[1960 - R50] Does Someone have problems with Shaft and Flange?
I bought an 1960-R50 ( VIN 563502 ) about 3yrs ago.
The engine needed some repairs,
so, I contact Mark Huggett, and bought new pistons ( R50/2 ),
valves and everything to make the engine brand new again.
I'm not a mechanic, so I leave the bike on a harley mechanic here in Brazil.
( Note: Unfortunately, I don't know any BMW specialist back here )
So everything went fine
but, on my second ride,
I note that when I accelerate the bike,
seems the clutch was "slipping". and the bike loses the "traction"
And, when I send back to mechanic we noted the problem was not on the clutch, but on the Shaft and the flange. ( see the pics )
And now, I don't know what to do,
because if I change the Shaft and Flange
it can happen again.
Does anyone have some problem like that?
Thank you in advance for any help.
my best.
Rodrigo

Rodrigo - Welcome to the
Welcome to the forum! Sorry for your troubles. As I understand it, that is a tapered shaft and the flange has a matching taper. If these tapers don't match and also if they are not absolutely clean and dry upon installation, then there can be a separation. It's very important to have them clean and that the right torque is applied upon installation.

just maybe
These trial are sent to test us and make us stronger - which is another way of saying they are a real pain.
Hope it goes well for you.

I am going to undertake the exact same job myself on my R60 within a few weeks. Mine has the 1:5 taper and a broken key.
I know just what you are

Thank you so much
I was wondering,
They have 2 types of shaft, 1:5 taped and a keyway,
and other 1:6 tapper and no keyway - I think mine is this model, dont have a keyway.
So,
Do you know if
the BMW engeniers changed the shaft with no keyway
for the keyway model on the new motorcycles, because they spot that problem?
If they did that,
Can I change my shaft for a keyway model?
Maybe, this woud be an improvement on my motorcycle.
Or it's better keep the original?
Thank you again
My Best
Rodrigo
