Windscreen replacement.

Post by Keith Clements »

A crew of five assembled at 9.30 to tackle the windscreen rubber replacements on John Cash and Chris Spencer Javelins. Don Bell and Neil Ord-Hume assistants.
Still and video camera were operated by Keith Clements.
Image
Having taken our time trying three methods of getting the screen in on John's car which also involved cleaning the rust off the surround and repainting , finally completing the job at 16.00 we started on Chris's car at 16.30.
Image
16.40 The inside car team ___Trim surround off, battery disconnected, horn push and steering wheel off, hidem, furflex, wood strips in recess out, sun visors and mirror removed, dash end plates off.
Image
The outside car team___ centre chrome strip off, cut rubber around chrome strip , remove chrome strip. Take extreme care not to damage the chrome beading.
Image
17.15 Glass out and clean it. Clean chrome strip. Measure centre at bottom of screen and fit rubber. Do not stretch on but cut off so there is some compression at joint. Make sure joint is cut square.
Image
Image
18.10 Now the difficult bit. It is very difficult to get the glass and rubber through between the A posts.
Feed through from inside on one side so that the bottom corner is positioned in the recess. Lever the rubber through with a pair of strong plastic blades. These are special for fitting windscreens.
Image
During this process the screen needs to be held forcibly into the recess and pushed forward.
At this stage the rubber is not over the outside rim where it will eventually sit. We are just trying to get the screen between the two A posts.

With the screen in the recess at one side you then need to do the same on the other side. This needs considerable force in three directions. 1. Levering on the rubber and glass against the A post. 2. Pushing the glass forward into the recess and 3. pushing the glass into the recess in the opposite side. Lubricant needs to be applied to the rubber. We used a special product but washing up liquid might do.
Image
We also had to apply a lot of pressure and also hit the glass with the flat of the hand to get the rubber passed the A post. I have seen the A post ground down to make the aperture larger. A lot of patience and controlled aggression will be needed.

18.10 Screen in part way sitting in the recess. Now the seal can be levered over the aperture starting at the join and moving around , doing one side first then the other.
Image
18.20 Screen in. A sealant was then applied all around under the seal. The chrome strip was fitted and it's joining strip positioned. We had to plane off some of the wood before refitting the strips in the A post. Note that the chrome strip may ooze out. If it does let the sealant dry for a few days and retry.
Image
19.00 All done with trim refitted.

Pictures to follow.

Re: Windscreen replacement -Difficult bit

Post by Keith Clements »

The 74MB video shows the difficult bit.
The first part (0 to 1 min) shows trying to get it into the driver's side rebate in the A post with a quick look at the amount of travel required on the passenger side.
The second part (1 to 3:30) shows the lubrication and bashing to move it across the flange. Continuous pressure was applied during this on the passenger side as well.
Next (3:30 to 4:30) the rubber needed to be un-twisted.
A similar process was required on the passenger side but that required even more force. Two people (one inside and one outside) pushed with adhesive gloves towards the drivers side. One used a strong thin plastic spatula to lever the glass/rubber on the A post flange towards the drivers side whilst another pushed and bashed forwards to press the assembly into the a post rebate and also use another spatula to prize the rubber over the flange.
With (4:30 to 5:50) the glass firmly pressed towards the front of the car by two people sitting inside the outer rubber lip could be prized over the windscreen flange with a metal hook.
With the rubber seal fitted and knocked home with hardwood and a mallet, it was then sealed with a gun applied sealer . Then the chrome strip was very carefully fitted.
The video continues (5:50 to 6:18) fitting the chrome joiner which needs careful pushing home. It needs to be a tight fit.
The video ends out of sequence (It should be just before 4:30) with the levering into the rebate of the passenger side. This illustrates that different issues may arise with each screen with rubber needing to be aligned before proceeding to the next stage.
