inner alternator cover bearing

[mauricejota7604]

Hi all during the assembly of my 1977 1000 build I have found a washer behind the bearing that sits in the inner alternator cover the bearing that would sit against the starter clutch, I cant seem to find any drawings of any such washer in my books and you would think that this bearing must find its own position as that stepped nut would lock against it???
Your opinions would be appreciated. :-* :-* :-*

Muarice,

Is the washer installed against the inner or the outer race?

The stepped nut is supposed to tighten the whole sprag clutch caboodle up on the crank.  Very often this is not the case, allowing a little movement between the individual components, which, as a consequence, wear at the contact points.  To fix this without replacing the whole lot, I machine the sprag body flat and insert a spacer washer to take the place of the material removed.  The nut often also requires a bit of dressing at the thrust face, so a washer is fitted here also.  This prevents the edges of the hex chewing up the oil seal once the crank spins up.

Cannot see the purpose of a washer fitted to the outer race in the housing...

HTH,
piet

Hi Piet this washer would bear against the outer race pushing the race inwards not sure of the purpose but I will put the bearing back without it and tension the nut and check clearances that seal can move in and out a bit as wel las there is no shoulder for it to sit against.
Thanks,
M.
