Another Loctite issue?!

6000 miles

Recently both my rear view mirrors were loose in their mountings on the fairing. Opened up the respective panels to tighten the nuts and found that one nut on each mirror had completely fallen off!! Coincidentally, both the nuts were the lower ones.

Not sure if Yamaha ever used spring washers on these. Installed new nuts, but haven't used Loctite on them yet. Should I, or is something more basic wrong here? Haven't seen this coming up on the forum.

Thank you.

Loose mirror mounts right from the dealer came up a few years back. It was in the context of fuzzy mirror images if I remember correctly. One of those things to check. Never heard of both sides with nuts fallen off. Mine were fine until I had a low speed crash. Some blue loctite wouldn't hurt I guess, but "snug enough" works for most.

EDIT: See scabs post:

And read step #3 in this most excellent how-to post by Hal (Kaitsdad) where he references the use of blue loctite to the mirror fasteners because of loose nuts:

Thank you ShinyPartsUp for your detailed response and the links. The 2nd link was my situation, and it was bad to know that some GenII bikes had this issue, but good to know that mine was not a unique situation.

Now to the Loctite.

I strongly suspect this was simply a case of the dealer not tightening the nuts up sufficiently.

The lower nut of the two is not a straight run for a socket. Since putting on the mirrors is a dealer function, perhaps he was in a hurry. So maybe not a coincidence?

Having had to replace one and remove the other of mine

, I found they were both OK. If they are tightened reasonably, I don't think Loctite is necessary.
