New game - ID this part!

tomspro · Dec 23, 2014

I am not easily embarrased when it comes to my Norton knowledge - and lack thereof.
No trace of Jim Comstock genes here!

So I have been working on upgrades to the old beast and making good progress.
Persistent leaking of oil from multiple places started the project, and now it has taken on a life of it's own.
Renewing seals, replacing primary with a belt, oil tank and tranny redo, new sprockets & chain, etc. Even got a new paint job (thanks Brett!).

But... after sorting things in the primary, discovered a rather substantial part that is without a home.
Perhaps I replaced it and do not remember.
Perhaps it needs to be installed where it belongs.
Dunno... but here are pics.
It measures about 1 5/16" OD, 3/4" ID, and 1/2" thick. One side is clearly worn, the side with the recess looks good.

I think its the Alternator/ rotor spacer. #31-060402

I'm thinking it's #54 that should go over the clip ring on the input shaft of the transmission. http://www.oldbritts.com/1973_g10.html If I'm correct, you get to take the clutch and primary drive back apart.

Better yet! #31 on http://www.oldbritts.com/1973_g10.html That way, you only have to pull the rotor.

+3 on alternator rotor spacer.

Second guess is the spacer that goes over the clip on the main shaft.

Def NOT 06-0747 that goes over circlip on transmission shaft. Been there...done that. (and that spacer is not this thick)

Now that could be it!
Maybe not needed when changing to a belt?
Things seem to lined up proper on that shaft.

I found that spacer to be incompatible with my beltdrive conversion. Hopefully you have the dual gearbox adjuster or atleast relocated the single one to the primary side.

Yes - new gearbox adjuster has been installed on the drive side.

The dirt on that part is driving me nuts!

now worries. that is how it came off, and it is no longer needed (thanks for the ID guys) so why bother...

You might consider rotating the stator counterclockwise a bit. Edit: Upon closer inspection you seem to have it in the right spot, my bad.
