The stihl 180 muffler is attached with two nuts, promoting which you need to pull it over, it will easily withdraw.

The coil is attached to two screws, you just need to spin them to remove.

Possible malfunctions of a trimmer gearbox for grass, a gas mowing gearbox, and gearbox Motokos

In order to disassemble a trimmer gearbox for grass, you need.

  • Remove the gearbox from the pipe, loosening two conjugate bolt under the gearbox.
  • Wash the gearbox with a brush, for example, in gasoline without oil and dry.
  • Run the ends of the locking ring and take it out.
  • The second stop ring and the second.
  • Then it is necessary to heat the trimmer gearbox for grass, the motorcosa gearbox or the reducer of the lawn mower by an industrial (technical) hairdryer at the temperature of the outgoing air at 600 ° C.
  • After that, strong blows of a wooden bar on the upper part of the gearbox, knock out a driven shaft with a bearing and a gear (first you should try to knock out bearings without heating). It is only necessary to hit a wooden bar, since a metal, for example, with a hammer, can be broken down by the case.
  • In the same way we remove the leading shaft with a bearing and a gear (we strongly heat the place where the bearings are sitting and with the blows of the wooden bar on the body of the shaft, we knock out the shaft with two bearings and the gear). How to disassemble a trimmer gearbox for grass, gearbox gearboxes and gearbox motokos. In order not to heat, you can try to use the set.

The assembly of the gearbox of a trimmer for the grass is carried out in the reverse order of disassembly (assembly after buying and replacing spare parts). It is much easier to collect a gearbox than to disassemble. Everything is going, literally, with fingers. Sometimes you need to gently take up something, install stop rings and check whether the driven shaft is spinning by hand.

If you decide to replace the trimmer gearbox for the grass with not original, then in the new gearbox you should pay attention to the diameter of the pipe for which the gearbox (more than 25.4 mm or 26 mm) is intended, the diameter of the drive shaft (more than 8 mm), the size of the square shaft square (more often 5 mm or a star for 9 teeth) and security mounting on the gearbox, as well as on a nut (with left thread, more often M10x1.25).

Alexander (Priam) Stoporye Makhovik and try to crank up Fomka for the variator along the shaft, but due to the great effort on the flywheel, the duraluminum

Vasily, I shot it like that, made a cross from a square profile 20na 20, he was just getting into the grooves of the mossy, Knaus welded the tube in the ruttu, inserted the rod to the pin for 50 so that it did not push, put the rods in the opening from the side of the variator and to it and to it I wrapped a small crowbar with a jerk and it spins further, the right carving is like ordinary

Alexander (Priam) on the side of the variator inserted into the middle-type into the shaft or into any hole?

Alexander (priam) as a flywheel to stop, I understood, I understood, but I inserted a crowbar into the variator between only two bolts and with a good stop and good dope, I just shit the varik, but Potapetriel-lomic will wind right now for each bolt on the varika and will be normal.

Alexander (Priam) I remove the variator since the oil seal jumped out and hangs between the engine and the variator.Tell me how the oil seal from the side of the varik is kept like there is not even a stop ring?

Vasily (Loney) Small the same trouble, the oil seal is just putting on the shaft and the mandrel is stopped by a mandrel, he is not attached with anything, well, if the bearing is nrom.Take the seal, take the ledge at the end, make the hook from the shaft and pull it carefully, look at the bearing seporator of me, he painted and they say it so happens

Vasily (Loney) can be caused by the lark a little and smear the surface

Alexander (Priam) I already thought-Super with glue or epoxy resin to fix the oil seal

Alexander (Priam) and what kind of oil do you use?

Vasily (LONEY) Supr lux Oliva 2t 1: 40 blue in 370r

Vasily Autol, as if now there is no similar, but smoke and Nagaru a lot 1k 20 so.Terrible

Alexander (Priam) I also think to leave the M8 autol, otherwise I took off the pots.Fully is full.

Vasily (Loney) Yes, I am not far away and I live from you in 20 hours on a drill I can get from Kamensk Uralsky

Alexander (Priam) under the foot you can and faster

Alexander (Priam) Yes, safari, easily.Just the skip on the flywheel removed and put the factory.Put on these hairpins, put the board under the shooter and twisted.Right now another problem: I can’t understand how to remove another pancake to get to the omentum.

Igor (abagail) I do not remember to insert the bolt m 10 or 12 into the opening at the end of the shaft: to hook the right 20×1, 5 gas threads under the sculpent of the flywheel to install a pipe or end key 19×21 (flywheel and variator not one whole)

Igor (Abagail) The crown must be heated by the lamp Acurantly and it will pull.

Artyom (jonika) And and here is the oil, on 20l Benz 800 M8 oil, and so Ravinol, you took off the variator

Types of gearboxes for a trimmer for grass

It is worth noting that the basic components of cylindrical mechanisms are toothed cylinders. Most trimmers are equipped with worm gearboxes, but much depends on the decision of the manufacturer and other features.

A feature of the planetary type of transmission is the coaxial location of the shafts, while conical objects have a crossing placement. Gear gear is relevant only for those units that are used in certain temperature conditions. Over, for them, any mechanical damage can become a fatal.

The chainsaw engine is not started

If the mechanism does not start, it immediately stalls, check sequentially:

  • Is there a fuel in a tank;
  • Serviceability of the spark plug;
  • The purity of the air and fuel filter;
  • The purity of the sapun and graduation canal.

It is necessary to make sure that the working candle gives a spark in contact with the body. In this case, it is necessary to dry the candle channel, clean and dry the part itself. You can change the candle, but the channel still needs to be dried within 40 minutes. Check the serviceability of a high.Voltage wire, may not always have contact. A malfunction in the ignition unit during the repair of a lawn mower, do not eliminate with your own hands.

If the engine does not stall when the air filter is removed, the reason is in it. Replacement or cleaning is required

Fuel filter replaces with great care. After checking the cleanliness of the bacon, remove the muffler grid and clean the exhaust channel

What tools are needed to unscrew the crankshaft?

As noted above, when trying to unscrew the pulley from the crankshaft, the details are constantly rotated, which is why this is almost impossible to do without fixing means. In addition, getting to the crankshaft crankshaft bolt is not so simple, given that it is located perpendicular to the axis of the car.

Before proceeding with the disconnection of the pulley and crankshaft, it is necessary to prepare the following tools:

Lever for a key or head, as well as an extension cord; Standard set of automobile tools; Mount (or something similar); A jack for raising a car; “Stoop” or “goat”, which can be installed as a safety list for the jack.

When all the tools are ready, you can proceed directly to the procedure of twisting the bolt and separation of parts.

The procedure for lifting the clutch on the chainsaw

The configuration of most modern chainsaws includes a clutch of the centrifugal type. The work of these mechanisms directly depends on the torque created by the engine.The device of centrifugal clutch consists of a spring, asterisk and drum.

remove, flywheel

In this case, the rotational force from the motor is not transmitted to the drum leading the star and the tire. Gradually, the pressure of centrifugal force increases and displaces the force created by the springs. At this moment, the clutch components lose their strength and begin to contract next to the inside of the drum.

The main plus of centrifugal clutch is its instant slip at the moment when the cutting organs begin to rotate more slowly. At the same time, the chainsaw engine itself does not lose its original speed and continues to move as smoothly as before. This allows you to reduce fuel costs and reduce the risk of burrs in the CPG of the economic saw motor.

Modern chainsaws are equipped with centrifugal clutch couplings. This means that their work entirely depends on the torque of the motor, which at a particular moment in time gives out a saw.

Its main constructive elements are:

The principle of operation is as follows. When the saw is launched, the elements that are freely move in the radial direction, with the springs are tightened to the axis of the shaft. In this case, the torque does not enter the drum, which means to the asterisk and the guide.

At the moment when the centrifugal force prevails over the power potential of the springs, the adhesion elements are weakened and compressed at the inside of the drum, initiating it. Together with him, the rotational cycle passes to the asterisk and the tire-like headset itself.

The main advantage of the clutch of this type is its slippage when the cutting part is suddenly inhibition, which does not stop the engine. As a result, the “heart” drank. The engines remain intact and preservation.

Chain chainsaws, for various reasons, from time to time need repair. Of course, you can contact a service workshop or to experienced mechanics. However, many problems can be eliminated at home, having only a minimum set of skills and tools.

remove, flywheel

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

The owners of the instrument may face certain difficulties if the chainsaws are used for a long time, and the clutch details have cooked to each other.

However, in this case, the disassembly can be done with your own hands.

For many owners of chainsaws, the question of removing the clutch on a chainsaw has become more than once becoming relevant. Many chainsaws, despite multifunctionality and high performance, have simple constructions that the owner can disassemble and assemble independently. In particular, this applies to clutch, which is only repaired in specialized centers on a few models.

I use the fishing line for my site, its consumption is small. For a neat state of 6-7 acres just right.

How to replace a trimmer gearbox for grass: an algorithm of action

To replace the gearbox with a similar part from the same manufacturer, it must first be disassembled and removed from the bar. At the same time, they act according to the following algorithm:

  • Weaken the fitting bolts located under the transfer mechanism;
  • Using round.Drawers, remove two corkscrew rings;
  • Applying the puller, pull the bearings from the driven and the leading shafts;
  • Then collect the mechanism, in the reverse order by installing all spare parts.

The disassembled transmission mechanism is shown in the photo below.

If the puller is not at hand, then you can try to gently knock down the bearings. When they have stuck and do not move at all, you can heat them using an industrial hair dryer (at a temperature of 600 ° C) and remove.

Collecting a gear node is easier than disassemble it. Only a light tapping with a hammer for planting parts in place may be needed. After assembly, it is imperative to check that the driven shaft turns out by hand.

Когда есть необходимость замены передаточного узла неоригинальной деталью, тогда следует учитывать их взаимозаменяемость. At the same time, it should be taken into account:

  • The diameter of the bar (this parameter often is 25.4 or 26 mm);
  • The parameters of the drive shaft. The shape of the docking space and the diameter (its common value is 8 mm);
  • Option of consolidation of protection.

If the considered parameters coincide, then it will be possible to set a part from other models.

Timely lubrication of the gearbox will ensure its prolonged operation without repairs. In addition, modern materials protect the metal from corrosion well, increase its wear resistance. When choosing, preference should be given a lubricant recommended by the manufacturer of the operated trimmer for grass. If such compositions are not possible to purchase, then the analogs considered or other suitable in properties should be applied. When it is necessary to disassemble the mechanism during the repair, this should be done carefully so as not to damage individual parts.
