Last night I took my turbo apart to rebuild it as a precautionary measure before putting it on my new engine. Since a lot of metal went through it when I spun a rod bearing.
Glad I did, I found some stuff embedded in the turbo bearings. It appears that it also scratched the shaft. Most are very minor, but a few spots I can catch a fingernail in. Are turbo shafts and bearings like engine bearings in that the shafts can be machined and the bearing available oversize? Or is it safe to chuck it in a lathe and polish the journals with some fine paper (1000 grit +) and crocus cloth to remove any burrs? Can I send just the shaft out to be machined and buy the right size bearings?
