1.3. Acquisition of spare parts

An important role at repair work is played by use of spare parts and expendables only quality, intended for the concrete car.

In general, available spare parts can be subdivided into two big groups:

Original spare parts. These spare parts extend through official representative offices of the companies manufacturers of cars, always have original packing and the corresponding marking. At the same time quality of a detail is guaranteed by producers of the car. In company service centers it is possible to buy any spare parts released for the sold models. If any detail at the time of visit of the center is absent, it in short terms can be delivered from the central warehouse.

Stereotyped spare parts. Definition "stereotyped" tells nothing about quality of a detail. It means only that it is on sale not in company packing of the manufacturing company of the car and extend not through official representative offices. The main frame of sources of this group is made by the known manufacturing firms of spare parts delivering to a detail to assembly lines sometimes at once of several automobile plants. In a type of high power of the production such firms provide also delivery of spare parts for sale in the free market. Such details have packing and marking of the producer of the spare part, are not of a lower quality than original spare parts at much lower cost at all. However, the range is usually a little more modest in view of the fact that for free sale usually try to release only the most running, the details which are in the greatest demand.

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

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

Special attention should be paid to quality of the acquired spare parts. Try to avoid purchase of absolutely cheap details (in comparison with original and stereotyped well-known companies) as often they do not meet standards of quality and safety. If installation of a second-grade decorative molding is capable to affect negatively only appearance of the car, then use of low-standard brake blocks / an oil filter poses threat to security of passengers, or can cause serious damage to the engine. At the same time costs of recovery repair time many times over exceed the sum saved upon purchase of a cheap detail. Told means that it is necessary to try to use services of official representative offices of the company manufacturer of the car (original parts), or well proved suppliers of stereotyped spare parts.

There is also a possibility of acquisition of the restored details, at the same time the old, failed detail usually is given in exchange for restored. This approach is most productive when replacing such difficult, expensive components as knots of the power unit, the generator, a starter, etc. The marked service is provided both company service centers of the manufacturing company of the car, and independent suppliers of spare parts and allows to cut down significantly expenses on car repairs. At the same time the firm offering the restored unit usually gives on it almost same guarantee, as on new.
