So to make it clear, this is what happen:
The clutch was slipping a little bit and there where marks of oil between the clutch bell housing and gear box.
Took everything apart and the result was the follwoing
- clutch slave cylinder was rebuilt
- gear box input shaft seal was changed as this one was leaking
- the plate with the abrasive material on it (I don't know the exact name for it in english) was replaced. It has a thickness of aprox 6.8mm.
All the other parts are the old ones. The actual push rod on the bike is not exactly like the one in the link. It's the old type push rod with out the felt seal groove.
Now at re assembly, with everything in place and checked 3 times for correctness, the push rod dose not protrude enough for the slave cylinder piston to engage it when 6 screws are tight. The slave cylinder piston reaches the end of it's travel, stopping in the circlip.
If the 6 retaining screws are finger tight everything seems ok, but when they are tight the spring diaphragm is to far.
I'm really out of ideas with this problem and can't find anything on the web or in the original BMW manual.
Thanks for all the input and I'm waiting for any other suggestion that can shed some light on this issue.
