinder properly, it is necessary to measure the compression in the engine.

If there is a suspicion of problems with the CPG, it is advisable to contact a service center authorized by the manufacturer, since only there they can accurately diagnose the malfunction without full analysis and, if necessary, carry out a high-quality repair.

9.5 – 11 atm. It is considered a normal indicator at which the Stihl chainsaw starts up properly and delivers maximum power, if the compression is lower, there is a possibility that there are scuffs on the cylinder-piston group, or its wear is quite large. In any case, with reduced compression, for further diagnostics, it is necessary to completely disassemble the saw.

It is possible to determine the presence of scoring on the piston, as well as the breakage of the piston ring, if you remove the muffler and conduct a visual inspection of the visible part of the piston, while the rings can be checked for elasticity by pressing on them with a small screwdriver. There will be slight movement on the working rings, a defective or jammed piston ring will not move.

Piston

Pistons (eng. Pistons) – block-mechanisms that allow, when a redstone signal is given, to push blocks forward. They exist in two versions: regular and sticky (which, when the signal is turned off, can take the block back in front of itself).

Restrictions [edit | edit code]

The piston cannot push (or pull, in the case of a sticky piston) more than 12 blocks or certain blocks (see below; in particular block entities), as well as outside the map (into the Void or to a height of more than 255 blocks). In such cases, the head simply won’t pop out. When turned off, sticky pistons will not pull non-movable blocks or slime blocks with more than eleven movable blocks attached.

As indicated in the table, the pistons will not move blocks attached to other blocks as they will detach and fall out like an object. But there are exceptions:

  • Luke
  • Any rails. Moreover, after moving, they must stand on a solid block, and he does not move at the same moment. [1] The rails are reoriented after moving, as with manual installation.
  • Carpet

Glazed ceramics do not adhere to sticky pistons. She can only be pushed.

    3 sticky pistons are found in jungle temples as part of a puzzle mechanism.

    Using [edit | edit code]

    If the piston is powered with a redstone signal, its wooden head will come out, which will try to push the blocks in front (if they are movable and there are no more than 12 of them). The extension lasts about one and a half ticks of red stone (0.15 seconds) and is accompanied by a sound audible at a distance of 15 blocks from the piston along any axis. Moreover, if there are entities on the way, then if there are no blocks on their way, they will also be moved (moreover, if the moved block is a block of mucus, the entities will be discarded), otherwise the head or block will pass through them; in the case of a block, entities can be strangled by the block if it is solid.

    When the piston is turned off, the head will move back. Moreover, if it is a sticky piston, then the head will try to move the block “glued” to it with it. The sticking effect occurs only when the head is moved, so falling blocks after moving will still fall if there is free space under them; also, a block that was moved by a sticky piston can be moved by another piston without any complications. Also, if the sticky piston loses power before how he has time push out block, then the piston “peels off” from the block, which remains in its new place. If nothing is pushed out by such a piston and the power is still turned off prematurely, then the block that was destined to pull it along with it will be shifted as usual (though somewhat faster).

    The piston head at the time of installation points in the direction of the player who installed it.

    How to correctly put a piston on a chainsaw

    The rings and the piston are the first to wear out, and usually only need to be replaced. With severe piston wear, the cylinder must be bored. It also loosens when the piston wedges in the cylinder, forming deep scratches on the walls of the latter. There is nothing wrong with that, and if your new cylinder has gone through the correct bore (for which you will need to pay only about 10), it will need a repair kit of rings with a new piston. Such rings are marked with a 0.25 mark. The second bore is 0.5, respectively, etc. to one.

    After purchasing the piston, you need to assemble it. In the kit, as a rule, you will find the piston itself, two compression rings, a third thin corrugated ring (more on its purpose), a piston pin and two piston pin retaining rings.

    Now about the third ring in the kit. Its purpose is to spring the lower compression ring. It installs it under it itself, and usually does not carry any benefit during operation.

You can throw this ring away, or you can put it, there is no difference. Many piston manufacturers do not have one at all..

    It’s time to put everything in place. Depending on the scooter model, the compression rings may be the same or differ in thickness and cross-section. Most pistons for Honda scooters, for example, have different rings, where the upper is thinner than the lower one and has a different cross-section..

    It is imperative to pay attention to this when installing, the top is thinner and sharpened at an angle.

    Also pay attention to the inscription on the ring (usually the letter T or the size of the repair), the inscription should always be on top, that is, opposite from the finger. First you need to put on the bottom, then the top. In this case, you do not need to stretch and bend them. These manipulations must be carried out carefully..

    There are locks in the grooves for the rings that prevent the rings from turning during operation, therefore the ring gap must be exactly in these locks, otherwise you will not stick the piston into the cylinder.

    And the last important point is the arrow (1) on the bottom of the piston or the inscription EX. Both the arrow and the inscription must be directed towards the exhaust (2). In this case, the ring locks will be on the side of the petal valve. How to correctly install the rings on the piston of a two-stroke scooter published on 25.08 | author: scooter.rv.ua in the installation of rings on the piston of a two-stroke scooter, however, like a four-stroke, there is nothing. If the locks are put in the direction of the exhaust, the piston will not last long, the rings will be pulled into the exhaust window and gradually grind it off.

    When installing the piston pin, pay attention to the condition of the cage (bearing), it may need to be replaced. Before installing the gudgeon pin, install the circlip on one side prior to installing the piston (usually the side where you will not be comfortable with the pin and second circlip). Then put the pin with the bearing and the second circlip, when it is fixed in the groove, it will emit a certain click.

    That’s all, now put on the cylinder, not the piston (remembering to check the condition of the gaskets and lubricating the piston and cylinder walls with engine oil), the cylinder head and tighten the bolts alternately in a crosswise order.
