Side windows + rubber + channel

[inaglasshouse]

Hi all,

At the bottom of the (911 coupe) side window, it fits into a rubber U-shaped bit, which in turn fits into a metal channel that engages with the window lift mechanism. Seems a pretty tight fit, or might be glued in.

My question is: does anyone have any hints and tips for how to get the glass out of the channel without breaking anything?
And the same question in reverse when re-fitting the glass + rubber into the channel - any words of wisdom?

Many thanks in advance for any help the DDK collective brain can offer.
Richard.

Don't think it's glued. I would imagine gentle spreading of the metal channel along it's length with a broad implement will have it release it's grip on the rubber and thus the glass. A spray of lube (WD40) would have the rubber loose as it might have some sticktion on the glass.

Two stiffish breadknives?

Richard,
I tried liberating the drop glass from the lift channel and had a very difficult time of it. I used a break off type bladed retractable knife. The blade can be extended sufficiently to get it between the glass and rubber and between the rubber and the metal channel. Repeatedly running the blade along the channel finally got the glass free.Took me ages. Fortunately I do not have to reverse the job as I am using Lexan for the glazing and if anything the fit requires a bit of PU.
Before removing the glass from the channel you need to mark the position of the glass relative to the channel. (photograph and measure) This enables fitment of the glass in the same position later.
Good luck. Kirk

Bitch of a job from my experience.
Mine (73T) were actually glued in but I doubt that was a factory process.

I find separating these kind of things need heat (ie very hot water) and allow the rubber to 'ease' itself away by application of some pressure or force held constantly and the parts slowly ease away from each other.

Measuring the position is a must!

Re-assembly is hot soapy (Fairy Liquid for example) water and constant pressure to ease the parts together until fully seated.
That solution will dry and the grip will be good as you well know when you took it apart...

Thanks all. Another fun little job!

Heat is your friend - either using a heat gun or very hot water as suggested above. As I recall there was some glue involved but the heat releases it.
