This paper describes the change in the vibration of the teeth in the process occurring the initial surface failures of gear teeth. First, the torsional vibration characteristics are analysed of a gear pair with several profile errors and frictions between the teeth. The maximum of the tooth root stress is found to be desirable for observing the vibration characteristics connecting with the tooth failure. Second, the pitting test is carried out to find the typical change in the maximum of the tooth root stress during the test. The pattern of the typical change is as follows: The maximum of the tooth root stress increases gradually with the number of load cycle, then reaches to the peak because of its decrease due to the pitting of the tooth.
