i just thought about it : shouldn't the backlash of the pinion and the crown gear give me an indication of how "deep" the 6207 Is?

That will keep me busy for the weekend .

or any one that came across this thing before?

Hi
I just finished restoring the rear wheel hub with new bearings gaskets etc.
When I rotate the shaft pinion by hand I turns of course but It needs some effort to do so. Like after few turns my fingers start to hurt.
Is it normal or should things rotate fast and easy even by hand?
Thanks

Hi

I just got a used Voltage Regulator and a resistor . The seller listed them as "for parts/not working" cause he had no way to test it.
Any way to tell ?

Thanks

What's the way to tell?

Thanks

found it one eBay and waiting for a quote from the seller
Anyhow, do you think that this is the part that was to blame for the rattle? And if there's maybe something else that could make the rattle?
Thanks

I'm restoring my R51/3 and i recall before taking it apart (I rode it for few months) , I noticed that for 3 seconds just when I was about to fully release the clutch , the back wheel and the whole back axle was shaking and rattling . After 3 seconds it was ok but it happened every time I started mo...

i think I figured what's the 77mm for , distance between the inner side of the pinion ball baring to the center of the disc gear . I just inserted the pinion all the way inside and measured it and it's exactly 77mm.

That's what I wanted to know , I appreciate it a lot.

What about the 77mm for the "ideal adjustment value in housing" ?
What's that?
