Laydown gearbox kickstart shaft washer

Hello Anna. Thanks for your reply on this and my earlier request for a source of spares on another message. I did manage to get all I needed (not much required it turned out) from RGM. The full bearing set was bought from Simply Bearings at a pretty good price with fast and cheap delivery.

Just to say; I know where the cork seal is fitted, thank you,but I wanted to know where I could BUY one. I have ordered some O rings to experiment with fitting some to the kickstart shaft without doing any modification. I'll let you know if this is successful or not.

I wouldSTILL like to buya kickstartshaft oil seal or washer though. It's strange that with all the members in this NOC that apparantly NO-ONE knows. very odd! You don't have one do you Anna?

Thanks very your reply John. I was thinking of doing the same with some cork sheet. I think you have to get the old original anduntreated cork, the resason being that corks expands when in oil or petrol which is how petrol taps use it. My old cork washer (split) was around 2" squashed hard and dried out. The ability for the cork to swell exerts the sealing pressure. I think yourmodis best and should work excellently. Unfortunately I don't have a lathe. I tried a few o rings in the standard groove. the ideal thickness is I would say, 1.2mm. I have managed to get 1mm in the standard groovesbut they are just a fraction too loose in the bore. and 1.5 is too big. By the way,I don't have any internal drilling as you mention so both mygrooves can be used. I'll see how it goes (probably take another year to finish the bike) It's an easy part to remove, not loosing much oil either.

Hi Anna, thanks for kind offer to look for the cork seal. Would appreciate it if you do find one, I'd like to fit it just to see how well or not it does.

ATB to you both.

CORRECTION: OLD CORK WASHER WAS SQUASHED TO ABOUT 2MM (NOT 2")

LP, the drilling to which I refer is the internal cavity in the K/S shaft which provides a home for the layshaft bush.This depth can be variable and may not have been toleranced on the drawings, but left to the judgement of the machine setter.I cant remember the relevant dimensions, but I remember thinking that it might be a trap for beginners. We have all parted a component in two with a groove or a bore, but its funny only when it belongs to someone else.Regards John.

Thanks John I have the picture now. I was imagining the drilling you mentioned was a hole that pierced through the kickstart bush (tube) . I can see what you mean now.
