How to remove the grant generator bracket 16 valve

Lada Granta cars, like other vehicles, are equipped with a generator designed to power electrical equipment components while driving. If there are malfunctions in the operation of this device, first of all the driver pays attention to the condition of the belt. Below we will talk about how to replace the alternator belt on a Lada Granta car with air conditioning.

Technical regulations Lada Granta

If you decide to change the belt or belt tensioner of the alternator (RG) on a Grant with an 8-valve engine, you must follow the technical regulations of the manufacturer. According to these data, the Lada Granda alternator belt should be checked every fifteen thousand kilometers. And every 30 thousand kilometers a replacement procedure must be carried out.

In other words, the owner of an 8- or 16-valve Grant must carry out a diagnostic or replacement cycle every 15 thousand km. And if we take into account that a tensioning device, as such, is not used, then the RG is completely intended for one-time stretching during its installation. Of course, you can tighten the replaced RG on an 8-valve engine, but the manufacturer does not recommend this.

Most common faults

During operation, the surface of the roller is constantly in contact with the generator belt. In addition, it is in continuous rotation, which places additional demands on the reliability of its bearings. The tensioner bracket is also subject to heavy load. Hence the main problems:

• Bearing wear. It simply runs out of service life or becomes unusable due to dust and dirt getting on it.
• Damage to the work surface. As already mentioned, the roller itself is made of plastic. Despite its high wear resistance, it often cannot withstand loads. This manifests itself in the form of scratches and chips, which quickly render the alternator belt unusable.
• Misalignment. This means that the belt and tensioner are at a certain angle to each other. Alignment can be disrupted in both the horizontal and vertical planes (due to the curvature of the bracket). This always causes rapid wear of the belt and the roller itself.

Often the cause of the malfunction is the driver himself. When trying to make adjustments, he forgets or does not loosen the locknut enough. As a result, the hexagon of the stud breaks off, and the Kalina generator belt tensioner fails.

We check the condition of the alternator belt ourselves

Before replacing the Lada Granta alternator belt, car enthusiasts usually check its condition to make sure whether this is really necessary. To diagnose, you need to follow simple steps. First, you need to engage fifth gear and get out of the car, and then try to push your Grant back, working on the front bumper or side pillar, if an assistant does this. In this case, the hood must be open and while pushing it is necessary to see how the RG behaves.

Worn and damaged RG, unsuitable for use

There should be no signs of damage on the strap when pushing the car. We are talking about cracks, delamination or breaks, even the most minimal ones, although this is quite possible, especially if the vehicle is used frequently. If during the diagnostics you notice traces of damage on the RG, this indicates that it will not be possible to tighten the belt - it needs to be replaced. The timing belt is diagnosed in a similar way.

If you don’t need to tighten the RG and adjust the tension on an 8-valve engine, you can also check the condition of the generator itself. After all, if you have any suspicions about the quality of the work of the DG, it makes sense to check the device itself. In addition, during diagnostics, you can also check the generator belt tensioner pulley, with which the belt can be tensioned. If there are chips on the roller or other signs of deformation and damage, including changes in geometry, the element must also be replaced. The video below provides detailed instructions for replacing the bracket, as well as the alternator strap on a Lada Granta car (the author of the video is Igor Semenishin).

Rotor and stator repair

First of all, you will need to examine the stator and rotor windings for breaks. To do this, you do not need to remove the generator from the car. It will be necessary to dismantle only its diode bridge. This will require a two- or three-jaw puller, as well as an artificial frame borrowed from a cup puller.

Replacing unit parts

Carefully straighten the wires in the winding and remove the diode bridge. To avoid getting confused during reassembly, you need to mark with a marker the placement points of the front and rear casing of the generator. Using a size 8 socket wrench, unscrew the 4 bolts that hold both trims in place. Carefully remove the front trim using a flathead screwdriver. After this, slide the rear casing and remove the connecting bolt along with the insulating washer, as well as the plastic plug from the bearing.

To check you will need an ohmmeter tester. Having connected its plugs to the rotor rings, check the winding for breaks. In this case, the winding resistance should be 5-10 Ohms. After this, connect the tester plugs to any of the slip rings and to the rotor. Now you need to check the winding for short breaks to ground. If the winding has no breaks and is working correctly, the tester will show the highest resistance value.

Replacement instructions

The procedure for replacing the RG is quite complicated and responsible. If you make a mistake during the steps, this may lead to the strap breaking while the car is moving. Of course, it will be possible to continue driving to the nearest service station or garage, but you will lose not only the money spent on the purchase of the RG, but also your own time. Therefore, think several times before whether you can do everything yourself and whether it is advisable - perhaps it makes sense to simply pay specialists at the service station. But at the same time, you will be sure that everything was done correctly, and if problems arise, you will have someone to file a claim with.

Tools and materials

So, if you decide to replace the cylinder head on an 8-valve engine yourself, below you will find instructions on how to complete this process. In order to do everything yourself, prepare the strap itself. There is one more point here - the purchase of all parts and consumables for repairing an 8- or 16-valve engine must be carried out from representatives of an official dealer. Today the cost of such a RG is around 12-15 dollars or 700-1000 rubles.

Recommendations for the selection of parts and components

In the absence of external mechanical damage, the service life of the brackets is unlimited. In practice, manufacturers set a maximum warranty period of 100,000 km.

Regardless of the modification or type of bracket, purchase only original parts with factory catalog numbers.

Save money or buy fasteners from Lada Kalina - this is the choice car owners face. The difference in the cost of parts is 350 – 450 rubles. The final choice is up to the driver.

The expert's advice is to buy fasteners from Lada Kalina.

Video “Detailed instructions for replacing the RG on a Lada Granta car”

You can learn how to properly replace the strap on the domestic Lada Grant from the video below (the author of the video is MR. BORODA).

On cars of the Lada Granta family with 8-valve engines, an automatic alternator belt tensioner is not pre-installed. Engine modifications are as follows: VAZ-11183, VAZ-21116, VAZ-11186.

You can compensate for the lack of a tensioner in different ways:

• monthly check of the tension level of the converter drive, which is impractical and costly;
• replacing the standard KATEK generator with a Bosch: not every car owner will afford to purchase an imported converter;
• systematic “updating” of the generator bearings: excessive tension of the drive belt, the absence of an automatic tensioner in the design creates the preconditions for premature wear of the bearings;
• set the fastening bolt with a diameter of “6.0” instead of “10.0”, which will increase the free play of the converter by a few millimeters to adjust the tension;
• “makeshift” modification of the standard bracket for the Lada Granta generator;
• replacing the Lada Granta generator bracket with the Kalina bracket.

Each of the above methods has its own advantages and disadvantages. Let's consider the last two options for “modernization” as the most common.

Forced tuning

Unfortunately, since 2011, designers have abolished the tensioner on Kalina. They were guided primarily by considerations of economy, but they did this without any modification to the generator. In practice, cases of its premature failure immediately became more frequent. Therefore, owners began to install the tensioner on their cars themselves.

It's not very difficult to do this. True, you will have to purchase not only the tensioner itself, but also the generator bracket. The only problem is removing the standard belt. It is very difficult to remove because it is very tight at the factory. You can simply cut it, as you will have to buy a new one. The fact is that the Kalina generator belt without a tensioner has a size of 820 mm, but 880 will be needed.

Preparatory stage before modifying the Lada Granta generator belt bracket

Necessary tools, materials:

• a set of car keys, sockets, ratchet, screwdriver with a flat, cross-shaped bit;
• rags;
• liquid for removing deposits and rust WD-40;
• hammer, drill, metal drill bit for “6”, “8”, “10”;
• graphite-based lubricant;
• additional lighting, since visibility in the engine compartment is limited;
• metal mounting;
• torque wrench;
• bolt with a diameter of "8", length 100 - 110 mm.

Step-by-step instructions for removing the generator from a Lada Granta car

Before altering the mount, we remove the converter from its standard place in the engine compartment. To do this, perform the following steps:

1. We place the car within the perimeter of the repair area, provide safety measures, and secure the rear row of wheels with wheel chocks. Additionally, squeeze the parking brake lever.
2. Open the hood and disconnect the terminals from the battery to prevent a short circuit in the circuit.

Accumulator battery

1. We unscrew 6 bolts under the bottom of the car and temporarily remove the oil pan protection.
2. Remove the protective cap and terminals from the contact board on the converter.

Removes clamps

1. We unscrew the nut of the upper fastening (key set to “13”), and use the mounting tool to move the converter to the side. Unscrew the lower mounting bolt.

Unscrew the nut and bolt

1. We remove the generator belt from the pulleys.
2. We remove the converter assembly and fix it on the surface of the workbench.

Sequence of actions when modifying the generator bracket with your own hands on the Lada Grant

1. We grind 2 - 3 cm on each side of the generator mount. It is better to do this in a stationary vice using drilling equipment. Due to the lack of equipment, we use a grinding machine, which is known as a “grinder”.

Sew 2-3cm on each side

1. Using a drill with a metal drill (at “8”), we drill out the standard hole on the mount, making the stroke length for the bolt 1.5 - 2.0 cm.

Drill out the standard ring

1. Using a grinder, we partially grind down the stiffening rib on the mount so that it does not interfere with the free movement of the converter.

1. We cut out a corner of metal 40 mm long and 30 - 40 mm thick, and bend the edge. It turned out to be something like the letter “G”. One end is attached to the bracket, on the other we weld a nut to “10”.

Corner letter G

1. We assemble the structural elements, screw in the bolt to tension the generator drive belt.
2. We install the converter and the bracket without tensioner in its original place.
3. We move the rocker to the third gear position, put on the drive belt, and turn the crankshaft pulley by hand.
4. Check the degree of belt tension.

Belt tension level
At home, we check the tension level of the generator drive belt as follows. Using your finger, press on the section of the belt between the crankshaft pulley and the tensioner. The belt bends by 10 - 12 mm, no more. Tighten the fastening (tension) as necessary.

Finally, we start the engine and check the functionality of the system.

Adjustment methods

Currently, there are three main methods of tensioning the alternator belt in cars:

1. Using a special arc-shaped strip. In this case, the generator has two mounting points. One of them is an axis around which it can move within small limits. The other is the nut on the adjustment bar. If you release it, you can move the pulley to the required distance. This method is now considered obsolete. It is mainly used on VAZ classics.
2. The generator is moved by rotating the adjusting bolt. This system has become widespread in cars of the tenth family.
3. Using a tensioner. This is a special movable roller that rests on the belt between the generator and crankshaft pulleys. It is equipped with a screw mechanism. By rotating it, you can adjust the pressing force. This is exactly the kind of alternator belt tensioner for the Lada Kalina.

Replacing the generator bracket with tensioner on the Lada Grant from Lada Kalina

Despite the fact that the previous method is the most economical, it is time-consuming.

Many drivers prefer to pay an additional 350-450 rubles and purchase a ready-made kit for installing a bracket from the Lada Kalina to the Lada Granta.

The sequence of actions is as follows:

1. After dismantling the converter from its standard place in the engine compartment, we proceed to install the bracket from the Lada Kalina.

Original equipment of the modernized mount:

• belt;
• tensioner roller;
• bracket;
• axis to “10”;
• tensioner

1. We unscrew the three mounting screws from the old converter, remove the old bracket, install and screw the new one.
2. We fix the structure in its regular place, screw the three nuts to “13”.
3. We activate the rocker to the third gear position.
4. We put on the generator belt, turn the generator pulley by hand until the belt fits into the groove grooves.

We start the engine, check the charging and the LED indication on the dashboard.

Where is the standard generator located on a Lada Granta car?

Regardless of the modification of the Lada Grant, the converter is installed in the engine compartment on the left side, closer to the radiator of the cooling system.

The design of the Lada Granta’s engine compartment is not “entirely successful”; craftsmen have difficulty dismantling the equipment.

The difference between replacing the generator bracket in 16 and 8 valve engines

The brackets are identical in shape and number of fasteners. The difference is the absence of an automatic tensioner in the 8-valve engine modification.

The Lada Granta generator bracket with air conditioning is identical to the 16-valve modification of the engine.

Difference between belts of 16 and 8 valve engines

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

• 8 valves: 1118-1041020-07: 6РК 823, length 823 mm, thickness 3.0 mm;
• 16 valves: 6PK1123 with air conditioning, 6PK1113 with power steering, without air conditioning.

Signs of generator malfunction, methods for eliminating them

Generator disassembly and repair

Bracket for mounting the unit

Repair is carried out by dismantling the generator and voltage controller. Using a flat screwdriver, you need to hook the tips of the stator wires and slightly pull them out of the spring connections of the diode bridge of the generator. Using a 8mm spanner you need to unscrew the 3 bolts that secure the diode bridge. In this case, be sure to write down or remember the layout of the insulating and support washers. After this, you need to unscrew the screw of the connecting bolt using a 12mm wrench.

To determine the technical suitability of the rear bearing, you need to lightly shake it and twist the outer ring. If the bearing rotates easily, without stopping, and there is no noise or large play, then everything is fine with it. If at least one of the above deficiencies is detected, you will need to replace the bearing with a new one.

Proceed to dismantle the Kalina generator bracket. Having marked the required placement points with a marker, pick up the stator with a screwdriver and carefully remove it from the rear casing of the generator. The generator bracket includes a bearing, the technical suitability of which must be checked using the same method as described above. If any faults are found, it must be replaced.
