February 28, 2017 Lada.Online 28 592 0

The starter is removed in connection with its replacement, inspection or repair. On LADA cars, the starter is installed on the clutch housing at the front in the direction of travel. Before starting work, you should disconnect the negative terminal of the battery, drive the car onto an inspection ditch (overpass) and remove the engine protection.

On all modern LADA cars (Lada XRAY, Vesta, Largus, Granta, Kalina, Priora and Niva 4x4), removing the starter is performed in the same way. Installation is carried out in reverse order. Distinctive features of the process are presented below.

Lada Vesta is equipped with many electrical appliances, each of which is vulnerable to voltage surges. To protect consumers, there is a fuse in the circuit of each of them, and if for some reason it blows, it will have to be replaced, otherwise the electrical appliance will not work. Just first you need to find the Lada Vesta fuse box.

Why are fuses needed?

Fuses are elements of an electrical circuit that protect devices from voltage surges. They consist of a plastic case, two contacts and a working element.

The principle of their operation is simple: each element has an operating voltage, and if this value is exceeded, it will immediately burn out and the circuit will open. In fact, the protective component takes the blow, protecting electrical appliances from damage. Its purchase is much cheaper than replacing one or more consumers, which, among other things, can affect the control of the car.

Interesting!

The cigarette lighter in Lada Vesta has a fuse that blows more often than others. Usually the reason for this is connecting devices with high current consumption or several devices at once through a tee.

The required box is located above the battery, on the right side of the air filter. On the cover of the unit you can see warning signs in the form of a crossed out figure of a man with a hose and a lightning bolt.

To remove the cover, bend the two latches at the top and bottom. Be careful because... they are very fragile.

Self-replacement of the starter for Lada Vesta and X-Ray

The process of replacing the starter on Lada Vesta and X-Ray yourself is quite simple and does not require special knowledge or tools. In addition, the dismantling of this unit is carried out not only in connection with the installation of a new one, but also in the process of replacing the timing belt, etc. Therefore, it is worth understanding the situation.

The component itself is located in front of the clutch housing.

Dismantling

  • Before starting work, you need to drive the car onto an overpass or pit, and then remove the “-” terminal from the battery.
  • It is also necessary to dismantle the engine protection - on the Lada Vesta it is secured with 13 bolts, to unscrew which a 10mm wrench is used.
  • On the Lada X-Ray, the same 10mm wrench is used for operation, but there are not 13 bolts on the engine mudguard, but only 6.
  • Further, the algorithm for self-replacement of the Lada Vesta and X-Ray starter directly depends on the modification of the car.
  • Versions with manual transmission.

First you need to unscrew the 2 mounting bolts marked in Figure No. 1, and then remove the clutch hydraulic cylinder, which is No. 2. In this case, there is no need to disconnect the clutch hydraulic tube (under No. 3).

In the end, all that remains is to hook the cylinder to the technical hook.

  1. Regardless of the configuration.
  2. First, the nut marked No. 1 is unscrewed, after which the block with wiring indicated No. 3 and the terminal (under No. 2) are disconnected from the starter traction relay (under No. 4).
  3. Next, unscrew the 3 bolts indicated as No. 1, dismantle the hydraulic clutch cylinder retainer bracket, which is marked No. 2 (only for versions with a manual transmission), and also, using a Torx E10 bit, remove the starter.
  4. Installation of a new component and assembly are carried out in reverse order.
  5. This completes the independent replacement of the starter for Lada Vesta and X-Ray.

Lada Vesta starter: device, replacement, how it is installed and principle of operation

The starter is the main unit of the engine starting system. The unit spins the engine crankshaft to the frequency required to start the engine. The starter is powered by a battery. We will tell you in more detail about the design of the Lada Vesta starter at the end of the article.

What kind of starter for Lada Vesta

The Lada Vesta has an electric starter from Valeo. Its cost in stores is between 4,000 and 6,000 rubles. At official service stations, replacement will cost approximately 1,000 - 2,000 rubles.

Starter malfunctions Lada Vesta

To start the Lada Vesta engine, it is necessary for the air-fuel mixture to appear in the cylinders, as well as to ignite it using an electric spark. To do this, the engine must already be spun up to a certain speed using an electric starter. Problems with starting the engine most often arise due to a malfunction of one or another element of the vehicle's systems.

Installing a starter on Lada Vesta

For cars of all trim levels

We mount the starter (item 3, Fig. 3) and the hydraulic drive cylinder mounting bracket (item 2) (for cars with a manual transmission), secure it with three bolts (item 1). The tightening torque of the bolts should be 18…24 Nm (1.8…2.4 kgf.m). To perform these operations you will need: a ratchet wrench, an extension, a replacement Torx E10 socket and a torque wrench.

For vehicles with manual transmission

We install the clutch hydraulic cylinder (item 2, Fig. 1), secure it with two bolts (item 1). The tightening torque of the bolts should be 13...20 Nm (1.3...2.0 kgf.m), to perform the operation you will need a tool: a replaceable head for “13”, a torque wrench and a ratchet wrench.

To the starter traction relay (item 4, Fig. 2) we connect the terminal (item 2) and the wiring harness block (item 3). Tighten the nut (item 1) with a tightening torque of 18…24 Nm (1.8…2.4 kgf.m)

After this, install the engine protection and connect the ground wire terminal to the battery.

Electric starter device Lada Vesta

The principle of operation of a car starter is the same on all cars. Different starters have slight design differences, but once you understand the design of the starter, it will not be difficult for you to understand the features of another starter.

Each car starter has from 40 to 60 parts, but in the end there are only three main components:

  • Electric DC motor;
  • Traction (pull-in) relay;
  • Bendix.

The main unit is the electric motor, which rotates the crankshaft of the car engine through gears. Bendix and solenoid relays are auxiliary devices.

The retractor relay on the Lada Vesta, as on other cars, performs two functions at once:

  • Moving the bendix lever with the working gear;
  • Closing the contacts of the electric motor after the gear and flywheel ring are engaged.

Bendix got its name from the American inventor Vincent Bendix, who created this unit. The purpose of the bendix is ​​to provide a temporary connection between the starter shaft and the flywheel crown to rotate the engine crankshaft.

The principle of operation of the Lada Vesta starter

A starter is an electric motor that is powered by a vehicle's battery and serves to start the internal combustion engine. When you turn the ignition key in a car, the following processes occur:

  • The ignition switch contacts close and send current through the starter relay to the pull-in coil of the traction relay;
  • The solenoid relay moves inside the housing and pushes the bendix out of the housing, causing the gear to engage with the flywheel;
  • When the armature of the retractor relay reaches the end point, the contacts close and the current flows to the holding winding of the relay and the winding of the starter motor;
  • The engine spins up and starts. As soon as the flywheel rotation speed exceeds the starter shaft rotation speed, Bendix disconnects the starter gear and the flywheel using a return spring;
  • When the ignition key is returned to the first position, the supply of electric current to the starter is stopped.

Despite its apparent complexity, the electric starter in the Lada Vesta is a fairly simple mechanism.

Mechanical problems

The immobility of the crankshaft with an active starting device is the first sign of failure of the clutch, pressure spring, flywheel teeth, and retaining ring.

Also, problems in the power supply system will be indicated by a metallic grinding noise that accompanies the operation of the control unit. An equally frequent breakdown is the continuation of rotation of the launcher after starting the engine. The pressure spring, drive shaft, and contact plate are subject to mandatory inspection. And also, a retractor relay, a support bearing.

The cause of unstable operation may be third-party mechanical damage, the negative consequences of an accident, impact, or collision. Take these factors into account as well.

Generator repair

The price of a new Lada Vesta generator is very high. Therefore, in case of some breakdowns, it is more advisable to repair the unit rather than replace it. Restoring functionality usually begins by removing the power source from the vehicle.


Dismantled generator

For electrical problems, it is recommended to use a multimeter. Using a continuity test, you should make sure that there is no winding breakage, breakdown to the housing, or interturn short circuit.


Testing with a multimeter

Most often problems arise due to abrasion of the brushes. Replacing them allows you to restore reliable electrical contact.

Brushes

Abrasion of slip rings usually occurs during long-term operation of the generator.

How to check the ignition coil of a VAZ

If the ignition coil is faulty, the engine will not start. A characteristic sign of a faulty coil is its increased temperature when the ignition is turned off. This is easy to determine by touch.

Signs of a faulty ignition module may include the following:

  • hesitant engine starting or failure to start;
  • failures during sudden changes in speed;
  • high fuel consumption;
  • two cylinders do not work, the engine is feverish;
  • lack of dynamics;
  • a sharp drop in power;
  • drop in power and thrust after warming up.

These symptoms may not only be caused by the ignition module. To determine the malfunction, it is enough to spend a few minutes diagnosing spark plugs, high-voltage wires and caps. This will eliminate the remaining elements of the ignition system and make sure that it is the ignition module that is faulty.

Checking the ignition coil is performed in one of 2 ways. The simplest one is to remove the central wire from the breaker-distributor, bring it to the motor housing and turn it with the starter, and a running spark should appear. After this, we check the energy supply to a separate spark plug, for which we unscrew the working spark plug, bring its contact to ground and attempt to start the engine. In this case, the spark should come from the wire to ground. If it is absent, the reason will be a malfunction of a system element such as the ignition coil.

To check the module in the second way, we only need a multimeter, then follow the step-by-step instructions:

  1. We check the power supply and the presence of pulses supplied from the ECU. We check the power between the central terminal (15) of the wire block connected to the module and the engine ground. When the ignition is on, the voltage should not be less than 12 V. Otherwise, either the battery is dead or the ECU does not work.
  2. We check the pulses from the ECU on the wiring block. We install one tester probe on connector 15, the second on the far right, then on the far left. The assistant cranks the engine with the starter, and at this time we record short-term voltage surges with a tester. If there are no impulses from the ECU, it is he who is to blame.
  3. We check the resistance on the secondary windings of the coils. We put the tester in resistance measurement mode and measure it at the high-voltage terminals of the module cover. Between pins 1 and 4 and pins 2-3, the resistance should be 5.4 kOhm. Otherwise, the module must be replaced.
  4. We check the resistance of the primary windings between contacts 15 and the rightmost, then the leftmost terminals. Nominal - 0.5 Ohm. Deviation is not allowed.
  5. Check the module for a short circuit. In ohmmeter mode, install one multimeter probe on the central terminal, the second on the metal body. There shouldn't be any resistance. If the device detects at least some resistance (other than unity or infinity), the module must be replaced.
