As Rotor said...
There's little reason to locktite a bearing in place, MHO
The theory for this is if the bearing goes, you want the bearing to self-destruct before it spins and takes out the shaft or outer race mounting.
This will probably never happen in the grips, maybe once in a million years, but you shoulda checked 'em in May of 2508!!! ;-)
In the tail "flanged bearing" mounts, maybe, but can you get the old bearing out without ruining the side plate??? Can you locktite it without danger of getting the stuff into the races??? What's your time worth??? Food for thought...

Not to mention grip bearings don't see the rotational forces that main shaft bearings do.

... Am i missing something here!!??? The "Click" mentioned on other posts seems to me to be the blade grips moving on the Bearings. If you tighten the grip bolts up, you will clamp the 2 bearings between the head of the bolt and the feathering shaft. This "click" is just the blade grips moving back and forth on this bolt/bearing/shaft assembly, once tightened.
IMHO, reducing/filing the feathering shaft will only cure this "clicking" or movement by reducing the gap between the grips and Yoke... The dampers will then not do anything and the feathering shaft will not be able to tilt.
SO the advice is DEFINATELY locktite/Shoegoo the bearings into the grips... this will stop the movement and clicking... Else let centripetal force keep the grips in place.
Sorry Goldslinger, i just can't see any other reason for the clicking you found :confused:
