Since I've had the TR6' on the road the dash gauges alway seem to fog up for a while then finally clear out after about 20 mins. of driving. /ubbthreads/images/graemlins/tongue.gif
I checked all the heater hoses and coolent hoses and even the heater core and everything seems very water tight...

this seemed to be the case with my GT6 also. /ubbthreads/images/graemlins/confused.gif

Any light on this subject would be greatly appriciated /ubbthreads/images/graemlins/grouphug.gif
 
Same thing used to happen to me when I lived in humid climates. Let me guess you keep your Triumph's in a cool (relative to the outside) garage. What is happening is the cool gauges have air trapped in them, when you take the car outside the water in the air condenses on relatively cool glass. As the gauges heats up from being outside and the air equalizes, the moisture disipates. Only way to fix it is to seal the gauges very well while in a very dry atmosphere.
 
When I remove the glass what type of sealent do you suggest?

I belive the original was some type of black mastic... /ubbthreads/images/graemlins/thirsty.gif /ubbthreads/images/graemlins/england.gif
 
While you have them apart, try treating the back side of the glass with some Rain-x anti fog stuff. or one of the products that motorcyclists use to keep thier visors clear.
 
Yeah my gauges are apart right now and I am unsure if you could adequatly seal the gauges, because of air coming from the back of the gauge. I think the rainX is a great idea, and with that in mind, you would not want to seal the gauges with any compound, in order for the gauges to "breathe".
 
I've never sealed them. I think that the original black stuff was more of an anti-rattle gasket. I've put "O"rings in there before.
 
These were just black rubber, thin, round "O" rings. The fit between the glass and the chrome bezel. THat's not what was in there from factory, but it seemed to work well.
I think a well cut piece of rubber gasket would work well too.
 
The gauge O rings are offered on a regular basis on eBay. Not expensive but very useful. If I'm not wrong they are designed to be an anti rattle devise rather than a seal. If I'm wrong someone will correct me. They are not very expensive.

Most hydralics or specialty tool and fastener shops have a great selection of "oh" rings.
The humidity or condensation in the gauge glasses makes me think that the dash or seats might be a little sweaty at the same time ????
-Or- Maybe your just like the rest of us, Breathing just a little heavily, leaned into the dash,foggin up the gauges, crankin her over with the fingers crossed.... You know, just another "prep" for the pleasure of driving
 
Bearing supply houses are also a good source of both seals and o-rings. They would also have custom o-ring kits where you can buy the diameter you need and cut the length and glue the ends.

Also, companies that manufacture them usually have size charts and explanations of the different materials they are made from like Viton, Buna-N, Neoprene, etc.

This is one such site. o-ring site
 
I found some "O" rings made out of neoprene and slipped them into the gauges behind the glass. This seemed to be the key, It really does the trick.
thanx everyone! /ubbthreads/images/graemlins/driving.gif /ubbthreads/images/graemlins/hammer.gif /ubbthreads/images/graemlins/driving.gif
