Thrust Bearing Questions - Cryogenics & Graphite Treatments?

[turbotemper]

My question is has anyone used cryogenics to treat a thrust bearing? I read the thread about the graphite treatment and thought shit together that might be a strong piece once treated.

I havent tried it but here is my question. How hard should it be? If its too hard dont you risk prematurely scarring the crank rather than the softer thrust bearing just wearing?

Coating the bearing, or making it harder is not the answer. A load surface should never contact the bearing anyway. Some how the oil film in between the crank and thrust surface needs to be maintained.

I just posted this last night, actually. http://www.dsmtuners.com/forums/cyl...earing-modification-crankwalk-prevention.html

This will assist in keeping the thin oil film between the rear thrust face and the crank's thrust surface maintained. Helping overcome pre-mature thrust bearing failure and bearing wiping (of course, those two go hand in hand). Read through the thread I think you guys will like it.

I also posted pics of my own thrust bearing I did this to. Also, I had my main bearings graphite coated.
