    Speedometer disassembly and lens removal

    Folks,

    Is there a way to safely disassemble the speedometer and tachometer to my 1978 GS1000E - I would like to clean the inside of the lenses.

    From the outside, it appears that the ring that surrounds the edge of the lens is either glued to the speedo/tach body or it snaps on. Either way, I'd like some input before I proceed as I would like to *not* break anything.

    Thanks!

    Its press crimped on. Take a small screw driver and insert it between the plastic housing and the edge of the bezel ring and twist / pry the crimp up all the way around. remove the bezel and lens. Reseat the crimp to put it all back together.

        Of the two methods, the "de-crimp" method is my preference and has to be much easier than the other.

        Takes about three passes around to loosen the ring. Go slow.

          Can someone give me a hint as to how to remove the trip reset knob without destroying anything?

            Lift up the face plate so you can grip the post with needle nose pliers and the extention sticking out the case will unscrew. A fork put under the needle will pry the needle off. But thats the last thing I like to do. I am afraid of not getting the spring tention correct when i put the needle back on.

              I don't think that metal knob comes off. I believe hole in the orange enclosure is large enough the the rubber boot has enough flexibility to allow you to pull the guts of the speedo up and out once the screws in the back side are removed.

                The threaded tube where the speedo cable connects prevents you from lifting/tilting the assembly out of the bucket. I thought abiout this but cant see any way it would work.

                    Folks,

                    The plan was to disassemble the speedometer to make sure the drive mechanism was lubed properly, etc. The more I thought about that course of action, I realized that the juice wasn't worth the squeeze - I didn't want to damage to the needle, gauge face, or trip knob.

                    So, I removed the lenses from the tach and speedo and cleaned them. I retightened (with loctite) any exterior screws and then reinstalled the lenses. Done.

                    Also, Nessism's technique of using a drift punch and a hammer works quite well - I laid the gauge face down on a towel and worked my way around the ring with the punch. This produces a nice, tight crimp that simultaneously knocks down any sharp edges.

                      I recrimp with a small pair of linemans pliers. The leading edge of the bezel isnt visible when installed into the dash so a scratch is not a big deal.

                        Look up rewinding a GS1000 speedo.This is how I did mine .It's easy.

                          I've decrimped a few but a small cut across the bezel ring with a dremel takes the ring off very easily and makes a neater job, imo. To re-install, two tiny holes with a piece of ss wire holds it all together nicely.
                          decrimping stretches the metal and it never re-crimps the same

                            -hijack alert- as long as we are on the subject of gauges, anyone know of a good match or method of coloring the white numbers on the tach red? I am running gsxr gauges and would like to change the redline from 13,5 down to 9,5. Sharpie?

                              Are these letters translucent (so the light shines through the letters)? You can get translucent or transparent glass paint at a large hobby store. Might be hard to match the existing shading, though.
