Hi, the Speedometer in my Super 88 is not working so the first thing i did was checking the speedometer cable but it was ok...
This morning I removed the speedo to check if the inside is ok...

If I turn the side where the cable goes in, the needle should move but the copper coloured wire does not move...

Now my question is: has anybody of you dismatled a speedo completely? Can I remove the needle without any problems?
I don´t want to brake it...

Thank´s for your help!
