Firstly, genuine bucket teeth castings have markings and grades; counterfeits either have no markings or have rough markings.

Secondly, genuine bucket teeth have thicker sidewalls, with the seat groove and heel fitting tightly together; counterfeit bucket teeth have thinner walls, and the gap between the seat groove and the front of the tooth is usually too large.

Thirdly, the weight of genuine bucket teeth is 6kg (taking 220-5 as an example), while counterfeit teeth generally weigh around 4kg. Counterfeit bucket teeth lack strength, are prone to wear and tear, and can easily break. There are casting errors in the mating part with the tooth root, which can cause installation difficulties or the teeth to fall out due to excessive clearance during excavation. Moreover, using counterfeit bucket teeth increases the driver's labor intensity and affects work efficiency.

At the end, the dangers of using counterfeit fuel injectors are introduced. Poor processing accuracy of counterfeit injectors can cause poor atomization, oil leakage, oil sticking, and other phenomena, resulting in black smoke emissions from the engine. This accelerates the early wear of engine components and causes huge losses.
