1, see whether the trademark logo is complete

The quality of the outer packing of genuine automobile fittings is good. The writing on the box is legible. The colour is bright. Packing box。 Bag. Product name should be marked. Specification model. Number。 Registered trademark。 Name of factory, address and telephone number, etc.. Some manufacturers also play their own tags on accessories. Some important parts, such as generators. Distributor. Injection pump, etc.. An instruction manual is also available. Certificate and surveyor's chapter. To guide the user's proper use and maintenance. Should be carefully identified when shopping. In case we buy fake and shoddy products.

2, see if the geometry is deformed or not

Some automobile parts are made. Transportation. Improper storage. Liable to deformation. Inspection time. The shaft can be rolled along the glass plate. See parts and glass plate joints have no leakage to determine whether the purchase of bending, clutch plate or steel friction. Steel sheet can be used. The friction plate is held in front of the eye to see if it is warping. The face of oil seal with frame should be round. It can be fitted with flat glass, without bending, without skeleton, and the outer edge of oil seal should be straight. Deform with a hand. After letting go, you should be able to restore the original condition. When buying all kinds of gaskets. Should also pay attention to check geometry size and shape.

3, see whether the joint site is smooth

Automobile spare parts are carrying. In storage. Due to vibration. Bump. Burrs often occur at the joints. Indentation. Breakage or crack. Affect the use of parts. Should pay attention to inspection when shopping.

4, see if the parts are rusted or not

Qualified parts, surfaces. Both have certain precision and polished finish. The more important parts are. The higher the accuracy. Packaging, rust prevention and corrosion more stringent. Should pay attention to inspection when shopping. If corrosion is found in the part. Mildew spots or rubber pieces. Lose elasticity. Or the surface of the journal is obvious. Shall be exchanged.

5, to see whether the protective surface is intact

Most parts are coated with protective coatings when they leave the factory. Such as piston pin. The Bush is protected by paraffin and the piston ring. The surface of the cylinder liner is coated with antirust oil and wrapped with wrapping paper. After the piston is soaked with antirust oil, it is wrapped in a plastic bag. When buying, if found the seal is broken. Lost wrapping paper. The rust oil or paraffin wax loss should be replaced.

6, see if the adhesive parts are loose or not

An assembly made up of two or more parts of two or more parts. The parts are pressed by pressing. Adhesively bonded or welded. Looseness is not allowed between them. If the oil pump plunger and the adjusting arm are assembled by pressing, the clutch follower and the steel plate are riveted together. The friction plate and the steel plate are riveted or glued, and the filter core, the filter core and the filter paper are glued together, and the thread of the electrical equipment is welded. When shopping, if found to be loose. Shall be exchanged.

7, see if the rotating parts are flexible

When selecting the rotating parts such as the oil pump, etc.. Turn the pump shaft by hand. Should feel flexible, no lag, when buying rolling bearings. Support the inner ring of the bearing at one hand. The other hand circles the outer ring. The outer ring shall be able to rotate freely and rapidly. Then stop gradually. If the rotating parts do not work smoothly. Indicating internal corrosion or deformation. Do not buy.

8, to see if the assembly parts are missing or not

Regular assembly parts must be complete and sound. To ensure the smooth assembly and normal operation. The missing parts of some assembly parts are missing. The assembly parts will not work or even be scrapped.

9, see if the assembly mark is clear

In order to ensure the assembly relationship, meet the technical requirements. An assembly mark is marked on the surface of some parts (such as timing gears). Illegible without marking or marking. Will bring great difficulties to the assembly. Even wrong.

10, see if the surface is worn or not

If the parts have worn marks on the mating surface. Or paint accessories, after the surface painting, found old paint. Most of them are made of waste parts. You can exchange it at this time.
