bearfoil
Sorry mistake in my post. Itīs of course not the nr. 2 roller bearing but the nr.2 ball bearing. The one that takes care of correct rotation of the IP shaft spline, catches the foreward forces of IPC and HPC. I concluded the involvement of that part of the engine in the entire problem because of the limitation to only 75 cycles at 540 psi at p30. Where else does all the extra pressure, heat and forces in that environment go to ???
