Restoration Yamaha LS3 1972: speedo gear Yamaha

The original brake shoe plate of the front wheel had a broken cable holder that was glued together a long time ago. When I tried to take the cable adjuster out, the holder fell apart.

I could try to repair ir but I found a nice cheap NOS one on Ebay.
All the parts inside the old brake shoe plate were still in good nick, so all I had to do was take it out and fit it into the new NOS brake plate.

After removing the brake shoes and brake camshaft I took a nice round spanner and carefully pried out the seal.

After that it was a matter of removing the circlip and you can take almost everything out.

Almost, there is one thing you need a special tool for and that's the speedo gear. It's screwed deep inside the brake plate and you cannot remove it with a screwdriver or "normal"socket.

As I didn't have the "special" Yamaha tool I made one myself. A 32/17 socket fits perfectly in the opening, so I took one from an elcheapo set I had lying around, took some measurements, put it in the vice and shaped it so it would fit in the gear's bushing.
