A whole day trying to get the windscreen to body seal onto the bottom piece of frame.
I have tried soapy water, oil, silicone grease and white lithium grease. I get as far as about 9 inches past the centre and no more. This morning there was three of us trying to get the seal in place to no avail. I have looked in the library and numerous posts to try to get an answer. Someone must have an easier less time consuming method...please share! Keith

Other than patience, there really is no easy method. Don't use a petroleum-based lubricant. Rubber doesn't play well with oils.

The last couple of seals I've installed I've used K-Y Jelly.....seriously....

Keith, this is a bit of what mark Evans - an MG is born, had to say about it.

John twist had a video about this. His windscreen installing guy used a hook to press the rubber into the grove. There was no sliding. You could make your own easily enough, but can also buy them

That's the way I'm going to do it next time. Yes I slide it on previously but I don't treasure the memory.

Thanks for the help. I will try tomorrow to put the windscreen together and try the John Twist way. The new tool may be here before I have the screen assembled..LOL. Keith

Keith, I watched that video and had my seal on in 25 mins just going slow and easy. its hard to see just what he is doing but start in the middle and you put the seal in the bottom of the channel first then with the back side of the hook (it's a o ring puller) or you can use a very dull wide flat screwdriver push it into the top of channel. once you get it started you will not have a problem.

Well, I am not as smart as John Twist. I used the brute force method and a lot of KY Jelly. It was a real effort.

Once the seal was 70% installed, things got more difficult. I found that I could push the seal from one end, compressing it slightly. Then move that small bit of progress along to the other end. Movements were initially 1/2" at a time but as I got closer to finish the increments became smaller.

Frustrating at first, but then I made a game of it. Eventually it was done, and a cold beer to celebrate!

Keith,

I used silicon spray lubricant and the pull and push technique.

Insert the gasket into the channel and pull it in as far as it will go, at a certain point it will stop. Now go back to the beginning area and push some gasket into the channel, push this 'wad" of gasket in and then go back and start pushing another hand full of gasket forward.

Now that you have gasket bunched up in the channel, go back to the front and start pulling again.

Add more lube and repeat.

There are projects that I've heard too many horror stories about here, that I prefer to pay for.
$65 US (labour) for clutch install & bleed.

4 hours @ $50 US for upcoming windshield install, that I spent a lot of time sourcing a good installer. I've heard too many horror stories, and too many of folks breaking theirs.

There are times it's smarter to pay. Installer will allow me to be present and help, but no way I want to tackle on my own.

Yep, me to, or similar. Took hours. I recall lying on the floor late in the evening embracing the windscreen. Gripping the heavily soaped seal with my bare feet at one end one and pulling and massaging it with my hands and elbows at the other. If anyone had videoed it, it would have gone viral. There was whiskey afterwards.

I used soapy water and a flat blade screw driver. I wasn't easy but it took less than 15 mins. to install the seal. That's all it took to mount the windshield onto the car as well. I did it without any help or the use of straps or any other crazy things I've seen posted. It's easy once you figure out how to do it. Do you think MG spent more than just a few minutes installing it when they were building the car?

Keith,

It's essential to have a workspace where the frame can be held and accessed from both sides.
I found that PB silicone spray lubricant works best. You need 3-5 people, particularly if the frame and glass are
assembled. Otherwise, screw the frame rail to the workbench. The extra hands are required, not so much for
force, but to guide the force and the rubber in a curvilinear fashion around the arc of the railing. If you just pull on one
end the rubber will bind on the sides of the rail after maybe 9-12 inches.

Ray
PS: I could never get the JT method to work.
