MG MGB Technical - quart-light rubber seals

Thought I'd attempt to replace the rubber seals on the vent-windows yesterday as they had perished badly and leaked. What a sod the job is. On one side it wasn't too bad at the pivot bolt sheared cleanly off allowing me to dismantle. On the other side I had to resort to the use of a grinder it was all so rusted up. Couldn't get fittings off even after snapping the bolt. Anyway pivot bolts etc should hopefully arrive today to complete the job. I found a very useful write up about the job at:- http://www.mgexp.com/article/vent-windows.html

Surprisingly I found it harder to remove the old rubbers than fitting the new ones. I did warm them in warm water and smother in washing-up-liquid though.

Should be picking up the rechromed bits tomorrow, then embarking on the reassembly. I got the glass out by just easing the top and bottom parts of the frame away from the glass slightly, and they pulled right out, little more than hand pressure.

When I did the glazing seals on the roadster I got them in OK, but they started oozing out. I left them clamped up for a couple of days and they have been fine for the past 23 years.

Well reassembly not so easy. As I said the new vent window seals went in a treat but after fitting the new pivot pin in the quarterlight itself getting the rubber that holds the glass in is a complete swine. Fighting with a piece of glass is a bit frightening! Tried washing up liquid but can't get it fully home.

You will need to clamp it between two pieces of wood (to protect the frame and glass), slowly squeeze it together, and leave it like that for a couple of days. Washing-up liquid is not good in this case as it will make it easier to pop out again until it dries out. But may get slippery again if it gets wet!

Thanks for the advice. Managed to use a black and decker workmate to force the glass into place by gradually increasing the tension over time and as you sadi left clamped for a day. Got the offside assembled and door built back up. The offside is now clamped and ready to fit tommorow evening when I get up. (working nights at the moment)

Still waiting to pick up my parts, should be mid-day tomorrow now!

I'm told that Kero (paraffin ) is good for assembling the glass. Lubs on the way in and then dry's out.

Picked them up this afternoon. I can forgive the mucking about, the results are superb. Castle Chrome in Dudley West Midlands if anyone is interested.
