Why slip the clutch on the VAZ-2107?
The problem with slipping clutch on cars, which are usually attributed to the domestic classics, is fairly well known. This defect causes not only serious inconvenience in driving the car, but also entails unplanned financial losses. Slippage of the clutch leads to a fairly rapid failure of the squeeze bearings, wear of the discs and the combustion of the entire basket as a whole. This article is designed to answer the questions: why slips the grip and what should be done in this or that particular case?
How to determine this defect?
Slippage of the clutch can be easily identified independently, without the use of special equipment.
- Start the engine;
- Enable neutral transmission;
- Tighten the hand brake;
- Press the accelerator pedal;
- Squeeze out the clutch;
- Go to the first speed;
- Release the clutch pedal.
By all rules, as a result of these manipulations, the engine must eventually die out. If this does not happen, the motor continues to work, and there are extraneous sounds or the smell of burning, which means that the clutch slips and measures for its repair should be taken immediately. This is caused not only by financial reasons, but also by considerations of one's own security.
Reasons for clutch slippage
There are several reasons for this effect. As a rule, they arise because of the characteristic style of driving, which is usually called sporty. Sharp acceleration and braking, frequent shifting significantly reduces the service life of the clutch, although AvtoVAZ determines it in 75-85 thousand kilometers. In addition, experts argue that the performance of the clutch car can significantly affect the use of trailers. It is believed that they are able to significantly reduce the life cycle of the nodes and mechanisms of the automotive element. Consider the most common actual causes of clutch slippage.
Oil Contact
Often, if the clutch slips, the reasons for this lie in the ingress of oil or other technical fluid into the basket. The oil gets on the surface of the release disc, flywheel or on the lining of the driven disc due to the leakage of the rear seal of the knee shaft. Often the cause of leaks is the excess oil level in the gearbox housing. In these cases, if the clutch slips, the VAZ-2107 is repaired very simply. It will be enough to eliminate the cause of leaks and clean up those parts of the system that have been contaminated with oil. This can be done with the help of white spirit or gasoline. In the case of liquid on the friction pads, they also have to be cleaned with fine-grained sandpaper.
Depreciation of the disc linings
Friction linings disks have the property of being erased over time.
Damaged spring
Another reason for slipping clutch can be a failure of the pressure spring.
No clearances in the shutdown drive
Another fairly common reason why slippage slips (VAZ-2107 is or 2105, it does not matter) is the incorrect operation of its drive. Most often this is due to the fact that the necessary clearance of the clutch release actuator is simply missing. This problem can be easily eliminated by adjusting to the required values.
The pedal free play is insufficient
Often skidding clutch (VAZ-2107 often this sin) and because the pedal is too small free stroke.
There are other reasons, because of which skips the coupling of VAZs of any model, and the "Seven" in particular.
- Separation of the friction lining. The lining itself may not have visible damage or burnt areas. But as a result of the detachment, it ceases to perceive the load with its entire surface, which leads to slippage.
- Overheating of the squeeze disk. As a result of exceeding the temperature values of the maximum possible heat-absorbing characteristics of the clutch disk, its permanent expansion occurs, which causes the effect of slippage. Of course, this defect can not be established on the fly. But you can easily determine it by the characteristic burning and scum deposit on the disc itself.
This article lists the main reasons why slippage on the domestic classics and many other models of cars and trucks slips. It is important to remember that, whatever the reason for the clutch slip, it is necessary to eliminate it at the first appearance of symptoms of the defect. It is most expedient to entrust such work to highly qualified specialists.
In addition, with repair work performed independently, there is a high risk of disrupting the correct settings and adjustments, which will turn the replacement of parts into Sisyphean labor. Very soon, the clutch will again begin to stall, make a rattle and crackle, and the smell of superheated discs and linings will be clearly felt in the car's interior.
