Hi Guys,

Question for you guys regarding gauges that have a foggy face. I've got a bunch of old original gauges that have foggy glass from the inside (I guess they're not waterproof anymore). Has anybody found a way to clean the inside of the lenses on these gauges? They don't come apart..........ok, maybe they do but you can't get them back together........and I think trying to drill out the glass on the sides to maybe get a brush in there would destroy it.....so I'm at a loss. It's a shame to toss out good original gauges because the face is too foggy to read. Any ideas?

thanks,
bob

I thought there was a thread somewhere regarding rebuilding of these gauges but am still looking. I'll try at SteelSoldiers and if I find it, will post the link. As they are common to all Mseries vehicles, it could be on one of the other sites.

One thing I do recall is a concern about the radium in the dial face of the older gauges. Be very careful, as you want the gauges to glow, not you. Contamination is a real possibility if you remove the glass.

Jess, I recall that post as well-it was on this forum and someone found a way to split the gauge open and change the internals to 12V. Ring a bell, anyone?
Thanks,

Found this about how to open the case and repair a WWII Jeep fuel gauge and also might apply to the M series instruments as well.

I have had luck driving out the moisture by placing them in an oven that was pre-heated to about 100F then with the oven off allowing the gauges to sit inside as the oven cools to room temp, this method worked on the speedometer I have in my truck and it has remained clear for many years but the truck is garage kept and out of the weather.

Bob, I found this topic in a post from 2012 started by a "w30bob"

Original G-741 gage lenses are not glass, rather plastic. I've seen plenty of them foggy, but it on the outside. Semichrome polish works wonders on them, clears off years of fog & scratches in short order.

Also, if you have the red dash lights that change from the front, sub type 353 lamps for the 313's. It puts the filament behind the panel where it belongs and makes things a LOT brighter.
