How to choose the right auto parts
1, to see whether complete trademark
Good quality authentic packaging auto parts. On the box legible. Overprint bright packaging cartridge on bags should be labeled with the product name. Specifications Model The number of registered trademarks. Make the site and phone number, etc. Some Parts manufacturers are still making their own mark on some important parts such as generators. distributor injection pump, etc. also has instructions for use. certificate and inspectors Chapter to guide users to the proper use and maintenance. purchase should be carefully considered clear. prevent buy fake and shoddy products.
2, to see whether the deformation geometry
Some auto parts due to manufacturing Transportation. Stored incorrectly. Easy to produce deformation check. You can scroll around the glass along the shaft parts. Look at the parts and glass bonded to determine whether the presence or absence of light leakage bent, buy clutch from the movable plate steel or friction moment. You can steel friction plates held in front observe whether warp in the purchase seal. Seal end face with a skeleton should positively circular can be mixed with plate glass bonded without flexing No oil seal outer edge should be correct. deformed by hand after the restitution should be able to let go. In the purchase of various types of liners also should be careful to check the geometry and shape.
3, to see whether the formation of binding sites
Automotive parts during handling. Storage. Because vibration bump. Often produce glitches. Indentation in the binding site. Breakage or crack use affect parts. Look out checks.
4, to see whether the parts of the surface rust
Qualified Parts surface has some precision there burnished finish. The more important parts. The higher the accuracy. The more stringent packaging rust and corrosion. Purchase should be careful to check if there is rust spots found in parts. moldy spots or cracked rubber parts. loss of elasticity. or journal surface lines have significant tools. should be replaced.
5, see protective surface layer is intact
Most parts in the factory are coated with a protective layer, such as the piston pin. Bush with paraffin protection, piston rings. Cylinder coated with anti-rust oil and wrapped with wrapping paper, valve after the piston and other anti-rust oil dip with a plastic bag package. if found damaged gland purchase. wrapper lost. rust oil or paraffin drain. should be returned.
6, look for loose parts glued
By two or more parts are combined into accessories. Between the parts are fitted by press. Glued or welded. There loosening between them is not allowed, such as the pump plunger and the adjustable arm is fitted by press combination, Clutch Yi and steel is riveted combination of friction plate and steel is riveted or glued, paper and paper filter element skeleton is made of glued, thread electrical equipment is welded. If found to have loose purchase. it should be replaced.
7, see the rotating parts are flexible
When you purchase machine pumps and other rotating parts assembly. Manually rotate the pump shaft should feel flexible cable wiring, the purchase of rolling bearings. Handedly support the bearing inner ring. Another hand to spin the outer ring outer ring should be able to freely rotate quickly. Then gradually stop. If the rotating member rotation is not working. Description Internal corrosion or deformation. Do not buy.
8, see whether the missing parts assembly components
Regular assembly member must complete and intact. To ensure a smooth assembly and running. Individual small parts on some of the assembly members if leakage loaded. Will. Assembly parts can not work or even scrapped.
9, see the assembly mark is clear.
To ensure the assembly relationship fittings meet the technical requirements. In some parts (such as the timing gear) surface engraved with the assembly mark. If there is no sign or mark fuzzy illegible assembly will bring great difficulties even installed wrong.
10, see the mating surfaces for wear
If the mating surfaces of the parts of wear marks. Or poke the surface of the paint after painting accessories found the old paint. Is mostly discarded pieces of camouflage this time may require returned.
11, to see whether the target surface hardness
Each fitting has a surface hardness requirement specified in determining the purchase and the merchant provider after duly Available hacksaw stubble plan to try when planning skid scratch-free. Description High hardness, scratch a little after shallow marks high hardness, after the draw has obvious traces. Description low hardness (test draw attention not to damage the Face).
