S90: Speedo Repair, Part I

Unfortunately, the speedo isn't designed to be easily disassembled.  That doesn't appear to stop anyone, however.  Trouble is, you literally need to peel the metal lid off the main housing centimeter by centimeter.  It's almost as if you had to remove the lid to a pickle jar - except you can't do it by unscrewing it.  Instead you have to pry the metal up all the way around until you can literally pull it straight off.

It would probably be easier if you had the exact right tool for the job (not sure what that would be, though).  But I ended up having to use a large flathead screwdriver.  I'd work the tip under the metal lip and pry just a little bit up, then just repeat that down the line.  But the rounded edges of the speedo were difficult because it was hard to get any purchase under the lip.  This job just took time and a lot of patience.

Once the cover seemed almost ready to come off, you have to get some leverage and pry it off.  I was conscious of warnings not to ruin the glass face.  Unfortunately, it's hard to know exactly where your screwdriver tip is the first time you're doing it and I ended up putting a couple of gauges in the glass.


Poor lighting on these pictures, but you can see the metal lip being pried up little by little.

After a working all the way around the perimeter, this is the lid about ready to be pried off.
