Silent muffler for power tiller with his own hands

How to make a single axle tractor muffler with his hands?

If you decide to make your own muffler on a single axle tractor due to a breakage or poor quality of the factory part. first of all you need to get hold of a minimum set of tools. For work you will need:

After it is worth carefully familiarizing yourself with the device of the factory muffler, in order to understand the design itself, note the weaknesses of the part. Usually such vulnerable places are flange mounts, which are made of low quality metal or are of insufficient thickness, partitions of the expansion chamber, narrow pipes, which complicate the exhaust, reducing the productivity of the whole power tiller.

Homemade Exhaust MUFFLER For Trimmer ?

Actually the stages of manufacturing and assembling a new muffler should be performed in this sequence:

• Flange attachment. Usually the thickness of the workpiece is selected in the region of 8-12 mm, but the thicker. the better. Especially, if the future design foresees upwards direction of a muffler
• Expansion chamber. In essence it is the main building block in the silencer. Looks like a kind of thickening with baffles inside. It is these baffles that reduce the velocity of the exhaust fumes and noise produced by the power tiller. To make a silent muffler for a single-axle tractor, it is necessary to place at least 3 baffles in the expansion chamber. Too many of these baffles will certainly help quiet your single axle tractor, but it will interfere with engine operation.
• Exhaust pipe. This part must have thick walls and not be too heavy so as not to ruin the whole construction. The pipe diameter should be the same as the engine exhaust. it will keep the whole fuel system of the power tiller working smoothly.

Muffler for power tiller: causes of breakdowns and repair with their own hands

When an unproblematic single axle tractor starts to malfunction, the owner falls into a certain stupor and starts looking for the cause of the problems. The emergence of this situation is doubly annoying when there is a lot of work and no time for downtime.

It is not uncommon for trouble to arise with the muffler, which for certain reasons begins to make strange noises or at all behave suspiciously. The main thing is not to panic, and deal with everything with a cool mind. Let’s get acquainted with several problems that occur most often.

a single axle tractor shoots out the muffler: what to do?

The owner of such useful and versatile machinery needs to know that the appearance of muffler malfunctions can happen due to:

• Thin and low-quality metal;
• Frequent bumps;
• of excessive loads;
• difficult work;
• of the ill-conceived plan.

Often the cause of the appearance of muffler pops are skips in the process of sparking and spark plugs. To get rid of the problem you need to unscrew the spark plug, unite its body and the mass, cranking the crankshaft by means of the starter crank.

At the same time you should pay attention to whether there is a spark. If even after these manipulations the situation does not change, it is advisable to thoroughly clean the spark plug.

How to make a new muffler

Most users prefer to make their own silencer for the power tiller. This is due to the simplicity of the construction itself and the high efficiency of the manufactured part. As a rule, the owner himself chooses the thickness of the material from which the new part will be made. This eliminates vulnerabilities and increases the reliability of the entire assembly. It is worth noting that in order to make a homemade muffler on a single-axle tractor, the following set of tools will be required:

If all tools are available, you can begin the manufacturing process itself.

After it is necessary to familiarize with the device of a factory muffler, in order to understand the construction itself, to mark weaknesses of parts. Usually such vulnerable spots are mounting flange, which is made of low quality metal or has insufficient thickness, septa of the expansion chamber, narrow pipes that complicate the exit of exhaust gases, reduce the productivity of the whole motobloc.

Actually, the steps of manufacturing and assembly of the new muffler should be performed in this sequence:

• Flange mounting. Usually the thickness of the billet is chosen in the region of 8-12 mm, but the thicker. the better. The muffler is designed in an upward direction, especially if it is going to be built in the upward direction.
• Expansion chamber. In fact, this is the main part in the muffler. It has the appearance of a kind of thickening with partitions inside. It is these baffles that reduce the velocity of the exhaust gas flow and reduce the noise when your power tiller is running. To make a silent muffler for a single axle tractor it is necessary to place in the expansion chamber no less than 3 baffles. Too many of these baffles, of course, will help make your single axle tractor quiet, but it will interfere with the engine.
• Exhaust pipe. The part must have thick walls and not be too heavy to keep the whole assembly from collapsing. Its diameter must be the same as that of the engine exhaust pipe. This helps keep the fuel system of your power tiller working properly.

Homemade muffler with a pleasant sound

I do not know how now, but in the past many people knew that the old car fire extinguisher is an excellent blanks under the spigot. The story is simple: what was not done with a native muffler’s can on the piit. it was of little use. I changed the muffler stuffing and made a Yamaha-type flute, but it still sounded nasty, rattling and loud, in general. a shuffle.

Put a full-fledged muffler from the pit is possible, but you have to shorten, reweld the mounts, but you know: to buy a barrel for 5 and even reweld it all, I had no special desire, but the desire to get rid of the native muffler still did not leave.

So back to the fire extinguisher. One was lying, gathering dust in the garage for a long time, but here’s for the manufacture of direct current need two And so, one beautiful May morning on a small river, among the snags on the surface was spotted the coveted second extinguisher. Exactly the same as the first one, and now there were two of them. Well, you know what that led to.

We take the most attractive tool in a garage, with affectionate name “bolgarochka”, and we saw evenly the bottoms of extinguishers.

Next, we take a pipe fortykovku, slicing balgarkoy gas-distributing slots or, if not lazy, drill a billion holes. Then weld one end of the pipe to the part of the muffler where the outlet hole will be.

With an outlet even nothing to do: the place of attachment extinguisher nozzle and just fine fit and diameter is necessary.

Now we go to the kitchen and tear up the covering of refrigerator ZIL, ripping out glass wool. Only when working with glass wool wear tight clothing and gloves, otherwise you will itch for two days, and if these two days you want to cope with the natural urine. Yes, yes, the itch will be there too In general, we take glass wool, and as densely as possible stuff the outlet part of the can.

Then we proceed to the inlet part. Here in it just a thread should be cut so that through it passed the pipe fortykovka, well, and, naturally, it is also stuffed with glass wool, the denser, the better.

Well it’s just a matter of a little: we weld both parts together and weld a pipe to connect it with a standard muffler.

I did not bother with the mounts to the frame, and why? Made two points of fastening to the luggage frame (I couldn’t get sturdier): this fastening was able to withstand rollover on asphalt and the can became a boogie))))

End of the can is up to you. I made pipes of smaller diameter. And it looks quite good)

The sound, let me tell you, turned out amazingly great! Even though it’s a blunt! At idle it can not be heard at all, even the ebbs are louder, and on the move is just the most beautiful sound. a soft growl without a dull metallic rattle and yelling.

And here is the final look) Plastic does not burn, the sound is nice, with a native spigot did not do anything. What more do you need?)))

Whichever option of damping exhaust you have not chosen, you should understand that you can just buy a ready-made solution if finances allow, and you can muffle it with your own hands, making a device from improvised means.

A small part of car owners would like to have a sporty sound exhaust. Another overwhelming number of drivers are puzzled by the question of how you can make a quiet muffler. It is comfortable to drive in ts, when not enough outside sounds are seeping into the interior of the car. The muffler makes the noise background, but it can be lowered and the effect you get is impossible not to see.

How to make a silent muffler with your own hands

Before we start upgrading the exhaust system, let’s understand what causes excessive exhaust noise. In the combustion chamber of the engine cylinder with each stroke of the piston there is a microburst, it is accompanied by a sharp expansion of gases after the blast wave has done its work, moved down the piston, opened the exhaust valve and rushed through the exhaust system.

The exhaust system has a dual nature of noise:

To combat the noise, the weight of the parts should be increased. The thicker the metal, the less noise and vibration. That’s why the exhaust manifold is the first to take the red-hot gases from the cylinder head. Many car owners had the opportunity to compare the weight of a foreign and Russian car, they noted that the imported cars details of the exhaust system is significantly heavier. For this reason, “our” cars are the least comfortable in sound-noise comparisons.

In the exhaust pipe special elements. mufflers and resonators, help to reduce the speed of the gas. The resonator is first in line. Under pressure the gases pass into the enlarged part of the pipe, there they lose some of their energy and then move with the least momentum. Exhaust gases in the muffler labyrinth system quite lose energy and dissipate. On an imported car, the silencer has some kind of separate housings.

What is the resonator and exhaust manifold

wishing to modernize the exhaust system, in order to reduce the sound of the exhaust, you must be prepared in substance and at the technical level. A set of car mechanic’s tools is useful for us. In addition, it will certainly be useful:

The most affordable method in the criteria of the average garage to make a soft muffler. you must include in the existing system is already exhaust extra resonator.

There are two options for upgrading the exhaust system: the installation of the site between the main resonator and industrial silencer extra resonator or manufacture with their own hands such a device.

When considering the issue should be taken into account that at least some of the option entails a variety of costs. If the car owner has an unlimited budget, you can buy a new resonator, then cut out a part of the pipe and weld it on the vacant space. The second method is more interesting and it will tell you more about it.

Making an additional resonator consists of such steps as:

• From a piece of sheet steel or thin-walled metal pipe in the form of 2 halves make a case (barrels);
• on the section of the exhaust system pipe, which corresponds to the length of the housing and is behind the main resonator of the holes;
• connect the halves of the body to the holes on the pipe and weld them together;
• put basalt mineral wool in the cavity of the new casing;
• weld the end parts of the resonator.

finally treat the welds after welding, clean them, degrease the new resonator, and if possible, take it and paint it with heat-resistant paint.

When the issue is solved and a silent muffler is made, the problem areas become apparent. You should keep in mind that while making a “quiet” exhaust system, it leads to weight increase of the entire construction.

As a result, the car owner takes additional measures to strengthen the rubber shock absorbers and mountings. It is also necessary to take into account that the balance of exhaust gases and incoming air into the engine has changed. After the modernization of the exhaust system is made, you need to carry out various modes of the engine tests and make additional adjustments to the air filtration system and fuel supply.

A silencer is needed to reduce the noise created by the flow of exhaust gases, effectively blocking their path. And ideally there should be no obstacle for the gas exhaust from the cylinder.

The “basic” breakdown of any power tiller

During the active use of the power tiller, many users have noticed a very weak silencer design. Various bumps, constant shaking and hard field work, affect this vulnerable place. The metal is too thin or the mount is ill-conceived and often breaks at the most inopportune moment. Almost all power tillers, regardless of cost and manufacturer’s firm, suffer a breakdown of such an important part as the muffler. If it breaks, the single-axle tractor won’t start, loses power, stops, shoots or makes other unusual noises.
