Disassembling the Lada Granta generator

Replacing the generator on Lada Granta 16 valves

At the preparatory stage, we will need the same tools and materials as in the case of the 8-valve Granta.

The design of the 16-valve modification of the Lada Granta has an alternator belt tensioner installed. This must be taken into account during repairs.

1. The car is in the perimeter of the repair area, the battery terminal has been removed, the oil pan is protected.
2. By analogy, we disconnect the power terminals from the converter and the protective cap.
3. The key is set to “13”, release the upper lock of the generator, move it to the right until it stops.
4. Remove the belt from the pulley.
5. Unscrew the lower fastening and remove the bushing.
6. We remove the generator from its regular place.

Generator drive

The Granta generator, like any other vehicle, must be driven in order to generate electricity. To rotate the generator, almost all cars use a belt, directly or through a bypass (tension) roller.

1 - Crankshaft pulley; 2 - Tension roller; 3 - Engine support; 4 - Generator pulley; 5 - Air conditioner clutch;

Generator belt

In Grant, a serpentine belt of various lengths is used to drive the alternator belt, and it depends on the additional equipment installed in the car, be it air conditioning, power steering, or the absence of them altogether.

The size of the Granta alternator belt starts from 823mm and can reach 1018mm depending on the vehicle configuration. You can read more about the alternator belt on the Grant here.

Tensioner

In some Grant engine designs, a special tension roller is used to tension the generator belt, which often tends to fail if the belt tension is incorrectly adjusted.

Incorrect tension can damage not only the tension roller, but also the bearings in the generator.

Replacing a generator on a Lada Granta with air conditioning

At the preparatory stage we will need the above tools and materials.

1. After unscrewing the converter mounts, hang up the front of the car, unscrew the bolts, and remove the right wheel.
2. Through the opening in the wheel arch we unscrew the tension roller and the engine mount mount.
3. We lower the car with a jack until access to the generator opens.
4. The further dismantling algorithm is no different from that described above.

We carry out preventive maintenance, replace the unit with a new one, and assemble the structure in the reverse order.

Where is the generator located on the Lada Grant?

On cars of the Lada Granta family, the current converter is located in the engine compartment, on the left side.

Engine compartment When carrying out repairs, you may experience difficulties with access to the converter mounts. For convenience, remove the oil pan protection and hang the front of the car.

How to change the generator on a 16-valve Grant

The generator mount on the 16-valve Granta variation is distinguished by the presence of a belt tensioning mechanism. Therefore, the procedure for replacing the generator on this model is slightly different. To work, you will need socket wrenches 8, 10 and 13. As when dismantling the generator from the 8-valve Granta, before starting work you need to remove the ground terminal from the battery to eliminate the possibility of a short circuit. After this, it is necessary to remove the engine protection by unscrewing the 4 front and two rear bolts securing it to the body parts. The 16-valve “Granta” generator is removed as follows:

• disconnect the block from terminal “D” on the generator;
• remove the rubber cap covering the “B+” terminal of the generator;
• Using a 10mm wrench, unscrew the nut holding the wire tip;
• loosen the tension bar nut using a 13mm wrench;
• by rotating the tensioner adjusting bolt counterclockwise, loosen the tension on the Grant generator belt (a 10mm socket wrench is required);
• move the generator towards the engine and remove the belt from the pulleys;
• Unscrew and remove the adjusting bolt of the belt tension mechanism from the generator mounting bracket;
• remove the tension bar;
• unscrew the lower nut securing the “Grant” generator;
• remove the spacer bushing and remove the lower mounting bolt;
• remove the tension bar;
• pull out the LADA Granta generator.

Signs of generator malfunction, ways to eliminate them

Generator replacement

Almost every owner of a Lada Granta knows that the standard generator often fails. And you can verify this by starting to operate this car. The reason for the failure lies in the unfinished design, which the manufacturers know about and which they do not want to correct.

Usually, it is not the generator itself that fails, but its support bearings or brushes, resulting in extraneous noise and an unpleasant grinding sound of parts rubbing against each other during a trip. It is also worth noting that in almost all Lada Granta models the generator is located in the engine compartment on the left side.

To eliminate the annoying sound and, in principle, get rid of the problem, you will need to dismantle the generator, diagnose the device and system, and, if necessary, replace worn elements or the entire generator. When viewing, it is important to pay attention to the electrical and mechanical components.

The procedure for replacing the generator depends directly on the vehicle configuration. However, in any case, the process involves carrying out preparatory and basic work. A detailed description of the replacement for each Lada Granta configuration is presented below.

2170-10

2170-13

Due to its smaller height, Bosch 110A is 10 mm lower than its analogue. Despite the minor advantages, BOSCH has one “fat” drawback - there is no possibility of quick (cold) replacement of the diode bridge in the event of its failure.

The electrical contacts are soldered into the bridge; quick replacement of the rectifier on the road will not work. At KZATE it is quite possible and acceptable to replace the rectifier on the road.

Difference between belts of 16 and 8 valve engines

For Lada Granta models, an alternator belt with the following markings is used:

• 1118-1041020-07: search index 6RK 823, length 823 mm, thickness 3.0 mm;
• 6PK1123 with air conditioning;
• 6PK1113 without air conditioning, with power steering;
• 6PK745 without air conditioning, without power steering.

General questions about working with the Grant generator

Let's consider general questions: everything except replacement.

Tension check

There are two approaches: visual assessment and physical.

Visual assessment of condition:

1. the car is on a flat surface, the gear is in neutral, the handbrake is off, the hood is open;
2. We don’t start the car - we put it in 5th gear;
3. We opened the hood and found a generator: we push the car back, resting against the bumper;
4. We inspect the required part along its entire length: are there any breaks or cracks? It needs to be changed.

Poor quality will lead to unexpected problems on the way.
Physical assessment :

• if you have a tool that measures pressure force: press the belt with a force of 10 kg*s - the deflection should be no more than 10 mm;
• there is no special tool: we try to turn it across - it should turn no more than 90 degrees.

How to tighten the alternator belt on a Grant

This section applies only to machines with a tensioner. No - change the part or see above how to install it.

Subsequence:

1. we use ring wrenches 8, 19;
2. Throw key 19 onto the lead screw;
3. wrench 8 for locknut;
4. we touch;
5. Now you can turn the lead screw: clockwise to loosen, counterclockwise to tighten;
6. got the desired result - tighten the locknut.

It is better to take ring wrenches, since a head with a ratchet or a wrench will not work.

When to change: technical regulations for replacing a VAZ 2190 belt

AvtoVAZ requires checking the condition of this part every 15,000 kilometers .

every 30,000 kilometers, regardless of condition.

How to remove a generator on a Grant

It needs to be removed for repairs, replacement of bearings or rollers.

The step-by-step process involves:

1. remove the negative terminal from the battery;
2. working with the generator: disconnect the wiring harness from it;
3. remove the cover of the power wire nut, remove the nut and remove the wire from the bolt;
4. unscrew and pull out the upper and lower fastening bolts - to work with the lower one, you may need to climb into a hole, throw off the tin protection of the internal combustion engine and dismantle it from below;
5. move the part to the right mudguard, remove the belt, and remove it.
