Re: [DIYGasTurbines] Need help....vt50 rebuild

Hi Grant,


I know I don't know a lot about turbo's yet but what comes to mind is, you might
not get it back off. Also cast AL thread don't take much to strip out the
threads.


Is it supposed to be that snug?


Nick

Okay, no worries. I got it back on. It wasn't a threaded AL part. It was the diffusor plate. It slips onto the centerhousing and there is an o-ring to seal the...

I want to say that if you need the turbine wheel and going to rebuild your VT50, you are waaaay better off buying the nearly-new VT50 from Bill H. That is one...
