Smilin_ Ed, I doubt that there are less bearings in the T 1000 than in any previous 3 shaft engine.
If you want to check, this link gives access to all the big engines
Large aircraft engines - Rolls-Royce
lomopaseo, how sure can one be that a simple switch to a stronger bearing - or several - will solve the obviously existing problem ??
Do you think itīs just bearing ??
