York AC compressor bearings

[flyboy2610]

I seem to recall reading something about compressor bearings in a remanufactured compressor being destroyed by R134a.
I could be wrong about that, but IIRC the gist of it was that the bearing material wasn't compatible with the PAG oil used in an R134a system.
I should think, though, that reman units would have compatible bearings by this time.
Could someone who knows et me straight on this?
I have a remanufactured York compressor I plan to use, but don't want it to self destruct its bearings.
Help?

Yes,

It should be OK.

Back when 134A was first introduced and we all got our licenses it was a problem.
The problem lay in the "mixability" of the existing R-12 mineral oil with the newer 134A synthetic oils, (pag, ester, etc.).
We were taught that retrofit's needed 90% of the mineral oil removed when going to 134A to prevent this.
If it's never had 12 in it, you're good to go.

Great!
Thanks, Jeff, for the info!
It's a rebuilt unit, still in the box, so I guess I won't worry about it.
