Unless you were changing a blade or a worn PCL rod end there are very few reasons to remove or adjust the PCL's on a 135.
The rod ends are keyed to remain 90 degrees to each other.
Yes on 2 of the links you have to remove the swashplate drive links to remove the lower PCL bolts.
Luckily there are 2. Loss of one would not make a lot of difference. They can also be installed backwards!
Sounds as though the issue is not with the aircraft.
There has been nothing come out from ECD recently in the way of Safety Notices although no doubt there will along with the other gems like - please take off using both engines, please leave master on until engine stops to avoid incinerating engine, please understand how to use manual FADEC control, please understand TRAINING MODE, do not arm floats above 80 knots, don't fiddle with jettisonable door levers, be careful when dealing with flight controls having LH threads, don't fiddle with the FIRE (fuel valve) switches and guards, don't take off with the cyclic centring lock engaged (although by now you shouldn't be able to), etc etc.
I am sure that the poor guys at ECD really wonder about what customers do to their aircraft. Sometimes they even have trouble understanding what their own people do to them as well!
