Lada Granta generator: which one is installed and do-it-yourself replacement

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.

Alternative belt replacement options

Insufficient tension creates less inconvenience than constriction. The latter provokes too rapid wear of the bearings. To avoid such a problem, many Grant owners install the tensioner themselves: a part from the Lada Kalina is perfect for this.

The manufacturer does not initially install the part at the factory, since it positions Granta as the most affordable in its class, hence the savings on components. This is typical for the cheapest models with an 8-valve power unit.

To adjust the belt tension, you can use a bracket from Kalina, modifying it a little with your own hands. To do this you will need the following set:

• bracket;
• tensioner;
• roller bracket;
• alternator belt from Kalina 1;
• screw tensioner.

Thanks to this kit, you can significantly improve the design of your car, extending the service life of some parts and components.

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.

Overrunning clutch

An overrunning clutch is a mechanism that prevents the transmission of torque from the driven shaft to the drive shaft when the first one rotates too quickly. Does Grant need to be equipped with such a device? Let's try to figure it out.

As you know, the engine produces torque in jerks - when the fuel mixture is burned, the crankshaft begins to rotate rapidly, after which it slows down. Also, accelerated wear is caused by the generator itself, which is caused by the inert rotation of the armature. As a result, the belt is exposed to constant pulling forces, which significantly reduces its service life. To prevent such phenomena, overrunning clutches are installed. Its advantages include the ability to significantly reduce the negative inertial influence and ensure silence and a minimum of vibrations during engine operation.

The installation process is simple. First, remove the generator itself (according to the instructions above), after which the generator pulley is removed. To do this, fix the pulley with an adjustable wrench, and then unscrew the nut with a 24mm wrench.

Then install the coupling, having previously treated the threads and seat with graphite lubricant. Having installed the part in its proper place, tighten the nut with a special wrench. The installation of the generator completes the work. The entire replacement process takes approximately one and a half hours.

Signs of generator malfunction, ways to eliminate them

general information

The generator is designed to transform the mechanical energy received from the crankshaft into electrical energy. It is also designed to charge the battery, while simultaneously acting as a power source for all electrical equipment of the car.

This unit consists of a pulley, a casing, a coupling bolt, a terminal on “B+” and a connector “L”, as well as front and rear covers. Each generator is equipped with a diode bridge and a voltage regulation unit operating in parallel with the battery. It is thanks to these elements that the alternating current is converted into direct current, and at the output the electric current receives the required voltage.

The main components of the generator include a stationary stator and a rotor, which is driven by the crankshaft. The rotor is separated from the stator by a layer of air, their main working elements include the winding and magnetic circuit, all other elements are designed to provide the required level of rigidity, cooling, etc. The stator is fixed on the generator cover, the back of the cover is covered with a plastic casing, and the rotor shaft rotates at 2 installed in bearing caps. The stator includes three-phase windings connected to the rectifier block, and the diodes are pressed into 2 horseshoe-shaped holders.

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.

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.

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.

Write comments and share your experience.

The “Grants” generator has to be removed for various reasons: for repair, maintenance, modification of the unit. You can do this yourself if you know how to remove the generator on the Grant. Depending on the modification of the car (8 or 16 valve engine, presence of air conditioning), the procedure for dismantling the generator has its own characteristics, so it is worth considering each option separately.

Inspecting the old belt

The manufacturer recommends checking the condition of the alternator belt every fifteen thousand kilometers. And every thirty thousand you need to change the belt, even if you are completely satisfied with its appearance.

As for emergency cases of replacing the alternator belt, they occur when you have inspected it and noticed damage on the surface.

Among the main types of damage are abrasions, cracks, detachment of rubber from a base made of fabric, and so on. If the belt has at least some flaws, this means it needs to be replaced.
