So, I'm getting seriously into my turbo project and I need to clean/recondition my Rajay turbo. It's supposedly never been run (according to the guy I got it from) and I'd buy that given the flawless condition of the rotor on the exhaust side. The bearings don't have any slop and the blades are perfect and free of carbon. However, it's been setting around for years and it doesn't spin as freely as I think it should. It spins easily, but it won't continue spinning (you can flip it once and let it spin a while). I figure it's just dirty inside, maybe some old gunked oil. How do I tear it apart? Can I still get the gaskets for it? Anyone got a diagram or instruction manual or anything? I believe (from memory) it's a 377B25 or something like that. It's the one that came with the CB750 ATP kit. I don't suppose there's a more modern turbo that shares the same flanges that I could get instead?
