Hi,
    The magnet is (was- now it is chunky style) a cylinder inside the speedo
drive. It rotates around the metal spacer which is part of the speedo drive
body. The magnet mates with the metal tabs inside the wheel when installed.
I added some bearing grease and thought I had it lined up as it dropped in
flush. If you look at the body of the drive unit, there are two areas that
look like they will anchor the drive unit on the boss on the right-side fork
leg. The correct one is the smaller. I incorrectly chose the larger one. I
thought the cable (wires) were routed funny when I reinstalled. They SHOULD
exit behind the fork leg. I wish I had noted this better, but it was hours
between when I removed it and replaced it. After the magnet fragged, the
speedo drive was very slightly cocked in the wheel, but it doesn't look bad
(the plastic) inside, save for the magnet, which was easy to remove (in
pieces). Unfortunately, I am told the magnet is part of the drive unit and
is not a separate piece. It doesn't pay to hurry, even if you ache to get
back out and ride. You can bet I will not screw this up again. DUH!
