- Cast b/u drives.
To check b/cast wheels and drove them to the nearest tire. Ask the employees of the tire to remove rubber disc, if there's any on them.
Explain to the employees of the tire that you need to check the disk geometry. Employees of the tire will inspect your alloy rims on a normal balancing machine and talk about the defects present on the disks.
If the geometry of the disk or disks is broken, you will prompt where it is possible to correct this defect. This operation is performed on a special machine by hot or cold rolling. These machines are not on each tire, so better to find out the nearest shop where you can repair the disks, in case of detection of small defects in the metal or violation of the geometry, so as not to waste time on several trips to different locations. Correction of violations of the geometry of the disc is from 600 rubles per disk.
Remember that purchasing used alloy wheels from an unknown private individual will require their validation, possible monetary costs and your time.
Generally purchasing used alloy wheels has its pros and cons. The downside is that purchasing from a private entity b/a alloy wheels, you'll need to check them, and then possible monetary costs and time. Well if the seller sells officially proven/used drives and gives a guarantee on them. Advantages in buying cast b/u drive too. The fact that during casting the discs can acquire internal defects such as cracks and stresses in the crystal lattice of the metal. But if the disks have served at least one season and the defects are not proved, it indicates that the drives have no manufacturing defects and is thinking about purchasing.
Advice 2: How to choose alloy wheels b/a
Alloy wheels are expensive. Therefore, some car owners for a variety of reasons (e.g., saving money, etc.) considering purchasing already used "casting". So you do not regret about the choice made, you should consider some important points.
You will need
- newspaper ads;
- - computer with Internet access.
First of all, look at the data about the appropriate amount of alloy wheels for your car. Usually this information is listed in the user manual of the vehicle on the sticker in the glove box or the inside of the hatch of the fuel tank. Then decide where you will buy the desired product. There are lots of different options: auto, car repair, an ad in the newspaper or online, from friends, acquaintances, etc. Weigh all the "pros" and "cons" of different ways of acquisition.
Note that it is not enough to only choose the design and the desired size, it is necessary to pay attention to more important parameters. For example, the landing size of the fastener disk on the hub (the center hole diameter, number of holes for the tapered bolts, the distance between them, etc.), as well as the displacement of the surface of the disk adjacent to the hub (wheel offsets). Although in the last parameter permitted deviation of a few millimeters, but this can lead to undesirable consequences: the reduction of emission creates an additional load on the suspension and hub bearings and increase may damage the brake unit.
Carefully inspect the selected disks. Because they may have defects that will adversely affect driving safety and driving characteristics. Therefore, the alloy wheels must not have visible damage. Besides, it is easy to hit him with an iron object. If the sound is sonorous – invisible microcracks are absent. Damaged - publish a deaf sound. On the surface of alloy wheels allowable scratches that do not affect performance properties and should be removed by grinding.
Contact the nearest garage or service station and check the General condition of the selected instances on a balancing machine. Thus, you will be able to check the deviation from parallelism, eccentricity gadfly and boarding the plane, etc., Ask the master to evaluate metal fatigue, as the number of kilometers traveled will affect the status of the disk in the future.
If you buy the disks under the existing tyres – measure the width of the rim. Remember that if you use too narrow or wide disks violated the driving performance of tires.
