Acquisition of spare parts

GENERAL INFORMATION

The important role at repair work is played by use of spare parts and the quality expendables intended for your car.

As a whole spare parts can be subdivided into two big groups:

Original spare parts. These spare parts extend through official representatives of producers of cars. They always have original packing and marking of the producer of the car. Quality corresponds to all requirements and is guaranteed by the producer of the car. The official representative of the producer of the car has in the range all spare parts for this car. If any detail is absent in a warehouse of the representative, it in short terms is delivered from the central warehouse.

Stereotyped spare parts.
Definition "stereotyped" speaks nothing about quality of spare parts. It means that they are on sale not in packing of the producer of the car and extend not through the official representatives trading in cars. The main frame of this group is made by the known firms producers of spare parts delivering details on assembly conveyors of automakers. As their equipment and technologies allow to make spare parts and for cars of many other producers, they let out details not only for the assembly conveyor any one or several autocollectors, but also for sale in the free market. These details have packing and marking of the producer of the spare part. Quality does not concede to original spare parts, and the prices can be much lower, than at original (the difference can reach 50 % in favor of stereotyped). The range is a little more modest, than at original spare parts. The program includes the details most running and using the greatest demand.

Many wholesale western merchants in spare parts use own packing, buying the big range of stereotyped spare parts in large lots directly from producers and selling them under own trademark.

Stereotyped spare parts, as a rule, extend through free shops of spare parts, free automobile repair shops and service stations.

It is necessary to give special attention to quality of acquired spare parts. It is necessary to avoid purchase of very cheap spare parts (in comparison with original and stereotyped known firms) as often they do not correspond to standards of quality and safety. If the decorative molding of poor quality negatively influences only appearance of the car, installation of bad quality brake shoes or the oil filter can become threat for safety of passengers or cause a huge damage to the engine so costs of repair many times over will exceed saved upon purchase of the cheap spare part the sum.
Therefore it is necessary to use or services of official representatives (original parts), or well proved sellers of stereotyped spare parts.

There is also a possibility of acquisition of the restored details, thus you return an old detail. It first of all belongs to difficult, expensive details, such as the engine, the generator, a starter etc. Such possibility sometimes offer both official representatives, and free sellers of spare parts.

It also saves some part of your means, in most cases quite essentially. Thus the firm selling the restored unit, gives on it almost same guarantee, as well as on the new.

Identification of spare parts

The producer of cars constantly improves the production, constantly making to a change design. Can happen so that within one series and one option of execution of the car some knots and units can differ slightly from each other, and the spare part from one, for example, earlier option will not be suitable for another. Therefore at acquisition of spare parts it is very important to provide to the seller the fullest information on the car. The more exact data on the car, you will provide, the it is less probability of a mistake.

Besides the standard data set, including year of release, body type, option of execution of a body, number the chassis (number VIN), engine number etc., the seller can interest the following data:

Whether any additional equipment (for example, an additional heater, more powerful generator, the conditioner) is established on the car.

Transmission type.

Whether there is a catalytic converter?

Type of system of injection of fuel etc.

Detail installation site.

If for any reason the documents reflecting these data, no, it is recommended to consult about it at experts, for example, having called in in the firm center.

Sometimes, buying this or that spare part, happens it is very useful to take with itself an old detail subject to replacement for comparison.
