I have an eccentric shaft out of a 12a. It's in really good condition, but on the end of the shaft (Pulley end) there is about 4 scratches, the worst one is about a half an inch long and maybe a cm deep, give or take. This might be a stupid question but is it still usuable and is there a way to fill them in? Thanks.

 

Does the pulley cover it , if so keep going , does a bearing run on it , if so not so good

 

a CENTIMETER deep??? (about 3/8")

I wouldn't use it if it's THAT deep....

 

Sorry, I mean't a millimeter, its really not that deep.
