As you know, the work of the belt drive allows the car generator to convert energy, creating an electric charge. If any item fails, the generator can no longer function normally.
This is especially true for the belt. On VAZ 2112 Replacing the generator belt is an important procedure that takes place every 10 thousand km of run. Replacing the VAZ 2112 generator belt can be carried out on its own.
As mentioned above, the item must be changed in a timely manner, and not to avoid problems. The main feature of the failure of the generator belt is the cracks that the driver of the vehicle is obliged to notice.
Note. The instruction of the car manufacturer recommends changing the belt every 45 thousand km, but in practice it is not. Poor road conditions, improper initial driving manner and much more negatively affects this item. Therefore, 10,000 km. The run is a feature that in practice determines the replacement time.
Replacement without gur
As a rule, it is customary to share instructions for software. If the car without GUR, then the step-by-step instruction for replacing will look like this.
First you need to check the tension to determine the degree of wear. A normal belt, naturally non-cracking, should be fed by 10 or 15 mm if an effort is acting equal to 100 H or 10 kgf.
The effort must be made exactly in the middle, right between the generator and the crankshaft pulley. If the tension is weak or vice versa tight, you need to either adjust the part or replace it.
Replacement algorithm
So:
- Raise the front of the car;
- Remove the protection of the crankcase;
- Weakening the tightening of nuts that lock the upper and lower fastening of the generator;
- Turn the adjusting bolt (we do it for the maximum possible value);
- Old belt dismantle.
Note. You need to remove the part by making the generator to the cylinder block as close as possible.
- We put on a new belt on and crankshaft;
- Then adjust the tension.
Replacement with gur and air conditioning
If the change of the generator belt on the car without GUR takes only ten minutes, then vice versa, in the case of the GUR or air conditioning, as on the prior, the procedure is noticeably complicated.
The fact is that if the car is installed on the car, then the location of the generator is already in another place. In the same native position there is a pump GUR. The generator itself is moved in this case above.
In addition, the location of the generator is changed on cars with air conditioning and Gur, the belt itself also passes another axis. In this case, the detail first passes the crankshaft pulley, then the tensioning roller, the generator shaft, the pump shaft and again the crankshaft pulley.
Note. The replacement procedure on the car with GUR complicated by the fact that the belt rotates around the left operator of the motor. Thereby, to replace the item, the engine should be lifted, and then the chain is then removed.
We will proceed to the replacement procedure:
- The generator belt to start weakening;
- Remove.
Note. The bolt of this very support in theory should fall down after unscrewing, but it is possible that it will strive with a hat into the pulley GUR. If this happens, nothing terrible. It will be necessary to unscrew the pulley of the GUR, then unscrew the 3 bolts, remove the pulley and pull out the bolt.
- We raise the engine using a bottle jack (it should be installed through the hole for the oil drain, and under the edge put a wooden bar, so as not to remember the edge of the crankcase);
- Remove the protection of the crankcase;
- I pull the support nut now;
- Patch the generator belt through support;
- Remove the item.
Installing a new part is carried out in the same sequence. But before buying a new belt, you should know that the item must have 6 streams.
In addition, the length of the generator belt must be exactly 1115 mm. If there is no such chain on sale, it is recommended to install the strap priors with air conditioning.
Tension
After installing the new belt or in general, the part may need the right tension during operation. As it was mentioned above, poor tension leads to various problems in the functioning of the car.
Simple tension without gur
So:
- The generator is assigned from as far as possible;
- Adjusting bolt rotate clockwise - the belt is stretched;
- If we want to weaken - rotate the adjusting bolt counterclockwise;
- The crankshaft turn over the fastening bolt for 2 turns;
- We again check the tension (if necessary, the adjustment is proceeded).
Tension from gur.
As in the case of replacement, the tension of the generator belt on cars with GUR is different. The point again is that the angle of girth of the pulley belt is rather small.
If you pull it simply, as in the first case, it will slip. To this end, the tension is carried out more, as it is indicated in the car instructions from the GUR.
The above step-by-step instruction will help everything successfully with your own hands. It does not prevent in the process of work. See photos or video - materials as examples of visual benefits.
The price of replacing the generator belt in the hundred is quite high, so there is no need to pay extra money.
