What are the functions of transmission oil?
The type of fluid under consideration is intended for surface treatment of gearbox elements, including gearboxes, transfer cases, gears, and other parts. The main function of gear oil is to create a strong film on the surface of mechanisms. The composition of the liquid contains a large number of various additives, due to which the oil has great functionality and allows the treated parts to maintain their performance longer.
Reasons for replacing transmission oil
Over time, even gear oils bought at a high price lose their original properties. To avoid malfunctions in the functioning of the box, as well as wear and tear of parts, the motorist should worry about changing the oil in a timely manner.
The main reason that affects the urgent replacement of fluid in the transmission may be one of the following circumstances:
- violations in the operation of the gearbox, as well as gears;
- the presence of debris and dirt;
- the appearance of noise or clatter in the checkpoint;
- the appearance of soot on the parts (in this case, you should not just change the oil, but think about buying a liquid from another manufacturer);
- Difficulties in shifting gears during temperature changes;
- appearance of corrosion on parts.
Terms and conditions of storage of gear oil
Each oil has its own components in the composition, on which the operating time of the liquid depends. The shelf life of gear oil must be indicated by the manufacturer on the packaging. In most cases, oils containing good additives can be stored for 5 years without losing their original characteristics.
The rules for storing gear oil include the following points:
- Eliminate exposure to sunlight.
- Use only original packaging for storage.
- Compliance with the optimal temperature regime.
- Tight container closure.
It is necessary to check the oil poured into the gearbox monthly, because burnt additives can harm parts and mechanisms. If signs of bad oil are found, the fluid should be changed immediately. As for the expiration dates of motor oils, they are similar to transmission oils.
