G'Day All. Great forum, with lots of good advice.

Bit of a problem with the left-hand fork on my 76 Bonnie leaking fluid in the area of the top nut, under the tacho mounting plate. Not just a few drops - about 1-2cc over a 10 mile trip. Have tried gasfitters tape around the thread of the top nut where it screws into the stanchion - no difference.

The Haynes manual suggests caulking compound, but I don't know if this will seal the nut in the stanchion forever, never to be removed.

Any advice??

Thanks

Peter

PTFE tape should have done the job.. but failing that, if you can get your hands on some blue Hylomar down there in Oz, that should fix it.

Hylomar is non-hardening. It seals pretty much anything and it can be removed with thinners. It was originally developed by Rolls Royce as a gasket goo and it works well.

I've had good luck with the Yamaha Bond products (I know, I know, Japanese etc.). Just spread a bit on the bottom of the sealing surface and let it set up a bit, then re-install the item. It comes in 2 grades, hardening and non-hardening; I'd suggest the non-hardening. Oh, by the way, check the fork leg, etc, for any cracks and you won't go through what I did when my old BMW began to leak fork oil and I thought it was coming from the cap. That one could have gotten nasty.

Good Luck with it: Jim
