Morning all,

I hope everyone is enjoying the superb weather.

I am in the final stages of completing my Raleigh Rapide and have a small problem. The right hand gear shifter keeps working loose. It took me while to remember that i had changed the levers 25 years ago because of this but now i need a solution. I can tighten it fairly well with a screwdriver but after a while it works loose - i retighten and it loosens again.

Al-onestare suggested Locktite - will that completely stick the nut? I am reluctant to use this if it make interfer with the actual operation of the lever.

If the problem is caused my worn fittings, i should have some spares to sort it out.

Link to the build -

All ideas welcome,

Richard

p.s. I am sure you will all be glad to hear that this is the last obstacle before it is actually finished!!!

Are they friction shifters or indexed? If friction then check that all the bits are there, if they are then it's usualy a matter of tightening them by hand while riding as necessary as they had a habit of doing that...... I guess that's why Campag / simplex etc had the ability to tighten them by hand.

We used to swap screwdriver only shifters for hand tightened ones for that reason......

Thanks Shaun,

They are friction - Campag levers and i am pretty sure all the bits are present. So i should look for hand tightenable screws?

That's what I would do.............trying to lock them in place with cyanoacrylate will work but doesn't take much to escape and coat the shifters. I wonder if anybody is selling something broken on the bay?

Are yours GS campag?

Shaun,

I have no idea, the mechs are 980 i think. I might have some screws in one of my many boxes of bits.

You got the washers all correctly fitted in ?
Do you look carefully at the levers as to why they unscrew?

I bet these would fit but be quick !!

Blue loctite shouldn't cause an issue (it's designed to be used in placs where the parts need to come apart semi-regularly).

I'd agree with the others on here who've suggested hand-tightening types though (seem to recall my downtube shifers BITD had metal D-rings on them just for that purpose).

Thanks,

And thanks Ian but i was too slow. I think i might have those in a box somewhere.

I am pretty sure the washers etc are in the right place but can they wear? Would it worth trying another set?

I might have another solution -

but it might be unlikely!
