I also had to replace the starter drive adapter on my IO-550 (non turbo) 
after about 50 hours.  In my installation we only had to loosen the bolts 
holding the engine, not pull the engine.

I have heard from a number of people about starter drive adapter problems - 
I think it is fairly common.  In talking with Allen Barrett of Barrett 
Precision Engines about this problem, he said that not all starters are 
equal with respect to causing this problem.

I would be interested in hearing from him what the data suggest about which 
are the best and worst starters with respect to the starter drive adapter.
