Going back to Bob's question in his post #21 about common failures in R975s, another one that I have come across more than once is that the eight small high tensile screws, that bolt the gear onto the rear section of the crank, fail and there is then no drive to anything on the back of the engine. This usually does not result in any seccondary damage, just a dead engine. It is a huge amount of work to replace them but doable by a competent person who reads the TM and can work very carefully.
This failure is easy to check for as nothing on the back of the engine goes round when the engine is turned by the fan. Also of course the starter does not turn the engine either.
