The high frequency noise of Turbo V 81-M (Model 969-8903)

If the turbo is squealing continuously when at full speed and during ramp-up, it is an indication of a bearing problem.

Thanks. If it's the bearing problem, will the pump works at higher current and becomes warmer? It's only 31 degrees.

It may run OK, but the noise won't go away because the rotor bearings are bad and can only get worse.
