Transmission breather bolt on R60?
Transmission breather bolt on R60?
I recall that my past bikes, /5 and /7s, had a bolt by the speedo cable that vented the transmission. I may have this recollection wrong, but thought that it should be the same for my 1960 R60.
That said, I've had some gear oil (yes, sulfur smell) leaks-- indeed puddles-- getting worse recently, which I noticed yesterday during a funeral cortege ride for a local biker (I'd topped up levels the night before based on the handbook, which I realize can be a bit generous). The leak would appear to be failing seals, but I went to check that vent bolt this morning, and it turns out to be solid! No hole at all (see pic).
Like I say, I could be wrong...but I thought the bolt was supposed to look like the other pic attached. There's gear oil actually coming up and dripping under the speedo cable boot. Jeez. What say ye gurus?
While we're on the subject, anyone have a vintage BMW service guy/gal they like in southern England? I used to live in the SF Bay Area and had the likes of Duane et al to offer kind (sometimes sharp advice. Over here I've only come across Anson Restorations, and they're wayyyy up north. Thoughts welcome. Thanks all!

The seals will need replacing anyway, but in the meantime I'm off to Salis to find a holy bolt... Thank you all for the speedy replies and help!

Re: Transmission breather bolt on R60?
A simple solution might be to remove the bolt, find a friend with a drill press or preferably a lathe, and bore a center hole to match a vented bolt.
The hole appears to be 1mm in diameter, (as a 1mm wire just passes through it) then chamfer the end with a larger bit, to match, same as the picture you've provided, and Robert's your father's brother. (or something like that...)
Best-
