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

When a trouble-free singleaxle tractor begins to malfunction, the owner gets into a kind of stupor and begins to look for the cause of the problems. It is twice as annoying when you have a lot of work to do and no time to idle.

Often it is the muffler that is in trouble, for some reason it starts to make strange noises or behave suspiciously. The main thing is not to panic, and deal with everything with a cool mind. Let’s get acquainted with a few problems that occur most often.

The hay shredder: 8 photo examples, made by our own hands

Hay chopper. a small relief in the life of the owner. The main thing is that you can do yourself, having spent two or even three times less money than buying in the store. Know a bit about technology or know how to use the internet is enough. Or preferably both.

One of the possible variants of the hay shredder made by your own hands. The motor can be taken from unnecessary equipment. A barrel can be used as a hopper. The shredding will be due to the knives, which can be requisitioned from the kitchen combine. You only need to find a smooth shaft and weld some pipes for supports.

One of the options with a barrel. Of course, you have to kill a lot of time for such a model. But it’s cheaper than similar products in the store.

People craftsmen manage to give even a broken vacuum cleaner a second life.

In Eisk, a similar unit sells for 9 thousand.

That’s what the presence of a life-giving locksmith’s kit does.

Power of 5.5 kW. Not worse than foreign analogues.

Creation of a muffler with own hands

Important fact: since the most common weak point of the specified part is the attachment of the flange, you should choose a stronger and thicker metal for its performance.

  • Since this point is the most important, it is worth starting the work. Suitable thickness of the workpiece is 8-12 mm, much depends on the future design. If the part is expected to be guided upward, a stronger and thicker piece should be chosen. In order for the flange mount to fit tightly, it is important to make a special adapter, similar in design to the element located on the engine exhaust manifold;
  • The next step consists of forming an expansion chamber. It is more like a thickening with 2-3 baffles (you can more), contributing to a reduction in the flow rate of exhaust gases and noise level. You can not overdo with the number of baffles because then the device will be difficult to start and function fully;
  • The creation of an exhaust pipe is perceived as a final detail. It is desirable to choose the element of the same diameter as the exhaust pipe.

As you can see, the creation of a muffler for a motor-block with their own hands is not such a difficult process, so it can be implemented even by people without much experience.

Malfunctions that can occur during the operation of both “native” muffler, and homemade

The problem The reason Solution
Occurrence of individual suspicious pops in the muffler Misses in the supply of spark in the spark plug After unscrewing the spark plug, it is necessary to connect the spark plug body and the mass, twisting the crankshaft with a crank and checking for the necessary spark. Clean the spark plug if necessary.
Black smoke from the machine’s muffler In fact, there are many reasons for this, but the most common ones are the use of low-quality oil or contaminated injectors You should change the fuel and check the injectors, ridding them of unnecessary black particles
Excessively loud noises coming from the muffler Lightweight parts Increased weight of the elements will allow the muffler to operate with little noise
Muffler gives off pale smoke and white deposits on the electrodes A lean fuel mixture is getting into the carburetor Adjust the carburetor

If you use this table you can quickly resolve the problem and enjoy your power tiller again.

Smoke coming out of the power tiller’s muffler and black smoke: looking for the cause and solution

Many experts believe that such problems appear due to incomplete combustion in the unit. It is not excluded the detection of skipping in the ignition, the use of an over-saturated mixture, a drop in power or overheating.

If after trying to start the engine not only flames appear, but also black smoke, then we are talking about the use of low-quality oil or serious contamination of the nozzles. Naturally, it is desirable to buy a better lubricant and thoroughly clean the nozzles from all unnecessary.

When the muffler in addition to the above points also makes a serious noise, and a person wants to make it quiet, then it is necessary to increase the weight of the parts, because such problems often arise because of the lightness of the components.

Familiarize yourself with other problems that arise with mufflers Neva, Centaur, Garden Scout, etc. п., and their solution is possible thanks to the video below, where the expert presents everything in an accessible way and gives answers to the most frequently asked questions.

How to make a flare from a fire extinguisher at home

Straight-line mufflers are made a little differently. You will need insulating heat-resistant material and a pair of pipes, which vary in diameter. The smaller tube should be the same size as the components of your old muffler. First you need to dismantle the old part, remove all the baffles from the tank.

Then take a thin tube and make a hole around its perimeter. Place it in another tube and fix it by welding them together. Install in the tank the resulting. Now fill the tube space with insulation and weld the vessel. Now, to reduce the noise, wrap the tubes with an absorber and cover with a steel sheet.

Possible malfunctions of the resonator

Faulty muffler resonator contributes not only to an increase in noise during engine operation, but also to a decrease in its power, as well as the penetration of exhaust gases into the car interior. The following signs are indicative of a broken device:

  • unsatisfactory muffler performance due to failure of the resonator. An indicator of this is an increase in the noisiness of the car.
  • The appearance of rattling metal sound. This is due to the destruction of the inner part of the resonating block, which leads to a violation of the attachment of one of the non-working chambers.
  • decrease in the engine power. Occurs due to reduced flow capacity of the supplementary silencer.

Under the influence of high temperatures, the products often burn through, and a visual check can determine their integrity. If one of the above signs of malfunction is detected, the resonator should be replaced. You do not have to buy the original, you can pick up one of the universal resonators. Applying to a car repair shop will require a certain cost, so it is cheaper to change the resonator yourself. But in the absence of skills, how to check its performance, it is better to trust the experts. To avoid unpleasant surprises, it is recommended to make periodic diagnostics and timely maintenance.

A properly functioning muffler resonator provides not only comfortable operation of the car, but also the appropriate parameters of the engine, which affects its life span.

Power gain

The power here in the form of an error, namely you can count on 34% (maximum). Of course, if you have properly tuned exhaust system, putting this tape, then it will not be bad, plus the sound will be deep.

BUT hope that the raise will be 510% is not worth it, once again I will stress. as practice shows a MAXIMUM of 3 percent (I assume 4, no more)

If you just put a SAUK and wrapped it with this thermocouple (without removing a catalyst and replacement of resonators), the increase may be generally not noticeable.

Step by step instructions for making

Before you make a muffler for the car yourself, take care of two important things that are better to order from a turner: end caps and baffles. With the rest you will not be difficult to deal with yourself.

To make a muffler on the car and successfully install the self-made, you need to adhere to the recommendations:

  • Take measurements, form the jar of the assembly from the metal billet.
  • Drill holes in the can pipes.
  • Weld the pipes to the reflectors and baffles.
  • Hook and engage the shells and end caps.
  • Install the fasteners.
  • Fasten the finished part.

After the installation of the new exhaust device, the sound of the engine may change: become stronger or quieter, which depends on the quality of the work.

Manufacturing steps

Creating a muffler for your power tiller with your own hands, you need to start with mounting. The optimal thickness of the workpiece, can range from 8 to 12 mm, depending on the intended design. If by design, the part will be directed upwards, you need to choose a thicker billet. For a tight fit flange mount, you need to make your own adapter, similar to the one on the engine exhaust pipe.

After that, you can start making one of the most important parts. the expansion chamber. It looks like a thickening with many baffles, which reduce the velocity of the exhaust gas flow and thus reduce the noise. Do not make a very large number of baffles, in the future it may prevent the engine from starting and adversely affect its operation. Standard self-made mufflers, have 2-3 baffles.

The final detail. the exhaust pipe that goes directly into the muffler. It should not have too thin walls, but at the same time not be too heavy. This can ruin the entire structure and harm the engine. It is best to choose a pipe of the same diameter as the exhaust pipe that comes out of the engine. This will ensure the correct operation of the entire system.

To make a homemade quality muffler for any power tiller with as little noise as possible is an easy task that everyone can do. They can be of different shapes and designs, but the main task is still to suppress excessive noise and free exit of exhaust gases.
