Catalytic hood bearing discoloration, please seek help for the reason
The bearing bush is attached with a paint film, a product of oxidation of the lubricating oil.
The lubricating paint film phenomenon, with such a small area, is normal. The main thing is to check the bearing bush for other defects.
Check this tile to see if there is any problem with the backing part of the tile, caused by a large gap. It is caused by uneven contact surface deviation with the shaft. For reference.
The oil temperature is below 40°C. This has never happened before.

There is wear on the bearing bush, but it's not serious. Have you scraped the bush?
Tips from the Design Institute: It's not that the oil temperature is too high. Instead, local friction is severe, resulting in excessive local temperatures and traces of lubricating oil deterioration. As long as the bearing RTD does not alarm, it is not a big problem. But since you have already disassembled it, there should be a problem. Let's ask Cinnabar to check the contact surface area between the shaft and the bearing bush.
