One day while riding my 1981 Honda GL500 I had the miss-fortune of having the screws that hold the dial face of my tachometer un-thread themselves after 29 years of vibration and cause the face to spin around freely inside the case. Unfortunately the case is not simply screwed together, the front and back halves are held together with a band that has to be removed to split the case apart to fix the dial face. So that is what this instrucatable covers, how to remove the band and take the tachometer apart as well as the speedometer.
This should also work for the Honda CX500 as it uses the same units as well as the early Goldwings and 70's through early 80's CB series bikes with the same style tachometer and speedometers.
Step 1: What you need
- Tachometer or speedometer that you want to take apart for some reason
- 1/4" flat bladed screw driver with a tip that comes to a fairly fine point as it will have to get under the edge of the retaining ring to pry it up
- and a pair of pliers
