Trying to assemble a hybrid turbo, but
I finally got the whole broken CHRA thing sorted out. Turns out, this turbo is a TO4B hybrid (possibly bnr or something). The chra was busted, and it fell apart when I tried to index the turbine side. Then, turns out it had a 360° bearing instead of a 270° thrust bearing. So after getting the NEW CHRA machined out to accept THAT, I've been trying to put it back together.
I just can't get the damn shaft all the way in. That doesn't sound right.
Anyone ever have this problem? It's the seal ring on the turbine side. I just can't figure out how to get it all the way in the center housing. Anyone got any good tips?

I have rebuilt a couple stock and bnr turbos. I had the same problem at first. That ring that they supply in the rebuild kits to me is too big. I used the old ring, tap on it with a rubber mallet and it goes in. Never had any problems since then. Put the turbine end on some wood and just use push down as hard as you can on the chra.
Maybe you tried that already though.

If you're talking about the metal piston ring that goes on the turbine side it should fit just like a piston ring in an engine does. Colapse it with your fingers and see if it fits into the bore on the chra. If the ends are pushed together and it won't fit you have the wrong piston ring. It should go in firmly but not forced, there should actually be a small end gap with it in the bore.

Got it finally. I've been... away for a while.
Turns out that there was a bushing inside that will go in backwards. It's all part of that 360 bearing thing. Once it came apart it was pretty much apparent that I was retarded. It went together so easily once it was properly assembled.
