windscreen install - FAQ needed

Post by garyinwestoz »

I reckon an FAQ for windscreen install needs to be made up.

From what I can gather on various forums, the know how do it on our cars is disappearing, due to modern glass being bonded in.

I found this series of youtube video of a 2002 windscreen install that maybe helpful. I've added a written description which follows this series

Vintage at the Vineyards 2008 - Windshield install demo part , 1, 2 + 3

note * denotes extra steps added by this (firstfives) group

1. Install rubber gasket

Place glass outside down on a firm non scratching surface - maybe a rug or something - bonnet works well too.
orientate rubber gasket correctly,

then
install rubber strip to perimeter of glass, ensuring glass is fully embedded into channel. Start at lower corner and move towards top corner then across the top. Tap around edge with hands, to ensure full embedment

Take a long length of rope or cord ( probably 6mm cotton rope x 6 metres), and insert middle of length rope into bottom corner of channel in top face of gasket. Slowly work rope into channel along the edge and bottom ensuting full embedment, work aroudn corners adn acroos the top and other side.
Cross over robe along the top ensuring full embedment and min 600mm over lap - leaving about 1000 mm of length at each end.
spray rubber gasket and rope with some lubricant ( widnex?)


2. Fit glass to car body

[youtube][/youtube]

Pick up glass and place over car frame, locating the bottom over the flange and checking its centred over the frame.

Working from inside, slowly pull an end of the rope, peeling the gasket to flip over the metal flange. Have someone on the outside provide a little pressure to ensure gasket and glass stays in place.
Work up one side to the top corner
Then take the other end of rope and work along the opposite direction, across the bottom then up the side
check gasket is fitted nicely along bottom and top
slowly peel ends of rope across the top
double check fitment, use a plastic edge panel tool, to pullout rubber gasket - push in roof lining as required to full perimeter.

then

* insert a good amount of windscreen sealant ( no hardening kind) to the channels ( ie body side and glass side) as an added waterproofing precaution.



3. Fit infill strip

[youtube][/youtube]

Insert bottom infill chrome strip along bottom channel .... how...??? and corner eschucheon plates.


using special tool https://www.gettoolsdirect.com.au/lisle ... gJAsvD_BwE

Starting at corner adjacent to corner eschuteon plate insert chrome strip with tool already in channel, fully lubricant rubber channel to aid slipping of tool.
* ie cream waterless hand cleaner so can easily hose after wards, without leaving a messy residue.

Work slowly up sides and then across the corner then along the top and down the other side. Keep free end orientated flat so infill strip doesn't twist. A fair amount of force maybe required to move the tool along th channel.
Stopping the tool may cause a nick in the chrome infill - so be aware!

Cut end of strip to required lenght. If the strip you have is too short ... well I dunno!!


hope this helps

I'll be replacing the gaskets on both the windshield and rear glass. I'll obviously, take pictures as part of my Eleanor rebuild. It's going to be one of my projects in the very near future.

Oh, one other thing Gary, I'm bookmarking your post for when I do my windshield and rear glass. I'll be sure to give you credit for making my job a lot easier :D

Good, but missing a critical step. You need to inject sealant between at least the body and the rubber, that's what the big blue book says, but I also do it between the glass and the rubber. The original stuff is kind of a non hardening putty. Use 3M 08509. It's gooey and sticky and you'll end up wearing some of it, but it's good stuff, never hardens and works perfect. Some of the hardening ones will seal ok, but look out if you ever have to remove the windshield again, you'll have to cut the rubber out, trying not to cut the paint, then somehow get it off the body before you can reinstall with a new rubber. Not wanting leaks I squeeze enough in there so it starts to ooze out, even more so when I install the lockstrip. Cleans up ok with paint thinner.

For installing the lockstrip I use cream waterless hand cleaner. Slick as snot but water soluble so it just hoses off.

Mike I can edit the original post - where abouts in the writeup ought this sealant stuff go.
Ive added a * in the first step as my thought.

Im kinda unsure when the goo ought to go in , given the requirement of using a bit of rope to get the channel lips to lock over the metal flange on the chassi opening.

Not my idea, it's something I saw somebody use long ago, but yes, Genius.

You inject it after the windshield is installed, so no complications with the rope.

This will surely save lots of time and effort for future windscreen jobs. We'll check if uncle's new E12 project needs a windshield job to address the learning. We'll just finish installing the set of wheels from 4Wheelonline onto his Silverado before we can take a closer look at the rubber strips.
