About the GB failures: some years ago I got some TR GB main Brgs.
directly from the TR parts Dept. and they were looser than the Brgs.
that I wanted to replace! I went to the facility and checked all the brgs.
that they had. All were too loose. The high quality ball brgs. have three
burnish marks on one face, the worst ones have none. The GT6/spit
ones are now the same. Check how much your GB's 1st & 3rd motion
shafts move about, and then wonder how the GB has lasted at all!
There is a fix for this.
