I have a pair of the 914 euro driving lights that need the reflector re chromed. The lenses are "glued" into the reflector similar to the 7" H4's. There is no rubber seal like the 914 fogs. Anyone successful in separating these?
Thanks in advance, Brad Mayeur

Brad,

I've not done them myself, but you might try finding the appropriate solvent for the glue/adhesive used, then dribble it around the rim to soak in, set for a day or two, & soften the glue/adhesive before prying them apart.

Since you're restoring them anyway, it won't matter if the solvent also removes paint &/or the reflector surface.

If you can find the typical type of glue/adhesive from the old specs - SWAG wild guess otherwise or if done by a DAPO later - then you can google for the solvent to use with that type.

I'm blanking on his actual name or screen-name, but the member with the Caddy Shack movie photo gofer & caddy/Bill Murray as his avatar pic on the left of his posts is a chemist, & may have some ideas on solvents if you PM to him.

Good Luck!
Tom

they were sold as a glued assembly and no longer available Maybe mitelmotor would have some new old stock?

Brad,
New ones available on Ebay. They are chrome though. Hit them with a little black Plastidip. $350 shipped. Look up Hella 118 for Porsche 911.

Brad, I just did this...pre-heat the oven to 300 degree F, once hot, let them heat soak for 15-20 minutes.

You of course will need gloves, and appropriate work clothes.

C A U T I O N !

I WAS NOT WORRIED ABOUT SAVING THE OFF COMING LENS!

It was sand blasted from the track!

Once heat soaked, use a small sharp object, I used a small common screwdriver to get a small separation started, then worked in a dental spatula and went around the lens as it came loose.

Heat gun to get the rest off, small fragments of glue/glass that stayed behind.

Just waiting on my new ones to show up!

I need a new set of sealed lenses for a 1972 914-6 we are restoring. Anyone have a set? As you can see these are whole but well sandblasted over the years

914Rubber has replacement lens.

the euro lenses are bigger than the usa style, and at one time the lease reflector combination was made as one piece, that is what I am looking for

Good to know. Learn something new everyday. Just a shot. 914Rubber sent me the wrong lens when I order new fog lens for my 914. They were bigger diameter than my fogs.

Not the complete sealed beam, but yes they do have the correct lens:

and the rims have a larger hole in them to fit the larger lens. Really stupid that Porsche did it that way. We make the usa style glass lenses fluted, but not enough demand for the euro lens with reflectors and ring that would have to go with it.

Brad,
I was able to remove the glued 118 lenses by heating, then using a hooked dental pick. Slowly worked it around until it popped loose.

Posted by: Mikey914 Jan 16 2019, 12:22 AM

What is the diameter? I may have some.

You can remove them with a big hammer!

Oh, you wanted to use the bits again afterwards?

.... nevermind ....

Thanks to all!
I have one filled with lacquer thinner and I've heated one with a commercial heat gun. The lens looks to be about .2mm smaller than the lip on the reflector. Really hard to get a tool between them without risking the (really nice) lens. I would love to put these on 3 of my "drivers" They look and work great. Brad
