Reasons for reducing the life of a mechanical transmission and clutch?

Manual transmissions are quite reliable. Moreover, after the “mechanics” has worked for more than 100,000 km, it is at risk of breakdowns.

Mechanical manual gearboxes are structurally simple, so there is nothing special to break here. This design can work under loads of at least 500,000 km in case of timely maintenance.

At the same time, the “mechanics” have two main problem areas. We are talking about synchronizers and a clutch unit that transmits torque from a running engine to the transmission. These technical elements largely depend on the accuracy of motorists, the level of their own training and the ability to sense the loads acting on the functioning friction discs.

Synchronizers fail due to improper transmission activation. According to the rules, motorists first of all need to press the clutch, and then set the selector to the position that is required. Then the pedal should slowly be returned to its original position, smoothly transferring the load from the power plant to the car transmission. Meanwhile, many beginners do not know how to dose the forces created on the pedals, closing the discs too quickly, allowing unwanted jerks in the running transmission. Shock loads eventually destroy the synchronizers.

The service life of gearboxes with special gear connections is affected by the frequency of fluid replacements. Already after the first repair work on an automobile clutch, experts advise replacing the technical fluid, since gear wear products accumulate inside the transmission. After that, technical fluid can be changed in a car after 60 thousand km. the path traveled.

The performance of functioning clutch units depends on the qualifications of motorists. The resource of this mechanism is reduced due to frequent participation in street races, forced slippage on dirt roads, abrupt breakdowns of cars from a place at high speeds of the installation, ingress of foreign objects / liquids, unskilled adjustment of the technical unit.

In conclusion, it is worth noting that another mistake is the systematic frequent pressing of the clutch pedal while driving. Drivers often forget to remove their foot from the clutch in time, as a result of which the resource of the mechanism is greatly reduced.
