Motor Rotor Wear

[Dieselman 63]

The Selecta grinder is in bits again. The bearings sounded worn so I took them off, though they feel fine I'll see how much replacements are - obviously been replaced before as they're SKF so shouldn't be too hard to find new ones. I decided to have a look at the rotor and I must say I'm a bit unsure about the wear pattern on it.

The stator has light surface rust, as can be expected, but the rotor has more involved rust around the edge and also has worn through to copper pins on one side which makes me think it may not have been running true at some point in its life? What do you think I should do?

If it worked just replace the bearings and reassemble.

It's been making some funny sounds since I bought it. My little Wolf is really quiet, almost silent in comparison. I will try bearings first then see if it's still up to it's tricks...

Mic the shafts and check for concentricity of them to ensure the assembly is running true.
