Dimensions of the VAZ 2107 car and other characteristics

Production of the legendary seven at the Volzhsky Automobile Plant began in March 1982 and continued for more than 30 years. The car still enjoys well-deserved popularity in our country and abroad. The dimensions of the car allow it to be classified as class B according to the international standard or group 2 according to the national standard. VAZ 2107 is currently being assembled at Izhmash and in the Chechen Republic.

The Seven was exported under the name Lada 1500, Riva or Nova. It is an improved luxury version of the 2105 model. A number of changes were made to the design of the prototype, in particular the electrical circuit, attachments and the engine itself were changed. The VAZ 2107 has an improved interior; the front row has seats with integrated headrests.

Geometric parameters of the car

The car has a monocoque three-volume sedan-type body in the classic version. The engine compartment is located in the front part, the closed passenger compartment is in the middle, and the trunk is located at the rear. There are 4 doors for the driver and passengers to enter; the engine compartment is closed by a hood that rises forward. This scheme has become most widespread in the automotive industry as the most successful.

The table of dimensions of the VAZ 2107 car is given in the technical documentation; the main parameters are:

A detailed diagram with precise indication of linear dimensions is indicated in the official publication of the vehicle operating instructions.

Machine weight characteristics

For its time, the VAZ 2107 was an excellent car that was successfully sold, including outside our country. The machine's technical characteristics were not inferior to its analogues at a lower price; the design scheme used is highly reliable. The weight of the equipped vehicle is just over a ton, which allows it to demonstrate good power capacity.

The maximum permissible load is 400 kg, in other words the car can carry five adult passengers. If the quantity is smaller, luggage can be transported in a special compartment. A rational distribution of masses between the axles ensures good stability and controllability of the vehicle.

The small dimensions of the VAZ 2107 model, optimal weight for its size and a powerful engine provide the car with good dynamics and maneuverability. The successful design and low price predetermined the car's commercial success and, despite its advanced age, it still does not lose popularity.

Features of operation and maintenance

• Fuel selection

It was said earlier that many drivers cannot decide on the type of fuel used for their engine on the VAZ 2107. And if with AI-92 everything is simple, since its composition is very similar to AI-93, then with AI-95 everything is not so smooth.

Increasing the octane number leads to an increased risk of valve burnout, but gives a small increase in power. The engine begins to run smoother and more stable.

But the designers still took into account the possibility of using AI-95 gasoline. You just need to correctly set the ignition timing on your car (if you have a conventional carburetor engine) or reflash the engine control unit (if your VAZ 2107 engine is fuel-injected). But usually even this is not required. Engines of this brand are very durable and not picky about the type of fuel (within reasonable measures).

• Change of oil

Changing the oil on any engine must be approached with the utmost seriousness. Poor quality oil can lead to not very pleasant consequences, such as accelerated wear of main components and assemblies.

The ability to select oil is a real skill. Taking well-known brands is not always safe, since you are very likely to come across a counterfeit from dishonest companies. At best, you will not receive the positive qualities that this company has. At worst, you will have to carry out major repairs.

You shouldn't buy unknown brands either. In this case, you are buying a pig in a poke. You can buy oil that is of a quality that is not inferior to expensive analogues, or you can end up with expensive repairs. It is best to buy oil in specialized stores, where you can get at least some explanation and compensation.

Another important parameter is the oil class according to the international nomenclature. True, everything is simpler here. You just need to take the oil that the manufacturer himself recommends.

The manufacturer (AvtoVAZ) for VAZ 2107 engines and other models with this type of engine recommends:

• 5W-30;
• 5W-40;
• 10W-40;
• 15W-40.

You need to take about 4 liters of oil. When changing 3.5 liters of oil is usually enough. It’s better to carry the rest with you in the trunk, since oil consumption in this engine leaves much to be desired.

• Changing the oil in the VAZ 2107 engine

The procedure itself is quite simple and should not raise any questions. It is better to change the oil on a VAZ 2107 in the warm season.

1. First you need to start the car and warm it up to operating temperature. Then turn it off and let the oil fall back into the crankcase. This will take about half an hour. During this time, we prepare a receiving container with a volume of 4-5 liters, as well as new oil, a watering can and a hose.
2. Use a special wrench to unscrew the plug on the crankcase and wait for the old oil to drain out.
3. If you change the type of oil or brand, you must also take flushing oil, which will clean the engine of the remnants of the old one. We pour it in the same way.
4. Then we tighten the crankcase cover and fill in new oil through the neck on the cylinder head. We measure the level with a dipstick. It should be somewhere between the MIN and MAX marks. Please note that oil is not water and it cannot quickly sink into the crankcase, and therefore after a short stop the oil level in the crankcase will rise a little more.

Usually, along with changing the oil, the oil filter is also changed. It's even simpler here:

1. We unscrew the old one using a special tool (you can also use an ordinary rope), lubricate the o-ring of the new filter with oil and screw it in place of the old one.

• Adjustment of valves

Adjusting valves is a rather complicated process and requires certain skills and tools. Actually, it is advisable to entrust the valve adjustment itself to competent specialists, but if you want to do everything yourself, then this video is for you:

Major repairs and maintenance

If valve adjustment can be done at home, then major engine repairs should only be entrusted to specialists.

During a major overhaul, all components and assemblies of the VAZ 2107 engine are checked for serviceability. They will check for you:

1. Valve condition, adjustment;
2. Chain, chain tension;
3. Condition of oil seals, valve stem seals;
4. Geometry of the cylinder block;
5. Condition of the pistons, crankshaft, pins, connecting rods;
6. Wear of compression rings;
7. Condition of the oil pump and coolant pump.

If damaged, the part will be replaced. The cylinder block will be bored out, which will increase the combustion chamber and working volume. After this procedure, the car will be run-in for several thousand kilometers.

Typically, running-in lasts 5-10 thousand km. At this time, it is not advisable to give the engine heavy loads. After completing this procedure, your engine will make you happy.

Malfunctions

1. Engine won't start

2. Knock of the crankshaft main bearings.
Usually a dull, metallic knock. It is detected when the throttle valves are opened sharply at idle. Its frequency increases with increasing crankshaft speed. Excessive axial clearance of the crankshaft causes a sharper knock with uneven intervals, especially noticeable with a gradual increase and decrease in the crankshaft speed.

Engine tuning

The most popular types of tuning for engines of this type are increasing the displacement, replacing the camshaft, installing a zero-resistance filter and direct-flow exhaust.

The most effective way (and the most expensive) is to install a turbo kit.

• Increase in working volume

The design of the VAZ 2103 engine allows for a good increase in displacement, since its cylinder block is almost identical to the VAZ 2106 engine block. And when this block is bored, it can be made to fit the piston and rings of the VAZ 2106 engine.

Thus, we get an increase in displacement, which increases fuel consumption and power. If even this is not enough, then they sharpen the pistons on the valve side and install a crankshaft from the Niva, which also increases the working volume. Presumably after these operations you can get an engine with a displacement of 1.7 liters, sometimes 1.8 liters.

• Installing a new camshaft

This modification does not increase engine power, but changes the nature of its operation. In most cases, they try to install a camshaft that will transfer maximum torque to as low a speed as possible. This makes the engine more responsive at lower speeds, which has a very good effect when driving at low engine speeds. The best option for such a modification is a camshaft from Niva 21213.

• Installation of direct-flow exhaust and zero-resistance filter

The most popular modification. First of all, it's pretty cheap. Secondly, it allows the car owner to show off to neighbors in the garages. In fact, it does not have any practical benefit for the stock engine. Allows you to feel a slight increase in power only at high speeds.

It is quite effective when installing Turbo, since it does not put pressure on the engine, which is now capable of developing enormous power. Direct-flow exhaust is not convenient due to increased exhaust sound. It is dangerous to use the filter in wet weather, as it can let water into the engine, causing water hammer.

• Installation of turbocharging

The most expensive and effective way to increase engine power, while its resource sharply drops by 2-3, sometimes 4-5 times.

Requires deep exhaust tuning:

1. Installing T-Valves
2. Imported rings and forged pistons
3. Lightened crank feces
4. Intercooler and much more.

It is also necessary that your VAZ 2107 engine be fuel-injected. The carburetor can simply burst due to such high pressure. This article will not describe the procedure for installing Turbo on a VAZ 2107. There is enough such information on the World Wide Web. Here we will simply indicate a price of approximately 15% of the cost of the car. If you are ready to spend your money on this, go for it.

Salon "VAZ-2107"

The “Seven” was created on the basis of the “VAZ-2105”. It was a modified luxury version of the Five, aimed at wealthy people. People called it the Russian “Mercedes”. The interior of the car was luxurious for those times. Inside, there were seats with integrated headrests and a special dashboard that notifies you about the speed, fuel and oil levels, and engine heating temperature. The heating system has also been modernized. It directed air flows not only to the windows, but also to the driver’s feet.

Modern drivers won’t be surprised by the 7’s interior or trim levels. The car has no airbags, not to mention ABS and other electronic assistants. In the “top” versions you can adjust the angle of the headlights and headrests. For 10-15 thousand rubles, the equipment can be supplemented with multimedia, tinting and alloy wheels.

The cabin is comfortable for four passengers of average build; it will be a bit cramped with a fifth in the back seat. The trunk holds 379 liters of cargo. You can’t hide large luggage there - there’s enough space for several bags of groceries from the supermarket and a bag with tools.
