'81 240 WR swingarm shim

Is the washer (no. 12 in the picture) supposed to sit between the swingarm and frame, or does it go between the axle nut and frame?
There is barely room to get the swingarm in the frame without it already.. But it looks more like a shim than a washer.

Item # 12 in the picture is to be located between the frame and swing arm. The shim is used on both sides of the swing arm, so you will need a total of two shims. No washer or shim under the nuts.

Thanks Marty. Yes, I have two shims total. I guess I'll need an outward pushing clamp to spread the frame a few mm's then, otherwise I won't get the swingarm in there.

I usually cut a length of 2 x 2 just slightly too long for the gap and use that to spread the frame.

Thanks for the tip, but I noticed I could change the clamp I have around so it pushes outwards.

A better way of doing it, you won't damage the paintwork!

This #12 washer/shim is actually a wear washer so the swing arm can't wear into the frame. I believe it's hardened.

Yes, it's definitely a different material to "regular" washers. Got them in place now!

Yes it is hardened. The shim is actually a valve spring shim used in the automotive industry. If you need one go to your local auto machine shop and they will most likely have one the correct size/thickness.

This is what happens when they aren't installed
