I've been tuning the TCU to fix up the transfer clutch, it's going pretty good. I thought about break-in but it's my understanding that the factory breaks them in. When I bought the new ones from Subaru I could see they were worn already, and they were all in a matched set (already assembled) and covered in fluid. They may need to break in a bit more, we'll see.
I had to use the old style high clutch drum to use the special Kolene 1.52mm steels. With the newer drum I could not get 6 frictions, the tooth pattern is different. The old drum also required the weaker reverse frictions, unfortunately. I think there is some drum that's in-between that takes the Kolene 1.52mm steels and the newer reverse frictions, but I couldn't find one.
I was able to use the smaller bearing thrust plate and newer hub, so that's an improvement.
