In detail: do-it-yourself gas generator repair from a real master for the site my.housecope.com.
A portable power generator is an indispensable source of energy in conditions where there is no possibility of connecting to electrical mains or the supply of electricity through them stops. They use regular motor gasoline as fuel.
A portable power generator will be useful wherever there is no permanent power supply, for example, on a trip to nature.
Diesel generators have a large mass, so they are installed permanently as a backup source of electricity. Their gasoline analogue is much lighter, therefore it is quite mobile and is often taken with them to remote hard-to-reach places. Therefore, in the event of a breakdown of the gas generator, it is extremely problematic to call repair specialists; it becomes necessary to repair it yourself, with your own hands.
Portable gasoline power generator.
Such a machine is a mechanism for generating alternating current based on the synchronous rotation of its elements. Moreover, such a current, depending on its model and power, can be either single-phase or three-phase. The first has the ability to generate a voltage of 220 V and supply current to a single-phase load, which is necessary for electric lighting and the operation of most household electrical appliances. The second one can give a load in three phases and provide a voltage of 380 V, which makes it possible to connect welding machines in the first place.
The gas generator consists of an electric generator and a gasoline engine that supplies it with energy. They are connected to each other by a special elastic coupling. A metal box is installed at the electric generator, where a device for turning it on, devices for measuring operation parameters and automatic fuses in case of short circuits are mounted. A gasoline engine can have from 1 to 8 cylinders, depending on the required power, and can also be two- or four-stroke. The latter are used more often because they are more economical and have greater efficiency. The switching method can either be from a spark obtained mechanically using a manual drive, or from a battery.

The main causes of failures in the operation of a portable gas generator can be either a breakdown of the engine or a failure of the electric generator. To find out the specific cause of the malfunction, one by one, you will have to check all the nodes that can cause a failure.
Scheme of the internal structure of the generator: 1. Fuel filters. 2. Crankshaft. 3. Air filter. 4. Part of the ignition system. 5. Cylinder. 6. Valve. 7. Crankshaft bearing.
In addition, the load on the generator may exceed its capacity. Then you need to turn it off and check the work. If, during the operation of the unit, smoke begins to rise from it and a burning smell appears, it means that a short circuit has occurred in the winding, then self-repair is extremely problematic, a complete rewinding of the windings is needed.
VIDEO In general, repairing a gas generator on your own is quite affordable even in the field.
Gasoline generators, even if they are made in China, very reliable with proper care . However, during their operation, small problems can occur, which can usually be quickly fixed by hand. Serious breakdowns, if the owner knows the device and the principle of operation of the generator, will also not be able to disable it for a long time.
If you arrange the possible malfunctions of the gas generator in a kind of rating, you get the following list:
Failure or contamination of the spark plug: difficult or impossible to start, unstable operation.
Clogged carburetor: Difficult starting, excessive fuel consumption, unstable operation under constant load.
Ignition coil failure: no spark, no start.
Starter failures: breakage, cable bite, ratchet destruction.
Violation of valve clearances: difficult start, increased noise during operation.
Brush wear (on synchronous generators) - no output voltage.
Malfunction of the speed controller: floating engine speed, dips when changing the load.
Wear of the bearings of the crankshaft and the rotor of the generator - an increase in the noise of operation, oil leakage.
Wear of the cylinder, piston rings - difficult starting of a cold engine, excessive oil consumption.
It does not take into account breakdowns that are the result of a gross violation of the rules for operating the generator: for example, scuffing on the crankshaft journal due to insufficient oil level, burnout of the generator windings or voltage converter (on inverter gasoline generators) with frequent overloads.
In fact, malfunctions of a gasoline generator can be divided into three groups: mechanical, electrical and fuel/ignition system faults .
Difficulty starting the generator, which manifested itself suddenly and is not accompanied by an increase in the noise of the engine, is a clear sign of either deviations in the operation of the carburetor (too lean or rich mixture) or a faulty ignition system (weak or intermittent spark formation). Since the diagnostics of the state of these systems are interconnected, it is combined into one section.
Remove the spark plug and inspect the deposits on its electrodes.
Dense and dry black soot - A sign of a rich mixture (faulty carburetor, clogged air filter);Oily black soot - a sign of severe wear of the piston rings, oil enters the combustion chamber;White soot - a sign of running on a lean mixture, it is necessary to check the carburetor.Brick brown soot - normal for carbureted engines.Red, green-red soot - a consequence of working on low-quality fuel.It is easy to check the performance of the ignition system itself because of its extreme simplicity: turn on the ignition, insert a known-good spark plug into the candle cap and, placing it with a skirt on the nearest metal part of the engine, turn the manual starter sharply. If there is no spark, disconnect the ignition switch and the oil level sensor in turn from the ignition coil: if there is still no spark when both elements are disconnected, replace the ignition coil.
If the spark is present and has sufficient strength (white or blue-white), remove the spark plug after several attempts to start. A spark plug flooded with gasoline is a sign of over-enrichment of the mixture, a dry one is a sign of a lack of fuel.
Sometimes, after long storage, the needle and float of the carburetor stick and do not allow gasoline to flow inside. A few times abruptly, but do not hit the float chamber cover very hard and restart.
The most common carburetor malfunction is its contamination. The ingress of dirt into the air channels leads to a re-enrichment of the mixture, in the fuel jets - to depletion. Dirt on the float shut-off needle leads to loss of tightness and overflow of the float chamber, which will be immediately noticeable by fuel leakage from the carburetor.
Consider the maintenance of a carburetor using the example of a Honda GX installed on engines - its design is typical for a gasoline generator.
Remove the float chamber cover (4). Wash it in gasoline or aerosol carburetor cleaner - dirt and deposits accumulate on its bottom.
Do the same with the gas cock sump (22).
Check if the gas valve is blown in the "open" position.
Remove the float shaft (3), remove the float and locking needle (2). Blow out the channel with air.
Blow out the fuel jet (25), emulsion tube (11) and all carburetor passages with an aerosol cleaner or compressed air.
Turn out the adjusting screw (5), blow through its channel. Then turn it all the way in and loosen it, depending on the type of air filter, by 2 (foam rubber, paper filters) - 2.5 turns (cyclone filters).
Assemble the carburetor.
The electrical system of gas generators is quite reliable. Most often, you will encounter two problems: no battery charging on generators with electric start or lack of voltage at the output of the generator .
The lack of battery charging is a consequence of the failure of the rectifier or low-voltage winding. Checking this system with your own hands is simple: connect a 12-volt light bulb in parallel with the low-voltage winding of the generator and start it. A burning light means that the generator itself is working properly, and the rectifier needs to be replaced.
The absence of voltage at the generator output is most often the result of brush wear. Remove them and assess the degree of wear, replace if necessary. If your generator is an inverter type, check if the voltage comes to the input of the converter by connecting a low-power 220 V lamp in parallel with it.

One of the routine maintenance provided for in the operating instructions for gas generators is the control and adjustment, if necessary, of valve clearances. An increase in clearances in excess of the norm will lead to a decrease in engine power, an increase in noise during operation. The most dangerous is the decrease in the gap, since it is not audible during operation, but pinched valves, especially the exhaust, begin to burn rapidly. As a result, the engine starts to work unstably and when the plate burns out, it stops starting.
Valve Adjustment Procedure pretty simple:
Remove all components that prevent the removal of the engine valve cover.
Remove the spark plug.
Remove the valve cover.
Set the crankshaft to the top dead center of the compression stroke by the mark on the flywheel (if any) or by controlling the movement of the piston through the spark plug hole. Do not confuse compression TDC (both valves are closed ) with exhaust TDC (exhaust valve closes, intake valve opens ).
Loosen the locknuts of the adjusting screws and use a flat feeler gauge inserted between the rocker arm and the end of the valve to set the clearances by turning the screw. Usually, a gap of 0.2 mm is adopted for the exhaust valve, and 0.15 for the inlet valve (check in the operating instructions).
Tighten the locknuts and rotate the crankshaft twice to TDC. If everything is done correctly, at the next dead center both gaps will go away, after another turn they will take on the set value. The gaps that increased after the first revolution are a sign that they were adjusted at the TDC of the exhaust stroke.
Assemble the generator.
Manual starter malfunctions - perhaps most common mechanical problem . Either the cable breaks, or the starter refuses to reel it in due to a broken return spring, or the ratchet does not turn the crankshaft.
Remove the starter by unscrewing the bolts around the perimeter of its casing. By unscrewing the screw (1), the ratchet mechanism can be removed. Check its cams (4) and return springs (5). Then carefully remove the pulley together with the spring (7). Replace broken cable or broken spring, depending on what caused the repair.
When assembling the starter, care must be taken to ensure that the spring remains engaged with the casing and pulley while it is being reinstalled. The rope must be fully wound on the pulley. With the ratchet in place, check the cable travel and how the starter returns to its original position.

Sometimes it happens that the generator needs to be started urgently, and the manual starter failed at that very moment.If necessary, there are several ways to emergency start.
The ways listed below unsafe !
Remove the starter cover. Below it is a flywheel with a cooling impeller, attracted to the crankshaft with a nut. To make it spin, you can:
After winding the rope around the flywheel, use it in the same way as the rope of a manual starter. Keep in mind that if it catches on the fan blades, when the motor starts, this rope will turn into a whip whipping in all directions, so be careful. Stand so that the rope cannot get on your hands or head.
Low-power engines can also be started manually: turn the crankshaft several times with the ignition off, turning the pulley with your hands in the right direction. In this case, the gas valve must be open, and the damper of the starting device must be closed. After that, turning on the ignition, bring the crankshaft to the compression TDC (you will feel an increase in effort on the flywheel), and then turn the pulley with a sharp jerk so that the spark energy is enough to ignite the mixture.
A powerful cordless drill and a head with an extension cord from the tool kit are a good replacement for an electric starter in a hurry. Clamp the extension in the chuck, put a suitable size head on it and unwind the crankshaft by the flywheel mounting nut. True, in this way it will be possible to start only a low-power generator - for an engine with a large amount of torque, a drill is not enough to turn it on the compression stroke.
A number of malfunctions, alas, are quite difficult to fix with your own hands without having sufficient qualifications: for example, a faulty inverter converter or voltage regulator can only be repaired if you have a good understanding of the principle of operation and circuitry of such devices. Not every owner of a gas generator will take on the engine overhaul, although this is not as difficult as it might seem.
In this case, you should contact a specialized repair shop. The coordinates of workshops in your city can be found on the Internet or in stores selling gas tools.
In large cities like many workshops Here are just a few of them:

Checking the generator for noise
If, when the gasoline generator is turned on, it starts to shoot from the muffler, a different noise occurs and flashes are visible when the gas is turned on, then we will try to identify possible causes of the gas generator malfunction:
First, the spark plug has failed;
The second cause of the malfunction is the incomplete combustion of gasoline in the cylinders;
Or not tight closing of the exhaust valve and the passage of burning fuel into the muffler;
downed ignition angle or valve opening, this gives flashes.
Repair Methods for Gasoline Generators
Fix the ignition of the gas generator (replacing the spark plug).
Clean or replace the air filter.
You can also check the tightness with which the valve is seated. In the simplest case, you need to unscrew the cover of the block head (when the outlet and inlet pipes are not screwed to it).
Check if the valve timing and ignition timing are set correctly. It can go astray from the working vibrations of the unit - the locking bolt that fixes the magneto is gradually unscrewed.
When the engine of the unit does not start immediately, you need to arrange a small technical inspection. Check the fuel level, the oil for the gas generator, the serviceability of the candles and the filter. It is unacceptable if the candles are dirty or cracked. Replace damaged ones, clean dirty ones with a wire brush. Remember that the generator must be cooled normally; when overheated, the power unit often fails.
If the voltage is completely absent, it is necessary to disassemble the gas generator and inspect it. In this case, several points can serve as the cause of the problem: lack of contact, malfunction of the brushes, burnout of the PWM unit, capacitors, etc. When the motor speed is stable, but the voltage constantly jumps, then the excitation regulator is most likely damaged.
Before you change a burned out block, you will need to find the exact cause of its failure.
Do-it-yourself minor repairs of gas generators, most often, are needed when candles, an air filter fail, there is no fuel and oil. Without them, most models simply will not start, as the built-in protection is triggered. Constantly monitor the condition of the mesh at the fuel filter and the cleanliness of the air filter.
A missing ignition spark can also be the cause of the problem. To solve it, unscrew the candle with a special key, clean the soot with an emery cloth and an iron brush, wipe it well with alcohol and dry it. Then check for spark and start the unit. Please note that carbon deposits are deposited if low-quality gasoline is used, and also when the fuel does not burn completely.
You may still need to adjust the carburetor.Soot often occurs due to the fact that the generator is operating at partial power. Major issues are best left to the experts. If you do not have sufficient skills, it is better not to try to correct them. We carry out repair of gas generators of any modifications.
There are two main types of generators: industrial and domestic. They have different power, dimensions, fuel costs and so on. The principle of operation is identical. Main differences:
The household model does not have a large resource, therefore it is intended only for short-term use. Power does not exceed 2-3 kW. They produce a single-phase current of 220 V.
Industrial models are designed to run smoothly for a long time. The power can be incredibly high, depending on the system being served. They produce a three-phase current of 380 V.
When buying, the choice should be based on the conditions in which the equipment will be operated. It is important to understand that a homemade gas generator is not as efficient as a model from the manufacturer.
The main mechanism is a gasoline engine, the principles of operation of a gasoline generator are based on it. Currently, two-stroke and four-stroke versions are used. The first type has a simple design, is lighter and cheaper, but it has a minimal resource and is not intended for long-term use, although it is usually suitable for home purposes. But more often choose four-stroke models, they fulfill their purpose in full.

The generator is the main working unit of the equipment that generates electric current. When the rotor moves, the current is excited on the stationary stator, due to the alternating magnetic field. In fact, the presented aspects of physical strength and theory are not of great importance. To eliminate the malfunction, it is enough to change some parts, since they cannot be repaired, but only replaced. You may need a gas generator electrical circuit, where you can more thoroughly study the main aspects. There are differences in power:
Low-power power plants with indicators up to 2 kW. Used for short run. Most often they serve small refrigerators or to illuminate the territory with several light bulbs.
Medium type models with power up to 6.5 kW. The equipment is used to provide electric current to small houses, garages or shops. These are professional systems that work exclusively on gasoline engines.
Powerful electric generator up to 15 kW. Unique systems where not only a gasoline engine, but also a diesel engine can be used, it all depends on the manufacturer. All models are only three-phase and are used to supply power to huge buildings, enterprises or industrial facilities.
Consumers have the opportunity to replace a generator or engine in any segment, but this should be done only after considering all further technical indicators in advance. That is, it is possible to make one out of two gas generators if some parts are damaged and unsuitable for further operation.

Gasoline engines are installed on generators most often, of course, there are models that run on diesel fuel, gas, but they are less popular. A variety of breakdowns occur during operation, and sometimes their elimination requires urgent intervention. Only in this way, it will be possible to achieve the required indicator. Considering the main types of breakdowns and defects, it all comes down to the fact that they are always identical. The design of the motors is the same, and they differ only in technical characteristics, so it will be much easier to eliminate engine breakdowns than a generator. Main faults:
The engine does not start. There is no fuel or a spark on the candles, the integrity of the crank mechanism is broken. There are defects or foreign elements preventing this.
The operation of the equipment is uneven with interruptions. The fuel has foreign impurities, the operation of the spark plugs is disrupted.
Breakdowns associated with the crank mechanism. Most often, this leads to the fact that there is a fuel supply, as well as a spark, but the engine does not start. There may be no compression due to worn rings.
Sometimes pistons break on Chinese models, as low-grade metal is used.
Poor quality oil can also cause clogging of the channels, which will lead to overheating of the motor.
Carburetor clogging occurs due to poor-quality fuel, foreign impurities, or prolonged non-use of equipment.
Technical issues are resolved only through specialized service stations. If there is a guarantee and service in the city, then the choice is completely obvious. In this situation, nothing can be disassembled, since specialists will refuse free repairs, due to a violation of the integrity of the structure. Therefore, you need to check the warranty period first.
The equipment has many different additional parts and mechanisms that perform their technical tasks. The installed inverter muffler is part of the sound insulation. When using a gas generator, a large amount of noise is emitted, so it must be minimized. Developers are trying their best to create better systems for these devices.
Regarding the presented aspect of the repair work, it is recommended to contact specialized service stations. You can buy a new generator for a gas generator and install it yourself, otherwise you can’t do without the help of specialists. The main types of breakdowns and methods of elimination:
The generator does not produce electricity or works intermittently. Violation of the integrity of the electrical circuit, the winding is damaged, the motor does not transmit torque.
There was a burning smell. The generator burned out, there was a short circuit.
In case of any type of violation, it is recommended to immediately turn off the engine. Next, an external inspection is carried out or a master is called. The second option will be more rational and efficient.
A starter is required to start the engine. Most often, manual is used, but more powerful models are equipped with electric starters like automobile ones. Repair and maintenance of these technical elements is carried out by complete replacement. The problem is that most of them are non-repairable. Standard disassembly can lead to the fact that you simply cannot put everything back together.
The main condition for carrying out repair work is to refer first of all to technical aids. This will allow you to deal with all breakdowns and other restrictions in advance. Your hand will become the main assistant in carrying out repairs and maintenance. Checking of electronic units is carried out using specialized stands. That is, it is computer software that will allow you to identify all the shortcomings of the equipment in the early stages.
Regardless of type or brand, all gasoline generators are serviced identically. For the convenience of consumers, special manuals and recommendations are attached to the equipment, so as not to forget about the planned maintenance. You should always start with an external inspection so as not to miss damage to external parts. Of course, if you have a Chinese inverter generator, then you may have problems finding components. The main types of work included in TO:
The inspection should consist of viewing all work items.
It is necessary to remove the air, fuel filter and replace with a new one. The term of the change depends on the duration and regularity of use of the equipment.
It is recommended to replace belts, candles.
A standard off-grid generator needs regular oil changes.
Based on the presented aspects, it will be possible to increase the service life of equipment to the maximum.
You can replace the wheel on mobile equipment without any special problems.
It is recommended to pay attention to Fubag equipment, this is a German brand that produces a new generation of electric generators. This option will be able to fully satisfy all the individual wishes of customers. The company produces various types of equipment models, with different technical characteristics. That is why you can easily pick up everything you need without any restrictions.
Of course, in order to properly carry out maintenance and repairs, you need to know the device of the gas generator, then you can not only change parts, but also assemble it back. This is not so easy to do, since there are a large number of various nuances that are recommended to be studied at the preliminary stage.
Any equipment requires professional care. Therefore, it is recommended to adhere to the rules that the manufacturer provides customers. These are very important aspects that will not only improve the start-up of equipment, but also increase the overhaul period. Key recommendations:
For long-term storage, be sure to drain all the fuel from the tank. Gasoline oxidizes carburetor parts, which can lead to clogged passages.
It is recommended to use polyethylene to cover the equipment during long-term storage, to protect against corrosion and moisture ingress.
It is best to carry out maintenance before storage.
In no case should the generator be left disassembled for a long time, as foreign elements may get inside.
Store in a dry and cool place.
Do not start equipment in severe frost unless it is designed to operate in such conditions.
Thus, you can protect not only your money, but also your equipment. Currently, manufacturing companies provide customers with special technical instructions that go into all the details in detail.
