First of all, pure bucket tooth casting has a mark and grade;Counterfeit or unmarked or marked is crude.

Second, the side wall of pure bucket teeth is thicker, seat slot and heel fit closely;Counterfeit wall is relatively thin, seat slot and tooth front clearance is generally too large.

Third, the weight of pure bucket teeth is 6kg (take 220-5 as an example), denture is generally about 4kg.Counterfeit bucket tooth strength is not enough, wear and tear, easy to break.Error exists in the casting of the meshing part with the tooth root, because the clearance is too large, it is easy to cause installation difficulties or bucket teeth fall off.Moreover, the use of fake bucket teeth will increase the driver's labor intensity, affect the efficiency of work.

Finally, the harmfulness of using fake nozzle is introduced.False nozzle processing accuracy, will cause poor atomization, oil, sticky oil and other phenomena, resulting in black smoke engine.Accelerated the early wear and tear of engine parts, resulting in great loss.
