Lada Priora starter: where is it located, how to remove it, replacement. Replacing a starter on a Prior

Many owners, at the first malfunction of the starter, change the entire unit, without understanding the causes of the breakdown itself. But in most cases, the reasons for failure are as follows:

Failure of the solenoid relay - purchased and replaced separately
Brush wear
Burning dimes on the retractor relay

Each of the problems listed above can be solved much cheaper than buying a new starter for a Priora. Therefore, first you should contact a specialist who will tell you exactly what the reason is and answer whether it can be repaired or not!

If repair is no longer possible, which is extremely rare, then a replacement must be made. To do this you will need the following tool:

13 mm head
extension
ratchet or wrench

What does it consist of?

The starter is an electrical machine with a fairly large power consumption. When starting, it receives power from the battery and is the main consumer that can quickly discharge it.

The starter has a common design with a brush-type DC motor.

Its main parts are: stator, rotor, brush holder and brushes, bendix, solenoid relay.

All of them are involved in the operation of the starter and the failure of one element will lead to its complete stop.

Required Tools

In order to remove or install the starter on a Priora, you will need the tools from the table below.

Table - Tools required to replace the front strut

Name	Note
Spanner	"at 13", "at 15"
open-end wrench	"at 13", "at 15"

Replacing the starter on a Lada Priora can be carried out without access from the bottom. If you don’t want to remove the air filter and the wires going to the sensors, then you can dismantle and install the unit from underneath. In this case, you will need an inspection hole, overpass or lift to access the place where the starter is located.

The procedure for replacing the starter on a Priora with your own hands

This repair is very simple, so it won’t take more than 25-20 minutes. The ideal option is to work either in the inspection hole, or to remove the air filter housing from the cushions, after which very good access to the starter opens.

First of all, we disconnect the “-” terminal from the car’s battery, after which we disconnect all the wires from the starter, one of which is screwed on with a nut.

Then you need to unscrew the three starter mounting nuts, one on top:

And it’s more convenient to unscrew two from the bottom, as clearly shown in the photo below.

When they are unscrewed, you can easily remove it, since there are no more fasteners left.

Installation of a new one during a complete replacement occurs in the reverse order, and no difficulties will arise when performing this repair.

It is important to keep in mind that the starters on the Priora were installed with both three fasteners and two (old and new). Therefore, before buying a new one, make sure which one was on your car.

The price of a new 2170 can range from 3,500 to 4,000 rubles, although you can find Chinese options a little cheaper, but of relatively dubious quality. The most reliable and problem-free are KZATE factory production, which can easily cover over 200,000 km of a vehicle without repairs.

Article number and approximate price for the original Lada Priora starter

There are two types of starters installed on Lada Priora cars. They differ in power and mounting method. The units are not interchangeable, so it is important for the owner to know which starter is installed on his car.

The original unit with a power of 1.4 kW has article number 21100370801002. The cost of a new product is from 3600 to 4000 rubles. At car dismantling yards, spare parts can be found with a price starting from 800 rubles. However, most used starters are in very poor condition.

The Priora uses a 1.8 kW starter. The branded unit comes with catalog number 5702370815. Its price ranges from 2300 to 4100 rubles for a new product. A used spare part will cost from 900 rubles.

Priora starter relay where is the photo located

If the starter does not work when the ignition key is turned to position “II,” there may be a malfunction of both the starter itself and its activation circuit. To check, turn off the ignition and disconnect the wire block from the terminal of the starter traction relay windings.

Using a screwdriver, we bridge the terminal of the traction relay and the tip of the wire connected to the “positive” terminal of the battery. If the crankshaft rotates, then the starter is working, and the cause of the malfunction is a violation in its activation circuit. Otherwise, the starter or its traction relay is faulty. If it is not possible to eliminate the malfunction in the activation circuit of a working starter, then, if necessary, in this way (by turning on the ignition and closing the terminals), you can start the engine and drive to the repair site. A malfunction in the starter switching circuit can be caused by damage to: the starter relay, the power circuit or relay control circuit, the ignition switch contact group. To troubleshoot the starter circuit...

...in the car interior we remove the starter relay and fuses from the mounting block. To check the starter relay, install a known-good relay type 902.3747-11 in its place. To do this, you can use the adjacent heated rear window relay. If the starter turns on with the newly installed relay, then the starter relay has failed and must be replaced. If not, check the power circuit and starter relay control circuit. To check the power circuit, remove the starter relay from the mounting block.

We insert a jumper (piece of wire) into the sockets of the power contacts of the relay “30” and “87”. We turn the key in the ignition switch to position “II” - “starter”. If the starter turns on, the power circuit is working, if not, then we check it with a tester...

...is “+12 V” supplied to socket “30” of the starter relay when the ignition key is in position “II”. In this case, the second (“negative”) tester probe can be connected to the head of the instrument panel mounting screw. If voltage is supplied to socket “30”, use a tester to check the integrity of the circuit from socket “87” of the starter relay to the tip of the starter traction relay control wire. If voltage is not supplied to socket “30,” we check the circuit from terminal “50” of the ignition switch to socket “30” of the relay. If the circuit is in good condition, it is necessary to replace the ignition switch contact group. If the starter power circuit is working properly, check the starter relay control circuit. To do this, insert the tester probe into socket “86” of the starter relay, connect the second probe to ground. With the ignition on, check...

...is “+12 V” supplied from the main relay of the engine management system to socket “86” of the starter relay. Then we insert the tester probes into the relay sockets “85” and “86” and check...

...is there ground in socket "85" of the relay... ...connected to terminal "50" of the controller. Otherwise, we check the integrity of the starter relay control circuits: from the main relay of the control system and output “50” of the controller - respectively to sockets “86” and “85” of the starter relay.

Description of the Priorov starter

Before we talk about how to repair a starter, let's get acquainted with the basic description of the mechanism. Let's start with the purpose and location.

Purpose and location

An electric starter is a unit used to convert electrical energy into mechanical energy, which is necessary to start the engine. In fact, this mechanism is an electric DC motor equipped with a mechanical drive. The principle of operation of the device is to close the retractor and retainer coils, as well as move the core, which helps push out the bendix. As a result, the Bendix engages with the flywheel of the power unit, and under the influence of the anchor, this flywheel begins to spin. Accordingly, this leads to the engine starting. In Lada Priora cars, the starter unit is located on the gearbox, under the housing of the engine air filter element.

Which starter is better to install on Priora?

Today you can find many models of starters on sale from various manufacturers, but they are all divided into geared and gearless. Both one and the second type have both their advantages and disadvantages. The main advantage of the gearless version is reliability and the ability to repair in case of breakdown, which is due to its fairly simple design. As for the disadvantages, such mechanisms are characterized by high voltage consumption and heavy weight.

Geared devices began to be used relatively recently; the addition of a gearbox to the design made it possible to improve the technical characteristics of the unit as a whole. The main advantage is considered to be higher reliability of engine starting, in particular at low temperatures. This advantage is achieved as a result of increased torque. The electric motor itself is smaller in size, but the rotation speed of the device is higher, and accordingly, less current is required to start the motor. In the production of geared devices, fewer expensive materials are used; accordingly, their cost is an order of magnitude lower than that of gearless ones.

As for directly choosing a starter, in practice geared devices are more reliable and fail much less frequently than gearless ones. But in this case, you need to remember that under no circumstances should you allow the starter mechanism to operate while the power unit is running. This is because the rotation frequency of the armature will be several times higher; accordingly, its conductors can come out of the grooves and touch the stationary components of the device, thus destroying its structure (video author - CompsMaster).

Operating principle of the part

Essentially, the starter device helps start the car and all its systems. As for the principle of operation of the starter, everything happens according to the following algorithm:

After the driver turns the key in the ignition, current is transferred. The signal goes to the machine's motor winding.
Next, a part of the starter called the bendix transmits the impulse to the flywheel.
As soon as all the car systems are started, the Bendix returns to its original order. Here the starter completely finishes its work and stops.

Thus, it is clear that the work of the starter consists only of the ignition process, in the form of assistance to the motor. There are a variety of starter options.

In addition to this difference, they can be varied depending on the friction composition. There are specialized models for more powerful diesel engines that have advantages over standard ones

So when repairing a VAZ or any other starter with your own hands, pay attention to its type.

Basic faults

The starter has several basic faults that occur quite often.

Battery;
Solenoid relay;
Brushes;
Bendix;
Rotor and stator windings;

If the starter does not rotate or clicks appear when you turn the ignition key, then the battery is most likely discharged. If the battery is charged, you should check the condition of the marks on it. Poor contact or oxide on the stamps will interfere with starting the car, since the starter requires a large current to rotate the engine, and weakening the contact of the stamps or their oxidation will increase the resistance, which will make it impossible to start the internal combustion engine.

battery

Retractor

If, when you turn the key, the starter rotates but does not start the engine, then the culprit is most likely the solenoid relay. The main culprit for relay failure is a break in its winding.

Brushes

Brushes are the most common starter element that fails. If they wear out, starting the engine is impossible, since they do not provide contact with the rotor commutator. When the brushes are worn down to 4 mm, they must be replaced.

Bendix

The Bendix is a type of overrunning clutch that engages the gears with the flywheel. Its failure is a mechanical failure of the starter. It is impossible to repair it, just replace it with a new one.

Windings

The winding fails due to increased currents generated when the engine starts in cold weather or when the bendix jams. The wire wound on laminated steel simply cannot withstand such current surges and breaks. This can be solved by replacing the rotor or stator, and best of all the starter.

Principle of operation

When you turn the ignition key, voltage appears on the coil of the solenoid relay, which attracts the core.
The core pulls the bendix out of the starter housing and engages it with the flywheel.
As soon as the bendix engages the flywheel, a short circuit occurs, voltage is applied to the brush holder and causes the starter rotor to rotate.
The rotor begins to rotate the bendix through the gearbox, thereby rotating the engine crankshaft and starting it.
As soon as the engine starts, you release the ignition key, the voltage disappears on all elements of the starter and the retractor, under the influence of the return spring, disengages the bendix from the flywheel.

Replacement

Work on removing and installing the starter can be carried out without a higher education as a mechanic. Using the step-by-step instructions below, anyone who has ever held a key in their hands can cope with the task.

Necessary tool

Phillips and flat head screwdriver
Ratchet, extension and socket for “13mm” and “15mm”
Open-end wrench for “10mm” and “13mm”
Penetrating lubricant (WD-40)
And the desire to repair your own car with your own hands.

Step-by-step replacement instructions

Work can be carried out both from the inspection hole and from above. We will consider the option of doing the work from above, as it is simpler and more convenient. And not everyone has an inspection hole.

First of all, disconnect the negative terminal of the battery and remove the air filter housing along with the mass air flow sensor.

Then, on the solenoid relay, use a 13mm open-end wrench to unscrew the power wire and remove the “mother” chip from the relay (marked with red arrows in the picture).

Using a ratchet with a 13mm socket and an extension, unscrew the two starter mounting nuts. Below and above.

Next, we remove the starter from the engine compartment and inspect it.

We install it in the reverse order and check its functionality by test running the car.

Replacement from under the bottom of the car is similar to the instructions outlined above, but only to carry out work from an inspection hole or overpass it is necessary to remove the engine crankcase protection.

Replacing the Priora starter, main faults

The car starter starts the engine. The Priora will not start without his participation. Without it, starting a movement is simply impossible. Sometimes the Lada Priora does not start because the fuse has blown, or the starter relay has malfunctioned; it is marked K3. Sometimes it clicks but doesn't turn. The reasons are in the details.

The starter on a Priora consists of the following parts: bendex, retractor relay, armature and others - for a complete list of how many parts the starter of a Priora car contains, see the article below. It is advisable for car owners to know where this mechanism is located on a Lada Priora car - it is located immediately under the air filter.

The price of the part is a starter for a Priora engine (16 valves): from 2750 to 4500 rubles. When a breakdown occurs, the device on the Priora stops turning.

Standard starter and analogues - article number and price

Unfortunately, if the mechanism does not work, the problem can only be solved by replacing it. Neither installing new parts under the body, nor any cleaning will save the situation. The standard starter for a Priora with 16 valves goes under catalog number 2111.3708010-01, its cost is about 4,000 rubles. As analogues we can consider:

Lada Priora starter: device and principle of operation

As mentioned earlier, this part can be installed on the Priora of two types: geared and gearless. Sometimes it may be necessary to remove the starter, note that it is located under the engine, on the right - closer to the space under the air filter.

To ensure that the starter unit does not wear out so quickly, it has a special mechanism that disengages the gear from the crankshaft flywheel - the Priora starter retractor relay. If it were not there, the service life of the unit would be greatly reduced, or repairs would be required.

Geared

This mechanism is small in size. It turns out this way because the gearbox allows you to increase or decrease the torque. The planetary gearbox itself in the car in question is located between the armature and the bendix; it serves as a “buffer” and an intermediate part between them. Thus, it does not take up so much space in the case, under which there are:

bendix;
fork;
anchor;
stator;
solenoid relay;
mask;
gearbox

Its main difference is that the bendix is fixed on its own shaft, and it interacts with the Priora engine through a gearbox.

Gearless

A gearless starter is much larger than its counterpart, but it does the same job of receiving electrical energy from the battery and sending it to the crankshaft to start the engine. It consists of the following components:

relay;
an electric motor containing the traction relay cores and winding;
brushes and holders, “brush assembly”;
solenoid relay;
stator;
fork;
contact bolts;
anchor;
starter mask;
retaining ring;
freewheel;
front bushing and rear bushing;
starter bendix Priora;
gear.

The gearbox operates according to the following algorithm:

Power is supplied from the battery through the wiring harness.
The anchor is retracted.
The Bendix is attached to the gear, “thrown out”, the pin contacts are closed, and voltage is applied to them.
The armature rotates, the torque is transmitted to the bendix, through it to the gear, and it is already in contact with the engine flywheel.
As soon as the ignition key is released, the retractor relay disconnects the bendix and the gear.

Basic faults

Externally, a breakdown of the Priora starter can be recognized by the following signs:

“turns” and at the same time starts the engine;
does not “twist”;
continues to “twist” after the key is released;
creaks, clicks are heard;
It spins, but for too long.

The reason may lie in a faulty battery, in the starter itself and fuses. The most common are those that are most likely to disable
the car – it’s worth taking a closer look.

Doesn't turn on

If the engine does not start, the problem may be:

discharged or broken battery;
no closure of contacts 50 and 30;
terminals or tips are oxidized;
interturn closure;
short circuit to ground;
open circuit “starter - traction relay”;
the ignition module is faulty;
break in the traction relay winding;
brush wear;
the anchor jams;
the additional relay or the control circuit connected to it is damaged.

Starter problems and their elimination

If the starter clicks but does not turn, then first of all attention should be paid to the battery. Most likely, its charge is not enough to start the car. You should also inspect the condition of the terminals. More rarely, the culprit for clicking is the traction relay.

If the starter does not turn the crankshaft of the power plant, then conditionally possible causes can be divided into mechanical and electrical. The first most often includes problems with the clutch or drive gear. If there are any malfunctions, the listed elements must be replaced.

In the electrical part, the weak point is the brushes. They are the most susceptible to wear and tear. When the remaining length of the brushes begins to be 4 mm or less, they must be replaced.

How to replace the starter on a VAZ 2170-VAZ 2172?

Removal: The starter belongs to the electrical part of the car, therefore, during any work with it, you need to de-energize the battery by removing the minus terminal from it (How to remove the terminal, read the article: “Replacing the battery on a car”, point one), after this has been done operation, remove the air filter housing, as it prevents access to the starter (How to remove the housing is described in the article entitled: “Replacing the air filter housing on a VAZ”) and proceed to unscrew the nut (Indicated by the red arrow), securing the wire terminals and disconnect the terminals, then disconnect the wire block (Indicated by a blue arrow) from the terminal that is present on the starter and unscrew the two nuts securing the starter to the clutch housing, one of these nuts is indicated by a yellow arrow in the photo below for clarity:

Installation: Installation of a new electrical element is carried out in the reverse order of removal, the wires are connected exactly to the same places where they were.

Additional video clip: An interesting video is located just below, it tells what advantages a new starter installed from another company gave, and you can clearly determine this even from the video clip.

How to change the solenoid relay?

One of the main parts of any starter is the solenoid relay, which is located next to it. This mechanism performs two functions at once:

supplies voltage to the stator and rotor windings;
moves the bendix, which engages the starter gear with the flywheel crown.

Frame.
Two threaded power contacts.
There is a coil inside.
The core is made of metal, which is affected by the electromagnetic field of the coil. It also has a kind of “hook” for connecting to the bendix.
Contact Group.

To replace the solenoid relay you need keys 10 and 13, as well as a screwdriver. First you need to disconnect the battery.

To do this, use a 10mm wrench to loosen the terminal. Then you can proceed to disconnect the solenoid relay. To do this, use a 13 mm wrench to unscrew the two nuts on the power contacts. The relay is attached to the starter housing using 2-3 bolts (depending on the specific design). They need to be unscrewed using a screwdriver. This completes the dismantling; installation of the new relay is carried out in the reverse order.

Dismantling works

After opening access to the starter, you must perform the following steps:

First, you should disconnect the control connector, for which the locking tab is lightly pressed;
Then the rubber cap is moved aside and the nut is unscrewed using a 13mm wrench from the terminal;

The power terminal is removed, after which the three mounting screws located at the top and bottom are unscrewed with a 13 key.

Note that you need to start with the two lower screws, and the top one should be unscrewed last, while the starter housing must be held, then the housing is carefully tilted back. Installation work is carried out in the reverse order of dismantling.

How to remove the starter for replacement or repair?

Now let's talk about the case when it is necessary to completely remove the starter on a Priora. There may be several reasons for this - from repairing the clutch to replacing the starter itself. But if the reason lies in the fact that the car cannot be started, it is worth checking whether the starter is really to blame. Quite often the reason lies in other nodes. And if the Priora does not start, the starter is not always to blame.

In order to dismantle the mechanism, you will need to perform simple manipulations:

Turn off the power - use a 10mm wrench to loosen the terminal.
Using a 13mm wrench, unscrew the nuts that secure the starter housing to the engine block.
Using the same wrench, unscrew the nuts on the solenoid relay.
Remove the wire from the relay.
Remove the starter through the bottom or top (provided that the air purification filter housing is removed).

Typically, repairing a starter on a Priora consists of changing the brushes, cleaning the lamellas, installing a new bendix and retractor relay. If there is severe damage to the housing or windings, then it will be more effective not to repair, but to completely replace the unit.
