Bearings

Postby 1500J » Sat Feb 02, 2019 1:15 am

What are your opinions with these main bearing races.  Working on a 1500 that sat a long time and the needles left marks on them.  I believe it will polish out fine and they cannot be felt.  

I think the oil sludge that dried out in the bearings is what makes the marks.  Not rust by any means.

Ooof! Not sure I like the looks of that. I am skeptical about using a bearing like that, even it it feels OK. I will look and see if I have a good used one for you.

Conrad, if its dried grease solvent should clean up the marks.  If its surface pitting it wont.

George, Ive got a bunch of used ones.   Just seeing what you guys think about what Im looking at.

Its undetectable by finger nail.     It looks like it's pitted.  But it's just stained, and solvent did not remove it.

I need to get a magnifying glass out and look closer.   And take a razor blade and run over it and see if I can feel it with that.


thanks
Conrad

If you have any better ones, use them. Looks like spalling to me, and I would not feel comfortable with you using that bearing if it is. Not worth taking the chance.

I agree if the stain does not come off easy after soaking for a few days, I will use other ones.
