Loctite or not ??

[Lucky_Lou]

Since i fitted my high bars and invested in the appropriate mirrors i found the L/H side keeps moving.The thread is a bit short so i recessed the hole under the clutch lever where it fits. I got a nyloc nut on it but no room for a washer so im thinking of Loctite as the solution an thoughts ??

Hello, fellow traveler! Used Loctite on one of the 81's mirrors as it just would not stay put without it. Red was my weapon of choice.

Loctite should do the trick, but I would recommend the blue.  The red is intended for permanent affixing, the blue is supposed to be used on stuff that may be removed.  I used the blue on wheel studs on my car, the studs broke before the loctite let loose.  Even with the blue, the studs could not be extracted (broke two extractors) and I ended up having to drill them out.

If you want to remove a stud or nut that has Locktite Red on it, heat up the fitting.  I never had a problem removing a fitting with a little heat.

I'm thinking there was more to the wheel stud issue than just the Loctite. And 2x on a little warmth from a heat gun. That works, for sure.   Monte

Is Loctite really a solution when using a nyloc nut?  I thought that Loctite didn't work with plastics.  I'm sure it would be fine with a regular nut.

Nyloks have metal threads just as do "regular" nuts. The primary difference is the nylon insert added as an anti-vibration/thread loosening assist. Plenty of metal threads available to utilize LocTite. It is a sorta "pants and suspenders" solution to a concern.

Just a view point from  aviation applications, if you don't have one complete thread past the nut, it's not a correct installation .

If at least one thread isn't showing past the plastic insert in the nut, use Loctite, as the self lock feature of then nut isn't performing it's intended job .

As the nut is barly on the thread seatet on a drilled recess what would happen if i put a nyloc nut back to front ie lock bit first??

You may well end up with mostly plastic 'threads' doing most of the securing .

You could strip the few threads that are holding and end up ruining the mirror thread as well.
It sounds like you need the loctite to stop the mirror turning more than to 'keep' the nut loosening?

[bruce_launceston]

Any chance you could make the thread longer by carefully cutting/grinding the mirror shaft with a dremel or similar tool?
You would need to be very carefull not to overcut and weaken it.
A mini pipe cutter would get you started square, they are pretty cheap.

The problem with that is the mirror "bar" is a larger diameter than the threads 10mm vs 8 mm thread thanks anyway

Have you tried recessing the mount hole on top of the perch?

Did you compare the mirror to your old left-hand mirror, to see if the working stem is of equal length?
If not, I would take the mirror back and ask for an exchange.
