How to remove and replace the starter on a VAZ-2112 16 valves – Taxi Bolt

The starter relay performs an important function on any vehicle, regardless of model.

Device characteristics

The engine starts by turning the crankshaft driven by the starter. The device is a motor that supplies direct current. Its power is determined by the speed of rotation of the crankshaft and the moment of its resistance when turning.

The VAZ 2110 starter assembly itself consists of several elements on which correct operation depends:

1. Winding that draws in and holds parts.
2. Anchor.
3. Traction relay.
4. Starter brushes.

All components work in several stages. The starter unit drive starts the armature shaft gear. Then the shaft begins to rotate, and with it the gear, which turns the knee.

How to choose a good starter?

If there are many offers from different suppliers, the price of a car starter for one type of car will differ significantly from the cost of starters for another car. And products from different manufacturers will have different prices. It's not only about the popularity of the brand, but also about the quality of production. For example, Belarusian ATEK starters have a number of advantages:

• equipped with a gearbox, they are more powerful and reliable than conventional devices;
• less susceptible to temperature influences;
• high-quality bearings and waterproofing increase their service life;
• Rugged protective housing, copper contacts, factory assembly and certified components.

The decision to replace the starter usually comes after the old one breaks down. Before this, you can notice a number of indirect signs, by which it becomes clear that the starter does not have long to work. For example, grinding and strange sounds during its operation, the retractor relay not operating, or the starter not turning off when the engine is running.

Catalog number and cost of a good starter for Lada Priora

Car owners have a predominantly negative attitude towards original starters on Priora. This is due both to a large number of defects and to the presence of breakdowns that are not typical for starters from other manufacturers. For example, it is not uncommon for stator magnets to come off. Therefore, drivers recommend paying attention to analogues. Among them there are many decent options at an affordable price. The tables below provide a list of brands that have proven themselves in use in a car.

Gear starter with internal gearing (planetary).

The planetary gearbox consists of a ring gear, a sun gear and three satellite gears. The ring gear is a circle with teeth on the inside. Its outer part is connected to the body through rubber gaskets that provide shock absorption. The sun gear is connected to the armature shaft of the electric motor and is located inside the main gear and connected to it through the satellite gears. The satellite gears are mounted on carrier pins, on a shaft with a bendix shaft. When the armature rotates, torque is transmitted through the satellites to the ring gear, but since it is rigidly connected to the body, the satellites rotate around the sun gear and rotate the carrier with the bendix. The rotation speed of the bendix depends on the gear ratio of the sun and main gears.

The electric motor of a gear starter is designed in the same way as a simple one, but has design features. It is more resourceful and less material-intensive. The only difference is in the armature shaft, which does not have a part with splines along which the bendix moves. The difference between a gear starter and one that is simple in transmitting torque from the armature shaft to the flywheel crown.

Advantages of the gear mechanism

The gear starter on the VAZ-2107 has the following advantages over the old product:

• ensures faster engine starting;
• significant increase in product service life;
• increasing the power of the mechanism with reduced energy consumption;
• reduced size and weight.

The main advantage of the updated device model is its increased energy efficiency parameters. Thanks to these parameters, starting the engine is possible even with a dead battery. Starting the engine can be done not only in hot weather conditions, but even in severe frosts, when starting a car with a conventional starter is almost impossible.

The gear-type mechanism allows you to save battery charge, so this type of product is much better than older designs. The service life of such a product depends on the number of engine starts, but in any case it will last longer than the old modification of the device.

Design and operating features

To find out why the product is effective and reliable, you should consider the design of the gear starter. The main difference between a gear starter is the presence of a gear located between the armature and the bendix. The effectiveness of the device is due to the fact that the product is equipped with a reduction gearbox, through which the torque can be increased. The most proven starters are those based on a planetary gearbox design.

Features of the functioning of the gear unit on the VAZ-2107 are no different from the usual:

• A voltage of +12V is supplied to the terminals of the solenoid relay.
• An electric current begins to flow in the winding and armature of the device.
• The retractor relay moves the gear along the armature shaft and engages it with the motor flywheel, at the same time the starter itself begins to rotate.
• The flywheel rotates and the engine starts.
• As soon as the power at the terminals disappears, the relay returns the gear mechanism to its original position, and the starter is turned off at this time.

The gearbox used in the design of a modern device will increase its efficiency by 50%, making it more efficient and reliable. Thus, the load on the battery is significantly reduced.

Features of installation of a gear starter

If the old starter is constantly bothering you, then now is the time to replace it with a more modern model. To replace a VAZ 2107 you will need to use a standard set of tools. The replacement process is very simple and does not require special skills. The new unit is installed to replace the old one without any modifications.

1. Initially, be sure to disconnect the negative terminal from the battery.
2. Using a wrench set to “13”, it is necessary to unscrew the bolts securing the product, as well as the power cable bracket.
3. The plug is removed from the control wire.
4. Now you can dismantle the old product.
5. The new product fits perfectly into the place of the old one, despite the significant discrepancy in size.
6. We proceed to tighten the bolts securing the product.
7. Don’t forget to reinstall the power wire and then secure it with a nut.
8. Now you can connect the battery and start starting the engine.

You will be pleasantly surprised by the functionality of such a small but reliable assistant. The gear starter does not fail in winter; it can be used for frequent engine starts. The last thing that is important to mention is the cost of the mechanism. Despite its size, the gear mechanism for a VAZ 2107 costs about 2500-3500 rubles. But it’s better to pay and enjoy the new mechanism than to continue to live in agony with the old one. This mechanism is produced for the entire range of the Zhiguli family, which can significantly improve the starting parameters of the engine. After replacement, problems with difficulty starting the engine when the battery charge is low will no longer be so relevant, so you need to rush to get a new mechanism.

DIY connection instructions

Removing the starter in the engine compartment
So, if you decide to install a new mechanism, then first you will need to dismantle the old one.

How to properly remove and install a new device, what its connection diagram is, read below:

1. To begin, turn off the engine and turn off the ignition. Then open the engine compartment and disconnect the battery. All repair work related to the electrical part must be carried out with the vehicle's electrical network de-energized. If the battery is not disconnected during removal, this may result in voltage surges in the system, which can lead to failure of the starter mechanism or other electrical equipment.
2. When the battery is disconnected, you will need to dismantle the crankcase protection of the power unit. To do this, crawl under the bottom of the car and unscrew all the bolts that secure the protection, then remove it, and put the bolts nearby so as not to lose it.
3. Now you can begin dismantling the element. To do this, first find where the device is located. First of all, you need to unscrew the nut of the upper mechanism lock. Unscrew it with a wrench and set it aside.
4. The next step is best done under the bottom of the car. Reach under the vehicle and disconnect the cable that connects to the traction relay terminal. If the connection is bad, there are traces of rust or oxidation on it, then at the same stage, clean the contacts; for this you can use a construction iron brush.
5. After these steps are completed, you need to unscrew the nut and disconnect the cable that is connected to the contact screw of the traction relay.
6. Next, all you have to do is unscrew the nut, which is located on the lower mechanism lock. Now you can dismantle the starter device and replace it with a more functional and efficient one. Further installation is carried out in reverse order, do not forget to connect all the nuts and bolts. Before connecting wires, check the quality of the contacts to prevent possible problems in the future.

Basic faults

The starter has several basic faults that occur quite often.

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.

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.

Which starter should I install?

If the starter or its elements break down, the device must be completely replaced. In stores you can find a wide range of parts, but they are all divided into 2 types: with or without a gearbox.

A gear starter is a small-sized electric motor with low current. Its main difference: high starting torque, power and heavy weight. The starting ability of such a mechanism is much better than usual.

Gear mechanisms are much easier to maintain and have a long service life. They allow you to crank the crankshaft for a long time, even if the battery is already discharged. But it is worth remembering that such operation can lead to damage to the unit.

In starters without a gearbox, movement is transmitted to the gears from the unit itself. The design of the devices is very simple and easy to repair. Compared to gear units, this is the main advantage.

Experts recommend installing gear starters in the VAZ 2110. They are durable, reliable, and work great.

Original starter

The standard starting device for Lada Priora cars is a classic VAZ one - BATE 2111.3708010-01.
Suitable for all types of internal combustion engines, including those with an electronic control system, but manufactured before 2010. The starter consists of a traction relay, an overrunning clutch and other important parts. Location: under the air filter. The price of original spare parts starts from 4,000 rubles. Below are the technical specifications:

• power - 1.2 or 0.9 kW:
• battery capacity - 55 Ah;
• direction of rotation - left;
• weight - 4.7 kg;
• voltage - 12 volts;
• number of teeth - 9.

This car is equipped with not only gearless, but also geared types of starters. They are small in size and allow you to control torque. The planetary mechanism is located here between the armature and the bendix. The power of such devices varies between 1.4-1.8 kW. They are installed on Prioras released after 2010. The place - on the right in the direction of travel of the car - is connected to a new cable gearbox.

Several starters are suitable as analogues for Lada Priora:

• "Baker" 5702370800010;

The price of devices varies between 2.7-4.5 thousand rubles.

Required Tools

In order to carry out repairs yourself and replace the starter on a VAZ 2112, you need the tools from the table below.

Table - Tools required to replace the front strut

Gear starter repair

Since the engine starting unit has friction parts and is equipped with an electrical part, breakdowns still occur. The complex design of the gear starter in some cases makes repairs unprofitable; this unit is completely replaced. However, in some cases, the car owner can identify and fix the problem on the spot.

Solenoid relay failure

In this case, repairing a gear starter requires complete disassembly of this engine starting unit. Experts recommend taking a photograph of the solenoid relay before disassembling it, so as not to confuse the polarity of the contacts. If the relay is dismountable, visually inspect the “nickels”; if they burn, they can be cleaned with sandpaper; if there is significant wear, it is better to replace them entirely.

Start problems

If, when you turn on the ignition with the key, you hear the characteristic sound of the retractor relay operating, but the flywheel does not spin, most likely the bendix has worn out. In this case, the starter drive should be replaced entirely, preferably in a specialized service center.

In any case, it is necessary to check the battery charge level; perhaps the starting current is not enough, even for a gear starter that sharply increases torque.

No response to the ignition key

This malfunction of the gear starter is most often caused by an interruption in the circuit. To restore the functionality of the starting unit, you must:

• tighten the terminal fastening nuts;
• clean oxidized terminals if necessary to restore contact;
• checking battery charging, charging as necessary;
• revision of the bendex and its replacement if necessary; this part is not subject to restoration.

This breakdown, in principle, does not require a visit to a service station; it can be easily repaired on your own.

Magnets falling out/sticking

When disassembling a failed starter, it is very difficult to maintain the original order of the permanent magnets. In principle, inserts piled up in a heap are not a problem for the car owner if there is a compass. Using the random method, you can put them in the required sequence with a 30–50% probability, so you should approach the repair yourself systematically:

• for normal operation of the starter, 3 magnets are used with the magnetization vector directed outward, and the same number with the opposite direction of the magnetization vector, but inward;
• they must be alternated with each other when installing in a cage;
• the magnetization vector is determined by the compass, for this purpose the insert is installed on the edge near the device, for three magnets the arrow will turn towards them with the north side, for the remaining ones - with the south side;
• They stick to the cage body independently; their relative position in the starter is achieved through spacer polymer rings on both edges of the inserts.

In order for the armature to operate (rotate) in the desired direction, it is necessary to place the starter vertically, put the lower remote ring on it, and then the housing, placing the “+” wire retractor slot on the relay side.

Then the housing is removed together with the lower remote ring, the magnets are installed alternately north/south, and are fixed with the upper remote ring, taking into account the holes for the tie rods.

The brush assembly in the form of a repair kit is mounted after installing the cardboard insulation in the groove of the positive wire.

Attention: Before installing the starter in place, it is necessary to check its characteristics. To do this, you should rotate it when connecting it to the battery and make sure that the retractor is working.

Thus, some faults of the gear starter can be eliminated on your own. However, to ensure guarantees, it is better to visit a service station, where professionals do not make mistakes and advise the user on choosing a starter or repair kit from a specific manufacturer for their car.

The starter doesn't turn over

There are many reasons why the starter does not work, but first of all you need to check the most common reasons why the engine will not start.

Checking contacts on the battery

Often the reason when the starter does not turn is due to loose terminals on the battery or their oxidation. It is enough just to clean the oxidized terminals from chemical reactions and tighten them with a force that will ensure reliable contact.

Battery discharge

Quite often, especially in winter, after a period of inactivity, the car’s battery may discharge, and thickened oil during parking will not allow the weak battery to rotate the crankshaft with the starter. You can check the battery with a regular multimeter; in winter its voltage should not be less than 12V, in summer not less than 11V. This voltage is not an indicator of the battery charge; at such values ​​it is better to charge the battery.

Egnition lock

In some cases, the contact part of the ignition switch may fail. This is due to aging or poor quality parts. In this case, when turning the key, the contacts will not close to turn on the starter.

Winding break

If the winding on the stator or rotor of the starter breaks, the magnetic field that rotates the armature will not appear and the starter armature will not move.

Starter replacement

It is carried out using the following tools:

• set of screwdrivers;
• devices consisting of a ratchet, extension and sockets;
• set of wrenches;
• lubricants that soften fasteners - VD-40 and similar.

Work should be carried out in an inspection pit or use a lift. It is much more difficult to dismantle the starter from above. However, in some cases there is nothing else left to do. Below is a step-by-step algorithm of actions:

• de-energize the battery;
• remove the air filter housing and mass air flow sensor;
• unscrew the bolt and remove the chip from the solenoid relay;
• unscrew the starter mounting bolts using a ratchet tool;
• Remove the starter from the engine compartment.

Tractor

It is also worth mentioning the installation of gear starters on agricultural machinery. To start diesel engines, special starting engines were installed on tractors. For example, the popular MTZ-80 tractor was equipped with a PD-10 starting engine (“starter”). It was filled with gasoline mixed with oil and worked until the main engine started.

View gallery

Its main disadvantage was that it required the same maintenance as the diesel itself - repair, adjustment, refueling. Therefore, it makes sense to install a more technically advanced starter (gearbox) on the MTZ-80. Its characteristics indicate that this is a completely worthy replacement for the launcher: power from 3.5 to 9 kW and the required battery capacity of 190 Ah are fully consistent with the MTZ-80 engine. Depending on the tractor modification, the starters are adapted for a 12 or 24-volt electrical system. But in general, this solution is very profitable and just as easy to implement as for passenger cars, since adapter plates for installing the mechanism instead of the starting motor and all the necessary switching are available for sale.
