How to change the belt tensioner pulley of a grant generator with air conditioning

The generator belt tensioner roller (hereinafter referred to as NR) on the Lada Grant is installed exclusively in the “Lux” configuration with a 16-valve engine. Budget 8-valve versions of Lada Granta: “Norma” and “Standard” do not have a roller in the standard design.

Violation of the belt tension moment leads to its breakage. Many car owners determine the tension “by eye,” which in most cases is incorrect.

In service stations, special devices are used for these purposes, for example, a multimeter. Which allows you to adjust the tension using the voltage indication at the “output” from the battery.

In order to prevent belt breaks and deformation, many motorists install a tension roller. The same one that is built into the “Lux” package by default.

Let’s look at how to do this on budget Lada Granta models and what is needed for this in detail using the example of the Lada Granta “Norma” and “Standard”.

Detailed guide to replacing the alternator belt on a Grant with air conditioning

Power for the vehicle's electrical equipment while driving is provided by a generator, which operates thanks to a belt drive. Therefore, the effective operation of the unit depends on the condition of the belt. This is a consumable item that requires regular replacement. The article provides instructions on how to check and replace the belt on a Grant alternator with air conditioning.

Conclusion

The factor of defects in the manufacture of parts cannot be excluded, but much also depends on the owner of the car. Maintenance deadlines are often missed. Drivers save on maintenance and buy cheap spare parts that are not even covered by a warranty.

Those who adhere to the manufacturer's basic maintenance rules drive more than 35,000 km without accidents before replacement.

The process of replacing the alternator belt tensioner roller yourself is not complicated, but requires care.

Technical regulations for Lada Granta cars

In order to be sure that the car will not fail on the road, you should monitor its technical condition and comply with technical regulations. Maintenance consists of diagnosing vehicle systems and components, identifying and troubleshooting problems. But even if everything is in order with the car, it is necessary to carry out the routine operations provided for in the vehicle’s operating manual.

Experts recommend doing a technical inspection when purchasing a used car and every 15 kilometers. During a visual inspection, you should check the systems and components for leaks, check the reliability of fasteners, the generator voltage regulator, belt tension, and their condition. If necessary, change filters, oils, working fluids, and consumables. In order to bring the car into good working order, you need to buy all the necessary consumables in advance so that they can be replaced during inspection.

The accessory strap is a consumable item that needs to be replaced periodically. In the Lada Granta manual, the manufacturer recommends replacing the belt every 30 thousand km. Experienced drivers advise checking the condition of the belt drive at intervals of 15 thousand km.

The frequency of replacement of consumables is influenced by the following factors:

• terms of Use;
• driver's driving style;
• quality of consumables;
• serviceability of components and mechanisms;
• climatic conditions.

If the machine is operated in difficult conditions, then diagnostics should be done more often. It is recommended to do a technical inspection before a long trip so that the car does not fail along the way.

Self-check the condition of the alternator belt

Before replacing an implement belt, drivers should perform a visual inspection to determine if replacement is necessary. To perform diagnostics, the vehicle must be stationary. To prevent the car from rolling during inspection, clamps should be installed under the wheels. The generator belt is located in the engine compartment, and is tensioned on the pulleys of the attachment.

The entire product must be checked. Having examined one area, inspect all the others sequentially, turning the belt. You can make a mark at the place where the inspection began.

The following signs indicate the need for replacement:

• cracks and abrasions on the surface, both internal and external;
• frayed, sides;
• peeling of rubber from rubber;
• mechanical damage;
• traces of oil and working fluids are on the surface.

During inspection, you also need to check the belt tension. If it is loosely tensioned, the generator will not work at full capacity. Too much tension causes premature wear of the bearings and strap. To check the tension, press the belt in a place free from equipment. With a force of approximately 10 kg, the deflection should not be more than 7-8 cm.

If the tension is insufficient, then you need to know how to tighten the belt. The tensioner screw acts as a regulator; it is used to perform tension (video author – Remgar).

When replacing a belt, it is advisable to change the tensioner pulley, which should also be inspected. It should be free of scratches, chips, play, and deformation. The roller should rotate freely without delay. You should not neglect regularly checking the condition of the belt drive.

Which kit to buy

In addition to the toothed belt, a tension roller and a coolant pump are purchased. The main supplier of rubber products is the RTI plant in Balakovo. Products from GATES, BOSCH, DAYCO, CONTITECH have proven themselves well. If the pump in the engine cooling system is replaced, antifreeze will be needed to top it up.

The gas distribution mechanism is one of the most important systems of an internal combustion engine. The timing belt controls the engine valves, ensuring the normal functioning of intake and exhaust. During intake, the fuel-air mixture enters the combustion chambers as a result of the opening of the intake valve. The next phase opens the exhaust valve, and the gas distribution mechanism removes exhaust gases from the combustion chamber. The VAZ 2190 uses a standard gas distribution unit, differing only in the number of engine valves.

DIY replacement instructions

A Lada Granta 8-valve car requires replacement of the alternator belt in the same way as a 16-valve car after identifying defects or according to the regulations. The procedure can be performed by a driver who does not have much experience in repair work. It is enough to have the necessary tools and basic knowledge of where the components that require replacement are located.

Tools and materials

Before replacing, you need to purchase a new alternator belt. In order not to make a mistake with your choice, you should look at the catalog number in the operating instructions. It should be 1118-1041020-07. The size should be 823 mm.

You should buy originals so as not to buy a fake or low-quality product. The packaging should be marked 6РК 823. You should not save money by buying a cheaper product. A low-quality belt will not last long, and the consumables will have to be changed earlier than required by regulations. High-quality belts are produced by Bosch and Gates.

You should also buy a tensioner pulley if you decide to change it too.

In addition to consumables, you need to prepare the following tools:

• a set of keys;
• TORX E-14 head;
• long screwdriver;
• jack;
• emphasis

Stages

The procedure for replacing the generator set belt on a Lada Granta with air conditioning is complicated by the fact that the belt passes through the support of the power unit. Therefore, before putting on a new strap, it will have to be dismantled.

Replacement consists of the following steps:

1. First, using a “19” wrench, you need to loosen the lock nut of the strap tensioner lead screw. While unscrewing the locknut, hold the screw with the head at “8”.
2. To loosen the belt tension, rotate the lead screw in the direction of movement clockwise. By following these steps, you can adjust the tension of the accessory drive belt.
3. To replace the strap, you need to remove the right engine mount.
4. Having moved under the car, you need to dismantle the right and middle protective shields of the engine compartment.
5. Then unscrew the fastenings in the middle and front part of the right front wheel arch liner. Next, bend the fender liner behind the wheel brake disc.
6. Using a jack, we hang the right front wheel and dismantle it. The fender liner fastenings can now be released.
7. At the next stage, we place a stop under the oil pan of the power unit so that it holds the weight of the engine.
8. Using a TORX E-14 head, unscrew the screws that secure the support to the cylinder block bracket of the power unit. Using the “17” socket, unscrew the two nuts and the support bolt that secures it to the body side member.
9. We dismantle the engine mount with the cushion.
10. Now, through the resulting opening, you can remove the strap from the pulleys of the auxiliary units and pull it out of the engine compartment.
11. We install a new consumable in place of the worn-out product. In this case, its tension should be adjusted using the tensioner screw. The deflection of the belt in the gap between the air conditioner compressor and the power unit pulley with a force of 10 kilograms should be within 7-8 mm.
12. We perform assembly in the reverse order of removal.

This completes the replacement. Now you know how to replace and tighten the generator set belt on a Lada Granta.

Procedure for independently replacing the alternator belt roller on a Lada Grant

Necessary tools, materials:

• set of car keys, sockets, ratchet;
• rags, liquid WD – 40;
• new HP;
• graphite-based lubricant;
• additional lighting.

We begin work after the engine has cooled down, the temperature is safe, which eliminates burns and injuries.

1. We place the car on a flat platform, maybe an inspection hole.
2. We open the hood, “reset” the battery terminals to avoid a short circuit in the circuit.
3. Using a key set to “13”, loosen the tensioner locknut, pry it off, and remove the generator belt.

Removing the belt

Loosen the locknut

1. Using a “10” socket, unscrew the three screws and remove the HP mount assembly.

Note to the driver. Not all motorists and mechanics agree with the above method, as they consider it labor-intensive. Instead, unscrew the central nut - the roller lock.

In part, the above method is less expensive, however, the fact that the fastening may be damaged or deformed is not taken into account. In this case, it must be replaced.

Removing the HP mount

1. We remove the HP assembly, carry out troubleshooting, inspect the mounting location and roller bearings.

At this stage, it is important to identify possible damage to the fastening. If there are any, then the part must be replaced, otherwise we install only a new roller with a rolling bearing inside.

1. We install and screw the HP assembly, put on the belt, and adjust the degree of tension.

1. We start the engine and check that the mechanism is working properly.
