Yeah that was what I was thinking. It is deffinately some sort of grinder that was used to remove the material.
There are also some other marks where there was some material, it looks like little half moon shapes on the outside edge of the back side of the comp. wheel. Im thinking those are balancing marks as well.
Is the compressor wheel balanced by itself when you do a balance job?
Can you tell me the steps you take when you balance the shaft/wheels?
