You have to heat it up in really hot water, then bend it to get the gauges out. They do come out, but you may need to "help" them with a flat screwdriver too.
Now, if the rubber is really old and hard, you may want to silicone it really well and let it sit for a few days, then try the hot water again.

Mark, if you can get them out successfully, you may want to get some oil of wintergreen to soak it in: en.wikipedia.org/wiki/Methyl_salicylateThis will actually do a better job than the silicone grease to revitalize it... As PY sez, Just sayin'  JB |

You know, thanking about it, if you have a few bicycle tire levers out of plastic (the new ones are plastic), that would probably be better for prying out the plastic gauges than a flat screwdriver.

Maybe a shoehorn?

A dip in boiling water will work: wear some gloves though, when pushing the parts out!

Mark, are you going to restore he gauge lens? I posted a thread on how to do that on VDH several years ago. Hi Herman. The console was attached to a reg I acquired and is not something I really need or wanted. However, I figure that as long as it is here I'd give it a go at trying to clean it up. I can always stick it on one of my spare regs I have for visiting friends to use. If I screw it up I won't feel bad tossing the whole thing. Do you have the link to restoring the lens? Couldn't find it. Thanks. Mark |

...Do you have the link to restoring the lens? Mark I like scrubbing powder and then toothpaste, and lastly I rub it really hard with suede: I've been able to pull a nice gloss out of them that way... JB |

I can't find it either. I think I still have all the photos so I can repost it.
These face plates are plastic and the major damage is internal (with some external obviously). As best as I can tell it is some kind of chemical reaction with the dial material. Unfortunately, the damage is too deep for a simple buffing. I had to remove a good bit of material to get it cleaned up.
As I recall, I started with 800 grit sandpaper to get the face down to clean plastic, then swapped to 2000 grit (all wet sanded) to get a uniform gray haze on the plastic. That done, then I switched to auto buffing compound and pads on a dremel tool to remove the gray haze and get it back to clear. Nex time I would try the plastic headlight cleaner as it's made for just this kind of thing. It is best if you just work on the inside first since that is the most damaged side, a few scratches on the outside face is not really a big deal.

Meguiar's PlastX works well to polish out the scratches. This is the stuff you use to clear up the old plastic convertible car windows. I've used it to polish w/o sanding, and after the fine grit sandpaper treatment, as well.
I don't remember what product I used on the inside of the lens, but something like the Goof-Off that comes in a spray bottle (NOT the industrial strength stuff in the little can) took off the coating on a couple of my SPGs w/o using abrasives. They weren't too bad, so maybe that won't work for heavily affected lenses.
