Do-it-yourself VAZ 21053 carburetor repair video

Design nuances

To obtain the above engine characteristics, the manufacturer carried out experiments:

• piston stroke reduced to 66 mm;
• the cylinder diameter, on the contrary, is increased to 79 mm.

The result was a revving, powerful engine with an aluminum valve cover that absorbed the sounds of the drive. Another feature of the internal combustion engine is the fastening of the timing belt pulley - users do not need to unscrew the bolt on the crankshaft, unlike previous VAZ engine models.

Design 2105

In the operating instructions, the manufacturer recommends which oil to pour into the engine - 5W30 - 15W40.

Carburetor adjustment

The carburetor adjustment process will improve engine performance and extend its service life.

Therefore, it is so important to carry it out more often, without waiting until obvious signs of a malfunction appear, for example, failures in engine operation or a distinct smell of gasoline in the cabin.

A few preliminary steps that will help facilitate and optimize your work:

Before you start setting up, you need to remove the mechanism, wash and blow it out. Prepare tools: a set of wrenches, Phillips and flathead screwdrivers

It is also important to find the instructions for the VAZ 2105 so that all the necessary characteristics are before your eyes

When everything is ready, you can proceed directly to the setup. Of all the systems that make up the carburetor, only the following are subject to adjustment:

• Device launch system;
• Idle move;
• Maintaining the level of the fuel mixture (related to setting the float mechanism);
• CO2 level.

Next, we will consider all stages in more detail.

Setting the float mechanism

Before tuning, you should let the car idle. Once you have done this, proceed to the next steps:

1. Remove the cover from the carburetor.
2. Check the fuel fluid level (the value should be 28 mm).

If a different indicator is detected, the float mechanism must be adjusted. For this:

1. We place the lid vertically so that the fitting through which the fuel is supplied faces upward. The float tongue should be perpendicular to the axis of the needle valve. If you have different indicators, bend it with pliers.
2. The distance from the float to the cardboard spacer is 6-7 mm. Otherwise, we bend the bracket on which the float is held to the required values.
3. After adjusting the mechanism is completed, return the cover back.

Adjusting the starter

To configure the device, do the following:

Close the choke (for convenience, secure with a paper clip)

Pay attention to how the telescopic rod is installed. Pull the thrust lever with your finger until it stops.

We measure the gap of the slightly open upper flap. Standard – 5 mm along the bottom slot. For convenience, you can measure with a drill of a suitable size. If the value does not correspond to the specified one, then set the required gap by rotating a special adjusting screw located on the generator starting device.

Idle speed adjustment

Adjustment is necessary when idle speed disappears

It is important not to make mistakes here, so you cannot repair the mechanism without knowing its structure or at least first reading the instructions. What do you need for this?

1. Unscrew the quality screw (three or three and a half turns). Turn the quantity screw back six to seven turns.
2. We start the engine. Reduce crankshaft speed if it is too high.
3. After the engine has warmed up, set the tachometer to 900 rpm, turning the quantitative screw.
4. Ten minutes later we turn off the car. Checking the spark plug electrodes. If there is no soot, the setting is successful.
5. If soot appears, clean the electrodes and tighten the quality screw 0.5 - 1 turn. Next, we repeat the previous steps until the soot on the candles disappears.

Change in co2 content

To change the carbon content, you need to crank the wine quality. First screw it all the way, and then unscrew it four to five turns.

VAZ-2105: a real breakthrough!

We can consider such a case using the example of the VAZ-2105 power unit, because it made a very significant breakthrough among its colleagues in the workshop. The fact is that before it, all models used a belt drive for the gas distribution mechanism. Its predecessors used a chain, which resulted in an unpleasant noise. But since the 80s this has changed. The domestic auto industry borrowed the idea of ​​using a gas distribution engine from the Ford Pinto. No one wanted to use such a system, since during intensive work a belt break was more likely than a chain break.

But the structural features of this mechanism made it possible to avoid an unpleasant incident, which would not only be very dangerous on the road, but would also cost a very expensive repair. Opposite each of the valves there are special holes that are located on the working pistons.

Tuning the body and Solex carburetor

It is no secret for all VAZ 21053 car owners that their cars, manufactured back in Soviet times, are not distinguished by comfort, quality and proper appearance. For many old domestic cars of the VAZ 21053 brand, which have survived trips on Russian “high-quality” roads and have lost their attractive appearance and gloss over time, body tuning done by yourself is especially relevant.

The modernized engines urgently need tuning of the Solex carburetor, since they are compared to the standard analogues of the sample at 4000 rpm. and higher can get a higher filling coefficient, which in turn will reach about 1.35-1.5, which may well cause increased air consumption, and the maximum speed will exceed 6000. The Solex carburetor has in its arsenal a diffuser diameter of 24/ 27, its advantage is that it has an increased mixing chamber in addition to the diameter of the diffuser, which enabled the manufacturer to install a throttle valve with a diameter of 34 mm.

Many owners prefer to update the old body design on their own, remove everything unnecessary and install only the best. To do this, you can remove broken and worn bumpers, hoods, trunk lids and all doors. Only the frame will remain. Wipers are removed from trunk lids, as they spoil the appearance of the car. Rivets are installed in the holes that appear where the wipers were located.

Then the doors are tuned. It is necessary to remove the inner lining and cover the doors with soundproofing material, after first removing the handles from them. Cover all treated areas with putty. It is better to purchase a new, more improved hood, since if you repair it yourself, it will take a lot of time, effort, and is very troublesome.

After the proper procedures have been carried out, all removed elements are returned to their original places, topcoat and base paints are applied to the body, and after drying, a transparent varnish is applied on top of them. Now the most important work begins: a beautiful aerodynamic body kit is installed efficiently and smoothly, radiator grilles, mirrors and headlights are replaced, and new wheels are installed on the wheels.

What cars were equipped with ICE 2105?

This modernization could not satisfy users of the domestic automobile industry. The main drawback was the regular breakage of the timing belt, AvtoAZ management reduced production volumes, then removed the 2105 engine from production, so only three modifications of the Zhiguli were equipped with the engine:

• 2105 sedan;
• 2104 station wagon;
• 21072 sedan.

Four with engine 2105

Currently, tuning for the engine of this series is not difficult, but among the operating fleet of Zhiguli “fives” with the “native” engine there are very few left.

Tuning

Recently, the “stens” movement has become increasingly popular. So, the owners tune the VAZ-21053 by installing:

• Classic alloy wheels with a wide shelf.
• Arch extensions.
• JDM style mirrors (placed on the hood).
• “Lips” in the front of the car.
• Spoiler in ducktail style.

The reader can see what the Soviet “five” looks like after this tuning in the photo below.

This car really attracts attention.

Pros and cons

Subject to compliance with maintenance and operation regimes, major repairs were not required for the machines for decades. In capable hands, the 2105 engine produced in 1989 is still in use today, and the timing belt life is enough for 40,000 km. If there are no problems with consumables, then the demand for spare parts is not fully satisfied. For example, the cylinder head is always available, and the intake manifolds are welded on site.

VAZ-21053: photo and description, technical characteristics, tuning

Perhaps the most famous car from the USSR is the Zhiguli. So many of them were produced that even now they are often found in cities. One of the popular models of the “Classics” family is the VAZ-21053. The common people called the car “five” (by analogy with the “troika”, “four” and other VAZ cars). What is the VAZ-21053? Specifications, photos and reviews are further in our article.

Correct use of the vehicle

This model has a soft suspension. It is able to dampen vibrations even at high speeds. However, sharp blows should not be allowed. They can lead to deformation of the axles of the lower arms. Due to constant increased vibration, other parts of the chassis wear out quickly. You also need to ensure that the car is not subjected to unnecessary loads. The weight of cargo that can be transported in the trunk and on the roof should not exceed 50 kg. It should be noted that the operation of a VAZ 21053 car is very similar to the use of the 5th model.

Maintenance regulations

Knowing what kind of oil is used in the engine and the type of liquid with which the cooling system is filled, you can carry out maintenance of the “five” internal combustion engine yourself.

Procedure for adjusting DAAZ 2107-1107010-20

Adjustment is carried out only on a serviceable and serviced carburetor. It is highly desirable to have a device that can measure harmful CO emissions. Let's look at the procedure:

• We check the level in the float chamber. This is done using a template, which you can make yourself or purchase at a specialized store.
• We check the gaps of the contact group of the ignition distributor (look in the technical book of your car) and visually inspect the spark plugs. The latter must strictly correspond to the engine model according to the heat rating.
• We start the engine and let it warm up to operating temperature.
• We use a screwdriver to adjust the screw for the amount of combustible mixture. With its help, you should set the speed within 820-900 rpm. We control their number using a tachometer (built-in or separate).

We tighten the fuel mixture quality screw. At the same time, it is important to monitor the amount of CO in the exhaust gases (a working engine at a temperature of 20 degrees Celsius produces 0.5-1.2% CO). Use the mixture quantity screw again and set the idle speed.

I thought for a long time about the Solex

for classics, I compared prices, there is DAAZ 21053-1107010-20 and PEKAR K178I.21053-1107010-20, I almost bought PEKAR, but DAAZ
suddenly dropped in price
from 3990r to 3790r, and then completely to 2990r

so what did I know about carburetors for classics with an engine capacity of 1.5-1.6:

1) for classics (2105, 2107, 2104) with an engine volume of 1.5-, 1.6, a SOLEKS type carburetor is intended 21053-1107010-20

- no options! (no 083 - catch the crap, catch it, catch it!)

2) consumption with a SOLEKS carburetor compared to a standard carburetor 2107-1107010 will be MORE!

, the car is more responsive, but you have to pay for everything - on average 0.5 liters more per 100 km

I didn’t install it myself - I installed it without an economizer, I don’t know yet whether it’s better or not

I recommend

to watch the blog of carburetor engineer from Dmitrovograd
Nail Poroshina
- very interesting! Video blog of Nail Poroshin (Dmitrovograd)

so that Solex doesn't get dirty

(they have such a disadvantage) you can install a mesh and not have any problems at all, as well as a cut 4th “cam from Nail”

1) the car has become a little faster2) you need to warm up less to get moving3) yes, the car is responsive! (smooth ride when changing gears) 4) even the consumption seemed to decrease, even without an economizer - I think the standard carb was a little clogged and ate gasoline very well

and the result: an injection engine is not needed, Solex-a 21053-20 is enough for the ears

I recommend installation!

continuation of a story

I drove for a day, I looked at the idle speed of 1000 somewhere, turned it up to 750, and the next day the idle speed disappeared altogether, as soon as the car stopped at the intersection... I turned it back up... but the idle speed floated 850-1200, so I drive (it was decided - the plug flew out in manifold, plugged it in with a new one and carefully set the speed with the screw - everything was fine)

PLEASE COMMENT on the installation, how should it be done?

Issue price: 3,500 ₽

Causes of malfunctions and their elimination

In principle, the 2105 engine has all the typical malfunctions of carburetor in-line internal combustion engines:

• clogging of the fuel system, fuel pump, carburetor, throttle, jets and filter;
• exhaustion of the life of the air filter and microswitch;
• failure of the ignition system and stuck valves and piston rings;
• breakdown of gaskets and seals, misadjustment of cam gaps;
• production of cylinders/pistons, bearing shells;
• loosening the flywheel bolts and attachment drive belts.

Engine faults 2105

Cons of the 2105 engine... the 2105 engine still requires valve adjustment. In addition, the 2105 engine stalls, this may be caused by the thickened oil in the box not being warmed up. Just warm up the car in the cold season and only then start driving.

A knock in the VAZ 2105 engine indicates that the valves are not adjusted, go to a mechanic or adjust them yourself differently with an increase in the thermal gap, in addition to additional noise, you will experience a decrease in the already not high power, valve burnout, camshaft imbalance, increased consumption fuel, etc. In general, the VAZ 2105 engine malfunctions are completely identical to the 2101.

Why are modifications difficult?

Increasing the power of a belt-driven motor is much more difficult. For example, when using a humped camshaft, you have to install a split gear. For a 5 engine, it simply does not exist with a belt, that is, you will not be able to set marks. In this case, it is better to change the entire engine or install a conversion kit on the injector.

It is reasonable to carry out deep tuning of the VAZ 21053 engine only for certain creative reasons. Simple modifications to the machine with your own hands can be done without significant financial costs.

For example, if a car engine gets very hot, you can upgrade the power system. At the same time, you will be able to achieve reduced fuel consumption.

Before starting work, you should carefully study the recommendations of professionals and draw up an approximate tuning budget, as well as create an estimate of parts. It is important to determine where the parts are marked and where the marks are. Quite often it turns out that the accumulated money is not enough. Everyone should understand why this happens. When disassembling a vehicle, it usually turns out that it is necessary not only to modify the engine, but also to overhaul the main parts of the body. Also, before performing work, get a diagram or repair book. Regardless of the fact that the markings may be different for different units, you can use the literature for different Zhiguli models.

Injection instructions 2105

If we compare the three mechanisms, the last one ranks last both in terms of popularity and power. VAZ 21054 is no exception. First, let's look at the main complex of this mechanism: an autonomous idle system, a float chamber, a valve to close the idle speed, an econostat, a system used for dosing, a throttle valve, a compartment for removing gases from the crankcases and a transition system for both gases. This seemingly very small amount of information is already enough for you to start cleaning and adjusting the VAZ 2105 yourself.

It is after cleaning the carburetor that adjustment occurs. But you need to remember that you shouldn’t look for breakdowns where there are none. In order to correctly and well adjust the VAZ 21054 carburetor, you need to very carefully consider and remember all the contents of the mechanism. It is important to clean all parts from dust and foreign bodies. It is also necessary to wash the float chamber and clean the strainer. Having completed all of the above, proceed to cleaning the air jets and adjusting the system for the floats, trigger and idle speed.

The strainer is an important part of the carburetor and needs to be checked from time to time. As a rule, the check is carried out every 60,000 revolutions. To check the strainer, you need to use manual fuel supply and fill the float chamber with fuel. After closing the valve, you need to slide the top part of the filter and remove it.

About setup

Maintaining the required fuel level in the carburetor is ensured by a special float mechanism.

Float mechanism

To set it up, you need to start the engine and let it idle for a few minutes. Then you need to remove the carburetor cover and check the fuel level in the float chamber - it should be 28 mm.

If it is different, you need to do the following:

1. Measure and adjust the distance between the cover gasket and the float when the float and the needle valve ball are in contact. It should be equal to 6.5 mm (0.25 mm deviation is allowed).
2. We make adjustments by bending the tongue.
3. We check the maximum stroke of the valve needle, which should be 8 mm. To check, measure the distance between the cover gasket and the float at its maximum extension. It should be equal to 14 mm with a deviation of 0.5 mm. To eliminate the deviation, you need to act on the bracket.
4. Visually check the perpendicularity of the tongue relative to the axis of the needle valve, as well as the parallelism of the float relative to the bottom cover. If you notice any irregularities, straighten everything out.

If after all the above steps you are unable to achieve a stable fuel level of 28 mm, the needle valve in the float chamber should be changed.

Starting device

To adjust the starting device of the VAZ 2105 carburetor, you need to do the following:

1. Use the thrust handle, which is located in the cabin, to close the air damper.
2. Make sure that the rod shank is at the end of the carburetor trigger rod groove. If there is a violation, correct the situation by bending the rod.
3. Remove the cover and measure the gap between the edge of the damper and the chamber wall with the rod recessed. It should vary from 5 to 5.5 mm. We adjust it by rotating the adjusting screw of the starting device.

Idling

To adjust the idle speed, you need to start and warm up the engine, and then perform the following operations:

• Turn the engine to 850 rpm by turning the mixture quantity screw.
• Use the mixture quality screw to bring the speed to the maximum level.
• Reduce the speed to 850 using the quantity screw.
• Maximize the quality screw.
• Having achieved 850 rpm, tighten the quality screw until the engine shakes.
• By unscrewing the quality screw, ensure stable operation of the motor.

With proper adjustment of the carburetor of the five, fuel consumption in summer should not exceed the following indicators:

• 7-7.5 liters per hundred outside the city at a speed of 90 km/h;
• 8.5-9 liters in city mode.

If you cannot adjust and repair the carburetor yourself, do not torture yourself or the car, but contact a specialist.
