Hi,
Both screws holding the tach face in place have come loose and are rolling around the bottom of the gauge. I was given advice to remove the gray panel between the gauges to access a screw that holds the glass in place.
So I tried to remove the grey panel between the gauges. No luck. Looked around the back and couldn't access anything because of it's location hugging the headlamp.
Disconnected the panel

Flipped it over and found four nuts. Removed them.

With the nuts off am able to push the tach up out of the housing.

Pushed the weather tight rubber seal down to expose the edge of the glass housing.

At this point I tried twisting or prying the black rim around the glass off. No joy. It feels like it is one solid piece. There is no play in the black ring at all.
This is the back, no obvious screws or attachments.

This is a look at the rim from the back. The plastic under the black rim is smooth all the way around except for those three tabs. Where the rim meets the smooth plastic there is no gap. But there is a slight gap (razor blade thin) starting over the left tab and extending to the right tab.

These two pics show it a little better. First is with a flash, the send without.

I slid a razor blade in the gap but didn't put any pressure on it. I'm sure I can pry the black ring off by leveraging in that gap but I'm also sure I'll crack the rim doing it. Does anyone know how to get into this damn thing?
Thanks,
Josh

The gauges in question are an older design. If I remember correctly the three brass colored slotted thingys in the middle hold the cluster together.
Google "remove gauge bezel" lots of articles on how to remove it, thing is even if you do not destroy it getting it off your never going to get it to look like new after you put it back on. It is do able though.

Ute,
Thanks for the link but unfortunately my clocks come apart in a completely different fashion.
I think I found the answer. I don't like it.

That sucks.

Before cutting I would try unscrewing those 3 brass jobbies in the back of the tach........
Spike,
I did. They don't loosen it up at all. I believe the plastic bezel is either snapped on (and I don't know exactly where to push to unsnap it) or glued on. As soon as I find someone with a dremel I can borrow I'll be cutting.
Josh
generally they are glued on. the glue they use also acts as a seal.
SOMETIMES a heat gun will melt it enough to pry it off. it really depends on if the glue is thermoset or thermoplastic glue. in either case.

Yep, I remembered wrong. Dremel or other cutting tool
If cutting, I would be inclined to use a jewelers saw with a fairly fine blade or a coping saw with as fine a blade as possible. It makes a much cleaner cut.
