Replacing H3 Upper windshield
Posted by Tom on November 9, 2015 at 4:10 pmWe experienced a crack in the passenger upper windshield on our H3 while out west this spring. After we got home I ordered a replacement from Prevost and am finally getting a chance to replace it. The maintenance manual says after removal of the old windshield to clean with alcohol and then use Sikaflex Primer before install and Sikaflex 255 adhesive after the install. Just wondering those of you that have replaced windshields have done this. And if the previous installed used this how hard is it to get the old glass out?

Tom,
My passenger side lower had to come out last December for a fridge change out and the glass guy at Parliament worked for almost 2 hours getting the old windshield out because some nimrod put the glass in with sealant. If just the glass is being replaced and the rubber seal is good, there should be no sealant used.

Thanks Tom. No problem with leaks driving in the rain. That is the justification for the sealant I have read.

Tom…
Our upper windshield was glued in too on our 98 H… Prevost Ft Worth spend over an hour getting it out but said he thought it was the original piece of glass… he looked at the passenger side top one and it too was glued in… Of course we had to replace the gasket as well and they used no glue.
Do you think some were actually glued in at the factory?

I may not have read it correctly but my Field Service manual told me to use sealant for the installation of the lower windshields on my coach.
How do you get the upper piece out anyway? Mine is buried by a full width cabinet.

Hi Tom I did send you an email because I could not find the reply tab only to find out I was not logged in. I have been in the glass business for over 30 years. It is my experience that all gasket set windshields come from the factory with urethane glue. This is for not only sealant for water leaks but also for retension. I have seen both types of gaskets on coaches either self locking or a locking strip that goes in the middle of gasket. I also use sika products and they do not recommend any other cleaners except for sika cleaners and primmers. You can use the Sika 255 with 215 primmer and be completly fine. The only time you would need to use the sika cleaner if there was oil or grease on the gasket. Let me know if I can help in any way.

Thanks for all the replies. Thanks to Tom Young for stopping by we have the old glass out and waiting on a new gasket from Prevost. Always an adventure.

Hi Chuck, Hope you and Barb are doing well. I have access to the inside of out windshield as well. I am not sure what you would do with the cabinet there unless there is some access behind it. We would have not been able to get ours out without pushing from inside.

If you do not have access from behind any of the upper windshield you have no choice but to pry out the gasket perimeter, get a plastic flat tool behind the glass and work the glass out, starting with the curved corner I would think.
If you have access to any part of the inside of the glass you should be able push it out, but still might require the plastic tool to pry back the outer perimeter of the gasket. There is no downside to accidently breaking the glass because you are replacing it anyway and installation is solely from the front.

Ok…guess you guys are still working on getting the rest of us the ability to delete our post?

You can go to Harbor Freight and get some suction cups to help pull the glass out. Make sure you pry the gasket away from the glass all the way around. You can also get fiber sticks from Harbor Freight to help pry the glass out. Start in the upper corner put the suction cup on while holding outward pressure use the fiber stick to pry the glass out from the corner. Once you have 12-15 inches out it should go quickly.

Tim,
Relative to post deletion we have had discussions and as of now our thinking is as follows:
The author can delete his post within a short time frame after posting, such as for a duplicate or a change of heart regarding his post. But after that time frame has elapsed we think we want the post to stand. The reason discussed was we may all make posts we regret, and then a constructive discussion follows, but because of second thoughts we delete the post. Then we end up with a discussion that might end up being out of context and nobody reading the subsequent posts understands what is going on.
We can delete anyt thread or post so if a post is needlessly harmful to the author we will probably delete it at the author’s request. We have had some threads that were a little painful, but they were so instructive a greater benefit came from leaving the thread and posts stand. Don’t forget, unless the discussion gets out of hand with personal attacks with no basis, inflamatory posts regarding sensitive topics like politics or religion we probably are not going to participate in censorship. That was one of the hot buttons our members had from a previous site and we do not want to stifle discussion. But it won’t hurt for authors of a post to realize they should think before posting.
I don’t know if our web guru has put the deletion mechanism in place yet.
