changing bronze swinging arm bushes to needle races

[mauricejota7604]

Hi gang I am just in the process of replacing the worn out bronze bushes with needle races in my red 3C I have a question for others that have made this conversion, the machined section in the swingingarm where the bushes sat is deeper than the needle races so the little shims that should sit behind the race and the step in the swingarm will float around and the race will not be sitting hard against a shoulder any ideas??

Don't worry about it, all the shim does is hold the spacer in line.

Longer spacer?
Did mine over twenty years back and the lot was sold to me as a conversion kit.

So it doesnt matter if the needle race isnt hard against the machined shoulder inside the swinging arm tube?

No, all of the clamping force goes through the bobins and the spacer and the nylon shims take care of any side load.
Just push the needle bearing in until they are flush with the end of the swing arm axle tube.

You will see why it doesn't matter when you try to press the things in, and even moreso if you ever have to get them back out
