forks

[Tone]

Hi all, I have finally sealed the drainplug on the bottom of my forks, but have found out it's leaking from somewhere else at  the bottom so I've taken the leg off and split it, poured some petrol in but I can't see it leaking anywhere! any ideas.

Common thing is for them to leak from the seal holders - oil seeps past the threads then runs down the slider and drips of the bottom, maybe evn off the drain plug.
Run a clean tissue down the back of the slider to make sure this is not where it's coming from

I always use loctite 243 thread sealer [available from Halfords] on the seal holder/leg threads and have never had a leak. All you need to do is clean and dry any oil from the threads, apply some 243 around the threads and tighten it up. I always leave for 24 hours before filling with oil.

It wont be leaking from the drain plug unless its been butchered, but leaks from the seal holders can look like its leaking from the drain plug.

Thanks guys, I'll give it a go, cheers.

Hi
Thats where mine leaked too,

On another bike i noticed there was some thread of some sort wound round the threads of the fork slider to seal holder.

I used PTFE plumbing tape (that thin white tape for plumbing compression fittings) it works a treat.

That thread was fitted in the factory. The relevant Service sheet refers to number 2 twine, and in the old days we used hemp for things like that.

Andy I think they smoke hemp these days

I just found the twine on my chromed legs, so someone must have either replaced it, as I doubt they came from the factory fully chromed?
