Re: The infamous odometer problem

[byoshida@zygote.hsc.usc.edu (Benton Yoshida)]

        I had what is probably the same problem in my currently not running
'81 S.  When the temp went up, it would stop registering mileage.  I found
a cracked gear (red plastic?) which I superglued only to find out that the
problem was still there.  I finally traced the offending gear to be one of
the metal ones (I'm not sure where anymore since it's been a long time).  I
took the gear off and scraped the inside surface of the gear and also the
shaft to increase the grip, and voila! no more odometer problems.

        I guess I should mention that I was able to find the bad gear by
putting the whole speedometer into an oven that was in the lab that I was
in.  Then while it was warm, I'd turn the input shaft and see which gear
was slipping.  You could probably do the same on a warm day or with a
household oven.

Hope this helps, benton------

p.s. any idea of the ratio of Mk I vs II cars on this list?
