I have two speedos on my operating table, wondering how I can dissect them both. One is my original Evo in mph, the other has a kph/mph dial. I would like to swap their dials over, so I no longer have to guess what our road speed is, when we're travelling sur le Continent.

It looks as if the dials will interchange, as they are both held onto the body of the instrument with just two screws. While the screws should be easy to remove, I have had an exploratory tug at the needles without success. I don't want to wreck the darned things, so has anyone had success getting a speedo needle off?

It looks to me as if there may be a locking device underneath the needle, but I hesitate to push my luck and wreck things! The metric speedo is a NOS and wasn't cheap.

 

Graham, Why not just take a photo of the metric, load it into the computer and using photoshop, etc enlarge it until it is the same size as the original. Then cut it out and paste it on the original?? You may have to cut a slit to get it over the needle, but done carefully it would be hard to tell the difference. We did this in the past on some older bikes that we restored. Hope this helps.

 

The 3 or 4 speedometers I have dissected over the years all had needles that just pulled off. Hopefully some joker hasn't been in yours before you and used super glue to reinstall them.
Do you have any speedo shops around you that you can talk to for guidance?
I am never comfortable tinkering in those things.

 

I've taken apart a lot of GM instrument clusters and I use a dinner fork to pull the needles. If you can determine yours are pressed on (I'm no help there, I'm afraid), run the tines of the fork under the needle hub and rock it back and forth to work the needle off the shaft.

Works on cars. May work on the bike too.
