Jeff's 727 rebuild thread

Yes. Dont remove those four balls. They are permanently there from manufacture. The window in the tailshaft bushing is to allow atf to lube the slip yoke and bushing. Be sure to index it the same as the existing one. I have put the notches aft before, freeze the bushings and warm the tailshaft before installation. I use some red loctite sparingly on them. Before you reassemble everything make sure your slip yoke fits the new installed bushing nicely.
