it looks like you are missing some parts on that bad side maybe a spacer or sumthin between the head and blade grip what kind of heli is it???? but my guess is that you are missing some very important spacing parts in that side of the blade grip assembly... maybe take it apart and keep the part from each side seperate and in the order that they come apart and if you have the manual for the heli look at the parts blow up sheet of instruction and double check everything in the picture is laying in the order they are suppose to be... as far as loctide never use anything more then medium or blue loctite and only on the screw that goes into the feathering shaft maybe after you get it apart and take a photo of all the parts and post it up we can help you out as to wether or not anything is missing or out of order...

Yeah...I would definitely NOT attempt to fly it this way. What you need to do is take it all apart and follow the illustration that Tony provided, above. Double check that you have all the correct spacers/washers and bearings in place. You are definitely missing something.

Well if you havent touched it or took it apart, then maybe the screw are coming undone...Yes! you can use loctite.

Yup, just follow the video below so you don't get any in the thrust bearing, or sealed bearings.

This may be a dumb question but is the dampener missing? That is a lot of slop seems to me you are missing something major not just a washer.

Check the length of your feather shaft. I mean if all parts are there and you even added two washers. the only thing i can think off is the shaft or head block is wrong size.<-----lol.. is that what you call it. JK i ment rotor head

Dampner would be in the hub and not really contribute to that kind of slop. Seems more like a radial bearing is missing from inside the grip. Something letting the whole blade grip slide out too far. More than washers. That amount of movement looks more like a missing radial bearing. And it the missing part may be on the other "good" side. The dampers will be pretty tight on the feathering shaft so if you have that side drawn down tight and it is missing a piece or two, that can make the side with the apparent play look bad when in fact it is the other blade grip with the issue.
I'd suggest taking the blade grips off both sides, take the pieces out carefully (small pieces love to fall out and you don't even notice them or have a hard time finding them) and lay them out in the order and position that you remove them and take a pic so we can see what's there and what's not.
Should be something like:
screw, small washer, thrust bearing (three pieces), radial bearing, blade grip, spacer, radial bearing, washer, damper and then the same pieces in the opposite order for the other grip, in the middle the feathering shaft. You may only be able to get one of the retaining screws out. That's fine, do not try to grip the feathering shaft with pliers or something in order to get the other screw out. Just leave it in and note it. Don't want to mar the feathering shaft with plier marks, or worse bend it or deform it.
