Speedo drive questions

This is on late 70's WR, but I am using an '83 front wheel. Per the part numbers, the drives are the same, but wanted to give full disclosure.

1. Question on the speedo drive - The one I sourced has a hole in the center, just the width of the axle, that appears to get sandwiched between the axle spacer and right axle shoulder. Is this correct, or should the axle spacer pass all the way through the speedo drive? I'm not talking about the disc with pins in it that is pressed in the wheel, I'm talking the drive unit that the cable goes into.

2. I believe these drives had felt material between the drive and the disc with the pins on it. Any idea of the dimensions? I'm thinking it should be a hair bigger than the diameter of the disc with pins on it, with a hole in the middle a hair smaller than the axle?

Visiteur, are you saying the felt should be the size of that disc? I understand how the pin disc works, its the drive unit that attaches to the cable that I had a question on- I want to make sure the drive unit part should be sandwiched between the spacers and axle as it mates up with that disc.

You will need to pull off that larger diameter outer spacer and behind it is a smaller diameter spacer sleeve that is used with the speedo drive. The speedo drive is sandwiched between that spacer spacer sleeve and the axle shoulder. That larger diameter spacer is not used when installing the speedo. You will also need the drive pins. looks like at least one is missing.
No felt material is used. I will see if I can get a couple of pictures of the spacers.

Here is a picture of what the hub looks like after you pull off the outer larger diameter spacer. (Large spacer placed next to the smaller inner spacer in the picture to show the difference) Now you can place the speedo drive in place of where that lager outer spacer was.

Gotcha, thanks. I do have the pins, that was Visiteurs photo.
