Lada Granta car generator repair

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.

How to replace the Grant alternator belt

The replacement process is not simple and depends on the equipment of the car: whether there is a tensioner, air conditioning. In the latter case, you cannot do without a lift and dismantling the engine mount due to the air conditioning compressor clutch pulley.

For a Granta with air conditioning, for installation you will need to hang the wheel and remove one engine mount.

How to change a belt on a Grant 8 and 16 valve without air conditioning and tensioner

What you will need for work :

• a knife, if you just need to cut off an old part;
• crank or ratchet with head 13;
• long strong wire;
• flat screwdriver;
• partner – you can replace it yourself, but it’s easier with an assistant.

Step 1. Dismantling

The car is on a flat surface, neutral is engaged without the handbrake. The battery is disconnected .

If the old belt is not needed, we cut it in an accessible place and take it out.

If you need to save the old one, do everything up to step 3.

A replacement is needed with a length of 8223mm, six-wedge. Called 6RK 823. PHOTO: www.zr.ru

Step 2. Remove the generator mount

We approach the generator mount with head 13:

1. we remove the lower bolt by 2-3 turns;
2. Use it to completely unscrew the top bolt.

In this situation, we proceed to installation. PHOTO: www.zr.ru

Step 3. Raise the part

Scroll the generator up. The top mount becomes higher than the bracket to which it is screwed.

We press the part to the engine. We fix it with strong wire. For example, we hang it from the cylinder head bolt.

In this situation, we proceed to installation. PHOTO: www.zr.ru

At this stage, you can remove the old part if you did not cut it. We engage fifth gear and push the car back, squeezing the belt with a screwdriver from the generator drive pulley.

We pull the new one onto the pulleys.

The installation takes place in the position of the generator when it is pressed against the engine. PHOTO: www.zr.ru

Engage fifth gear , push the car back, pressing the belt against pulley 1 in the picture. This is where a helper will come in handy.

As soon as we put it on, we work in reverse order:

• unplug the generator;
• press it into working position;
• return the upper mounting bolt and tighten the lower one.

Replacing the alternator belt on a Grant with air conditioning

It's more difficult here. Step by step :

1. we drive the car onto a lift or overpass;
2. remove the tensioner;
3. take off the front right wheel;
4. we support the internal combustion engine and dismantle the pillow;
5. change the required part.

The whole problem is in points 5 (air conditioning compressor clutch) and 7 (right engine mount) - our belt passes through them (number 6). The rest: 1-drive of auxiliary devices, 2/3-tensioner, 4-generator. PHOTO: www.zr.ru

What you need

• new belt marked 6РК 995;
• spanners 8, 19;
• socket wrenches 8, 10;
• Torx keys T20, T27;
• ratchet with extension and heads E14, 17.

Step 1. Tensioner

The car is on a lift or overpass.

The front right wheel studs are loose.

Open the hood. Remove the terminals from the battery.

We find the tensioner, take out the spanners 19 and 8:

1. 19 we put on the lead screw;
2. 8 hold the locknut;
3. we touch;
4. Turn the lead screw clockwise to loosen the tension.

We remove the lock nut and loosen the tension. PHOTO taken from: www.zr.ru

Step 2. Get under the car

You need keys 8, 10 . Filming:

• central shield (numbers 1, 5, 7);
• right shield (number 2).

Step 3. Wheel

Remove the front right wheel. Using keys 8, Torx t20, t27, we dismantle the fender liner according to the diagram.

To work with the fender liner you need three different keys. Having removed it, we gain access to the engine support. PHOTO: www.zr.ru

Step 4: Engine Mount

• Getting ready to remove the engine mount.
• We securely support the engine under the crankcase - the support should take the weight of the internal combustion engine.
• Using a wrench or ratchet with an E14 head, unscrew the screws securing the support to the engine .
• Use head 17 to unscrew the screws securing the support to the body.

We remove the support. Make sure the weight of the engine is securely supported in the crankcase!!! PHOTO: www.zr.ru

Step 5. Dismantling and installation

We remove the belt from the pulleys and rollers and pull it out.

install the new one in the reverse order.

Do not mix up the screws that secure the mount to the engine. The top one (included in the triangular part) is shorter than the bottom one!

Confusion is dangerous for the further operation of the machine. PHOTO: www.zr.ru

The final tension can be adjusted by adjusting the tensioner.

Instructions on how to assemble a tensioner on a grant

Any Grant has space for installing a tensioner. To assemble this you will need:

• generator bracket from Kalina;
• tension roller and its bracket;
• screw tensioner;
• new belt from Kalina;
• bushings and bolts.

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.

Let's summarize

To work with the generator and to replace the belt you need:

• set of spanners, Torx t20 and 27, ratchet with heads or wrench, knife;
• if there is no tensioner, you can assemble and install it;
• if there is no air conditioner, replacement is easiest;
• is there air conditioning? To work, you need a pit or a lift with dismantling the engine support;
• They change consumables every 30 thousand mileage according to regulations.

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.

Instructions for removing the generator

Let's start by describing the process of removing the generator from an eight-valve car that is not equipped with air conditioning. You need to start by disconnecting the “ground” from the battery, for which you remove the negative terminal (this manipulation must be carried out when removing this unit from any modification of the Grant, this will help to avoid a short circuit). Further actions are performed in the following order:

• the bolts on which the motor protection is attached are unscrewed, after which it is removed;
• disconnect the block with wires from the generator;
• after removing the protective cap of the nut holding the power drive, the nut itself is unscrewed and the wire is disconnected from the generator;
• then the upper mounting nut of the generator is unscrewed, and the unit is pressed out using a mounting spatula, and the upper mounting bolt is also removed at the same time;
• the lower fastening nut is unscrewed, the generator is carefully moved away from the engine, and the fastening bolt located below is pulled out;
• the generator is shifted to the right mudguard, the belt is removed from its pulley, the generator itself is pulled out;
• The process is completed by removing the belt from the crankshaft pulley.

Now let's look at a similar process carried out on a sixteen-valve Grant without air conditioning. Such machines are equipped with belt tensioners, and therefore the work described has some differences. So:

• First, the mounting bolts are unscrewed and the block is disconnected from terminal “D”;
• then the cap covering the “B+” terminal is removed;
• then the nut holding the wire tip is unscrewed and the nut holding the tension bar is loosened;
• the adjusting bolt of the tension mechanism is turned counterclockwise, and at the same time the belt tension is loosened with a 10 key;
• the generator is moved towards the motor, and the belt is removed from the pulleys;
• then the tension mechanism adjustment bolt is unscrewed and removed, and the tension bar is dismantled;
• the fastening nut located at the bottom is unscrewed;
• the spacer sleeve is removed, after which the mounting bolt located at the bottom is removed out;
• Finally, remove the tension bar and remove the generator out.

Now let's move on to describing the process of removing the generator from a car equipped with air conditioning. Since the air conditioning devices installed on Grants operate from the generator belt, they must be carefully moved to the side, after which you can proceed directly to the removal itself.

To successfully carry out this procedure, you must sequentially perform the following steps:

• to begin with, all the bolts that hold the cushions and bracket are treated with WD-40;
• then the mounting bolts are unscrewed and the protection is dismantled;
• after the WD-40 starts to work, unscrew the bracket nut;
• the jack is installed in front of the car, on the right, while the bolts holding its right front wheel are loosened;
• lift the jack, while hanging the wheel, and then remove it from the car;
• Next, the tension roller is dismantled, then the bolts that secure the pillow are unscrewed;
• the car is carefully lowered, hanging it (thus, the cushion moves towards the motor, opening a direct path to the generator).

At the final stage of work, you will need to remove the generator using one of the methods described above.

Replacing the Lada Granta generator - KZATE with Bosch. Comparative characteristics and disadvantages

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.
