Got my gauges done, here is a full run down of the process as requested.
Here is what they looked like when I started.
These were fairly easy to open up.
Started by clamping them to the bench and hitting the outside plastic covers with a heat gun and used a small flat blade screwdriver to get the crimped edges up. The edges are old and brittle and pretty much broke during the process but that’s fine because they don’t need em to stay put because the metal housings are still a snug fit in the plastic covers and they get clamped in place when mounted (reproduction covers don’t even have the crimped edge)
After that I pulled the guts out of the speedo and gave em a good cleaning, greased or oiled all the moving gears as needed.
The speedo is unique in that it uses a silicone oil in a dampener to keep the needle moving smooth and not jump around. Both my speedo and tach were in great shape mechanically so they didn’t require more work than a good cleaning.
As shown above, the plastic housings were sanded and polished.
I only had to replace the rubber insulation boots for the lights on my tach which consisted of clipping the wires, working on a new boot and soldering the wires back together. I didn’t get any photos of the process but I think you get the idea.
Then it was time to re assemble. I got new faces, jewels and light boots.
I used some CA glue and activator to secure the jewels in place and then, put my light boots on and screwed my faces on, using a bit of blue thread lock on the screws.
After this I needed to touch up my needles and Testers Fluorescent Red is a perfect match. (Back side of the needle had some original color left)
Pushes my needles back on and double checked my how they functioned with a drill and old cable cut off.
Popped my plastic covers back on and that about sums it up.
Quite happy with how they turned out. I am still missing a few small rubber bits but they are on their way as is the main rubber for mounting.
***I used a soft bristle brush and purple power degreaser to do all the cleaning of internal parts and metal housing. Turtle wax chrome polish that I’ve had for at least 15 years for the back cover.
And if there is anything I missed, or questions I did t answer, just ask.
