1.3. Acquisition of spare parts

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

As a whole, accessible spare parts can be subdivided on two big groups:

Original spare parts. The given spare parts extend through official representations of the companies-manufacturers of cars, always have original packing and corresponding marks. Thus quality of a detail is guaranteed by manufacturers of the car. In the firm services-centres it is possible to get any spare parts which are let out for sold models. If what or the detail at the moment of centre visiting is absent, it in short terms can be delivered from the central warehouse.

Stereotyped spare parts. Definition "stereotyped" speaks nothing about quality of a detail. It means only that it is on sale not in firm packing of the company-manufacturer of the car and extend not through official representations of the company. The basic skeleton of sources of the given group is made by the known firms-manufacturers of spare parts delivering to a detail on assembly lines at times at once of several automobile factories. In a kind of high capacity of the manufacture such firms provide also delivery of spare parts for sale in the free market. Such details have packing and marks of the manufacturer spare parts, at all do not concede on quality to original spare parts at much lower cost. However, the assortment is usually a little more modest whereas for free sale usually try to let out only the most running details using the greatest demand.

Many large western dealers spare parts use own packing, buying the big assortment of stereotyped details in large lots is direct at manufacturers and selling them under own trade mark.

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

It is necessary to give special attention to quality of got spare parts. Try to avoid purchase of absolutely cheap details (in comparison with original and stereotyped known firms) as frequently they do not correspond to norms of quality and safety. If installation second-grade decorative молдинга is capable to affect negatively only appearance of the car use low-standard brake kolodok/the oil filter bears threat of safety of passengers, or can cause a serious damage to the engine. Thus expenses for regenerative repair by time many times over exceed saved at purchase of a cheap detail the sum. Told means that it is necessary to try to use official representations 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, thus the old, failed detail usually surrenders in exchange for the restored. The given approach is most productive at replacement of such difficult, expensive components as knots of the power unit, the generator, a starter, etc. Marked service is given both the firm services-centres of the company-manufacturer of the car, and independent suppliers of spare parts and allows to cut down essentially expenses on car repairs. Thus the firm offering the restored unit, usually gives on it almost same guarantee, as on the new.
