Removing, checking and installing the VAZ 2107 starter (injector, carburetor)

Every person who knows even a little about cars knows perfectly well what a starter is and what it is needed for. To briefly describe its purpose, it is necessary in order to start the engine. It is a DC electric motor, which has quite a lot of power. Of course, every component and unit in a car tends to become unusable, and the starter is no exception. This means that at some point you will have to start repairing it. This article will discuss how to remove and install the starter on a VAZ 2107 yourself. Separately, it is worth noting that this car, as a rule, has an injection power system, but you can also find a carburetor “seven”.

If you do everything yourself and with high quality, you can save a lot. The main thing is to approach the procedure with full responsibility, because there will be no one to blame if something happens.

Dismantling process

Removing the starter on a VAZ 2107 begins with the fact that you need to detect it. This point concerns beginners, because experienced drivers know where the starter is located. Located near the bottom of the power unit. It will not be possible to remove it while on the ground. You need to drive the car either into a pit or onto an overpass. In fact, awkward placement is the biggest problem in the removal and installation process. Otherwise, everything is very simple and convenient.

The actual dismantling process is as follows:

1. First of all, you need to remove the battery terminals. 2. Some 7 models have a mudguard, it is installed under the engine. It needs to be dismantled. 3. Remove the battery. 4. Unscrew the clamp of the wiring harness going to the starter. 5. Remove the wires from the traction relay. 6. Remove the stretch marks that come from the inlet pipeline. 7. The starter itself is removed.

The dismantling process is completed, and now you can take the starter for repairs, or replace it with a new one.

The above describes the process that is performed on cars with an injection power system. Do not forget that there are VAZ 2107 models with a carburetor installed. In such cars, the dismantling process has minor differences. The carburetor model does not have an intake pipe or stretch marks from it. This means you need to do this:

— Remove the wires from the traction relay. — Remove the air duct and the air filter. — Remove the starter.

Actually, the difference from the injector is only in one point, as you can see. As for the malfunctions that may occur, most often drivers are faced with the fact that the starter does not turn. In this case, it is better to install a new one, but you can send the old one for repairs, in the hope that a good repairman will come across who can fix everything.

Preparation for repair and dismantling of the device

The starter unit on domestic “sevens” is a four-lane electric motor equipped with four currents. This unit is a DC motor. If it breaks, the crankshaft of the power unit will not be able to turn when trying to start the engine.

Regardless of the device model, the unit is mounted in the engine compartment. The starter mechanism can be seen to the right of the cylinder block of the power unit. It is fixed in the seat using three screws and mounted on the clutch system housing.

It is more convenient to carry out work in a specially equipped room - a garage box. The VAZ 2107 is installed above the inspection hole; for repair and restoration operations, a set of wrenches, a set of heads with a wrench and a device for pressing out the bearing are required. In the event of a malfunction of several other components in addition to the bendix, it makes sense to replace the starter assembly. On a car where there is an injector in the power supply system, repair work is best carried out from below.

The procedure for dismantling the starter on a VAZ 2107 car is as follows:

Disconnect the battery and remove it from the engine compartment.
We unscrew the terminal and disconnect the terminal and the wire that supplies power to the starter.
We unscrew the bolts securing the device that ensures engine starting.
We remove the unit complete with the bendix feed mechanism from the hole in the housing.

On a VAZ 2107 car, an engine with an injector installed will require a number of additional operations. In this case, replacing the faulty unit is only possible from below. To gain access to the assembly, you need to remove the steel protection and boots covering the engine compartment from below. The remaining operations carried out on the starter are carried out similarly to those described.

Detailed installation process

In order to correctly install the starter, you must adhere to the following points:

1. Conduct a visual inspection of the device. 2. Installation of the device in its original place. First fasten with a long bolt, and then with two short ones. 3. Install the wire terminals and tighten the nuts. 4. Replace the battery. 5. Connect the terminals on the battery. 6. Install the braces coming from the intake pipe or air duct and air filter. 7. Replace the mudguard (if equipped).

After everything is done, you should start the engine. If everything works as expected, then the starter connection is made correctly. If the engine does not start, you should look for where the error was made.

Helpful information

Of course, every driver wants his car to be the best. Often, due to the fact that the design of some individual parts is already outdated, this cannot be achieved. This also applies to the starter on the “seven”, which is already quite old. To correct this oversight, some people prefer to install a gear starter. What is his task?

It is designed to transmit rotation of the starter shaft to the flywheel through a gearbox. This method makes it possible to reduce the weight of the starter several times, and at the same time increase the starting torque by almost half. It is easy to guess that in this case the starter will work much longer.

All that remains is to purchase it and install it, the result will be visible from the first turn of the ignition key. The car will start like never before.

VAZ 2107 starter repair

The starter is not the most complex and expensive unit to maintain. But it is one of the key components of the car.

You turn the ignition key, the lights on the dashboard are on, but the starter does not turn, the engine does not start? There are two reasons:

faulty contact supplying current to the starter relay;
The starter itself or the relay is faulty.

In the second case, the starter must be removed, checked, repaired and reinstalled. The repair process is quite complex and deserves a large separate article. Here we will tell you how to replace the VAZ 2107 starter (carburetor, injector) and check its performance.

Electric starter repair

Methods for restoring device functionality depend on the nature of the malfunction. The easiest way to deal with burnt contacts on the solenoid relay is to sand them with fine sandpaper. The slip rings are also cleaned and polished when replacing brushes. Other faults are eliminated by replacing failed parts or assemblies.

Removing the VAZ 2107 starter

In the "seven", as in most cars, the starter is located at the bottom of the engine near the gearbox. Work to replace the starter must be carried out on a pit or a lift in order to have free access to the mounting bolts and power supply terminals. Actually, the only problem when dismantling/installing the starter is its inconvenient location. The work does not require special tools or training.

It is necessary to remove the VAZ 2107 starter (injector, carburetor) with the battery disconnected. Otherwise, the “positive” wire running from the battery to the traction relay contact may cause a short circuit. Dismantling work is carried out in the following order:

Disconnect the battery terminals (you can remove the battery, it will be easier to work without it).

This is interesting: How to adjust the carburetor on a VAZ 2109

Remove the dirt shield if it is installed at the bottom of the engine compartment.

Unscrew the fastenings of the wiring harness that go to the starter.

Unscrew the nuts and disconnect the control and power wires from the traction relay.

Unscrew the two upper and one lower fastening bolts (One of the upper ones is located extremely inconveniently, so some “masters” do not put it in place after unscrewing it. This weakens the fastening and can lead to breakage under conditions of dynamic loads and vibrations on the unit) .

Remove the starter by lifting it down under the car.

After this, you can check the functionality of the starter and, if necessary, repair or replace it.

Conclusion

Every driver is interested in how much a regular and gear starter costs. In fact, the price is almost identical. The price of a regular one fluctuates around 3,500 rubles, and a geared one – 4,000 rubles. Considering this fact, it is of course more profitable to purchase a device that can breathe new life into the car. Considering that the installation and dismantling process will be carried out with your own hands, you will be able to save a lot.

A car starter is the main element of the engine starting system, and is designed to start it by cranking the crankshaft.

Essentially, it is a direct current electric motor driven by closing an electrical circuit by turning the ignition key. The autostarter consists of a stator, an armature (rotor), a brush holder with brushes, as well as a traction relay and a drive.

In all VAZ classic models, incl. and in the “seven”, it is located at the bottom of the engine, and is attached to the clutch housing.

Checking the VAZ 2107 starter

Before checking the starter, it is necessary to thoroughly clean it of dirt.
Then you should make sure that the traction relay is working. To do this, you need to apply “minus” to the starter housing and “50” to the terminal. A working retractor (traction) relay will push the starter gear forward, and a characteristic click will occur. If the relay is working properly, you need to check the starter windings using a multimeter. To access the winding, the brush assembly must be removed. The check is carried out in two stages:

Check for short circuit. Connect one probe to the body, and touch the winding terminals in series with the second. If the winding is not closed, the resistance must be at least 10 kOhm.
Check for a break. Connect the probes of the device to the terminals of the windings. In case of a break, the multimeter will show “infinity”.

Next you need to check the armature winding. If the armature is not closed, the resistance between the housing and the contact plates should be above 10 kOhm.

If the VAZ 2107 starter (carburetor, injector) has shorted or broken windings, it needs to be replaced. It is practically impossible to rewind the winding in a workshop.

Malfunctions

Considering that the starter is a complex electrical device, malfunctions in it can occur quite often, but most of them can be eliminated through repair. Malfunctions that cannot be repaired and require replacement of the entire assembly include:

damage to the commutator due to brush wear or other reasons;
short circuit or break in the stator winding;
short circuit or break in the armature winding;
complete wear of the armature bearing bushings.

Installation of VAZ 2107 starter

The work of installing a starter is not difficult, but it is extremely responsible. Therefore, before installation, it is necessary to carry out a visual inspection, check the equipment, make sure that the starter is working, and that the starter centering sleeve is present.

To “return” the starter to its normal place, you must perform the following operations:

Place the starter in its original place and fasten it with the longest bolt, then with a pair of shorter ones.

Install the power and control wires, tighten the terminal fastening nuts.

Screw on the starter wiring harness support.

Install the battery and connect the terminals to it.

Install (if equipped) a mudguard.

Advice: to make it easier to remove and install the VAZ 2107 starter, before starting work, you should remove the air filter on the carburetor engine or the inlet pipe stretch on the injector.

Diagnosing starter problems

After removal, it is necessary to very carefully clean the starter from any dirt adhering to it to prevent it from penetrating inside the housing. Then we begin diagnostic work. First you need to make sure that the traction relay is working properly, for which we carry out the following actions:

connect the positive terminal of the battery to the starter output, and the negative terminal to its housing;
apply a voltage of 50 volts;
If at the same time the gear of the part (the Bendix, designed to engage with the flywheel and spin it to the required speed) moves out of the housing with a characteristic click, we continue the diagnosis. Otherwise, replace the traction relay.

Further troubleshooting requires a multimeter to detect short circuits or broken wires. First, we remove the brush assembly to gain access to the winding, after which we “call” it with a measuring device. Make sure that the resistance in this case does not exceed 10 kiloohms. In addition, the multimeter should not detect “infinity” when measuring voltage - such a result will clearly indicate damage to the wires.

If a short circuit or break is detected, a new starter will need to be installed, since this part cannot be restored. Its installation is carried out as follows:

We mount the starter in place and screw it firmly in place. In this case, it is important to first use the longest fastener, and then the remaining two short ones;
install power and control wires;
screw the support that secures the starter cables;
install the battery, then connect the negative and positive terminals.

If your car has a mudguard, it is installed last.

How to remove the starter on a VAZ 2107

The starter is an integral device of any modern vehicle with an internal combustion engine. Without going into details, we can characterize the starter as an electric DC motor, which has a fairly large power and is responsible for starting the car engine. The starter, like any other part, wears out and fails over time, so sooner or later any car owner may be faced with the need to dismantle it for the purpose of further repair or replacement. Today we will talk about how to remove the starter on a VAZ 2107 in a garage without the involvement of third-party specialists. If for some reason it is not possible to carry out this work yourself, then the car can be made available to the service station workers, but in this case you must be prepared for additional financial costs.

Preliminary work

We install wheel chocks
Performing a few simple steps related to preparing the VAZ 2107 for repair work will significantly save your time, improve the quality of maintenance and will guarantee the safety of your health.

The place where the machine will be serviced must have good and uniform lighting. In some cases, this can only be achieved through the use of additional lighting.
Due to the fact that the starter in the VAZ 2107 is located in the lower part of the engine, work on its dismantling should be carried out on an overpass or inspection hole. It is not possible to remove the starter from the top.

The machine must be securely secured using the parking brake or wheel chocks. Otherwise, there is a possibility that the vehicle will start moving spontaneously.

Video “Visual aid for repairing the starter unit”

The Budni Autobusiness channel presented a video showing in detail a guide to repairing starter mechanisms on classic VAZ models.

During operation of the machine, the mechanism wears out, which ensures that the engine starts. Replacing a failed starter or repairing it on a VAZ 2107 car is a rather complex operation that requires certain skills. The unit is installed on the right side of the engine in the direction of travel. The starter is equipped with a solenoid relay that activates the overrunning clutch.

The most common causes of engine starter failure:

Bendix failure;
high production of plain bearings - bronze bushings;
short circuit in the rotor or stator windings;
wear of brushes and current-carrying commutator.

A qualified replacement of faulty parts in the starter will restore its functionality.

Instructions for dismantling the starter on a VAZ 2107

Disconnecting the battery

The first step is to de-energize the machine's electrical network by disconnecting the battery.
Next, you should remove the mudguard, which will be present if the “seven” has an injection-type engine installed.
The fastening bolt, located at the bottom of the starter shield, is unscrewed using a socket wrench (the throat size of which is 10 mm) with an extension.

Unscrew the nuts

At the next stage, the three mounting bolts securing the starter with the clutch housing are unscrewed. To do this, use a 13mm socket wrench.
If the car is equipped with a carburetor-type engine, then the air duct and air filter must be dismantled. If the engine is of an injection type, then the intake manifold extensions must be removed.

Removing the starter

Using a 13mm socket wrench, the fastening nut located on the starter shield is unscrewed, after which the shield itself is pulled out.
At the final stage, you should unscrew the fastening nut connecting the electrical wires of the starter and the battery, after which you can remove the starter.

Installation of the starter is carried out strictly in the reverse order.

We install a new starter in its place.
We carry out installation work in reverse order.

Replacing the starter on a VAZ 2101-VAZ 2107

Welcome! Starter - after all, but without it it would be difficult, because if this unit does not exist, then who will start the car? Of course, you can get out of the car, push it a little and turn on the speed and it will start, but why are such difficulties necessary? That's why a starter was invented, thanks to which the car can be started only by turning the ignition lock cylinder. But over time, this unit breaks down and therefore it has to be replaced with a new one, but not everyone knows how to replace it, and therefore we have especially prepared for you instructions in pictures on how to replace the starter on cars of the “Classic” family.

Note! To replace, you will need to stock up on: A basic set of “10” and “13” wrenches, and you will also need to take with you a screwdriver, a “10” socket and an extension for this head!

Summary:

When should you replace the starter? It needs to be changed if:

It began to turn very poorly and therefore he began to start the engine of the car for a long time. (In this case, the starter can also be repaired; for information on how to repair it, see the article entitled: “Repairing a starter on a VAZ”)
It also needs to be changed if it has stopped starting the car’s engine altogether and thus it is no longer subject to repair.

VAZ 2107 starter repair - removing, replacing and installing the starter yourself

Hello, dear car enthusiasts! Especially hello, all owners of the VAZ “Seven”! Because this is exactly what we will be talking about – the VAZ 2107.

Although, the domestic auto industry has nothing special to boast about, given the model line and quality of cars produced, but still, there are examples of cars that should be paid attention to.

VAZ 2107 is a car that can deservedly be called a people's car. Thanks to its somewhat unusual design, this car stands out noticeably from the series of “classic” VAZ cars.

This fact, supplemented by minor design differences, was the reason why the model lasted quite a long time on the assembly line. At times it seemed that the “seven” would be produced forever, but time takes its toll.

Nevertheless, hundreds of thousands of cars of the seventh model are moving on the country’s roads, which will lead the popularity ratings among the “classics” for a very long time.

The design of the VAZ 2107 car is not fundamentally different from previous models. The biggest innovation in recent years has been the installation of an injection power system instead of the usual carburetor.

The rest is classic. This also applies to the starting system. That is why for every car enthusiast who bought a VAZ 2107, how to remove the starter remains a pressing question.

Removing the VAZ 2107 starter in the garage, do it yourself

As in most other cars, in the “seven” the starter is located at the bottom of the engine. In order to get to it, you need to have an inspection hole or overpass, since it cannot be removed through the top.

The inconvenient location is the only difficulty when dismantling the starter. Otherwise, everything is extremely simple; no special tools or special knowledge are required.

Removing the VAZ 2107 starter occurs only with the ignition off as follows:

First, remove the battery cover and disconnect the ground terminal;
the mudguard is removed, if one was installed in the lower part of the engine compartment;
For convenience, the battery and support can be removed;
the clamp of the wiring harness leading to the starter is unscrewed;
unscrew and remove the wires from the starter traction relay;
the three starter mounting bolts are unscrewed (two at the top and one at the bottom), after which the starter is removed under the car.

At this stage, the starter is completely ready for repair or maintenance.
