The counterfeit timing chain of Ruian Хаю Автозапчасти Co. is an option of the industrial chain 06B-1 of the ISO 606 standard and is not suitable for car engine. It`s use as a timing chain may lead to chain break directly in the car engine causing the damage of the motor and valves.
The results of the testing of the counterfeit timing chain proved that the chain does not comply with the requirements for the automotive 9,525 mm pitch simplex timing chain due to breaking load, geometrical features and the steel hardening quality of chain parts. The chain did not pass the test for wear resistance regarding the elongation aspect, which is twice higher than the norm.
