Removing windows

Post by Edandnova »

Hi, just joined the group here and can't seem to find anything on removing and reinstalling windows. Any guidance would be appreciated.

Hi and welcome,

Our era windows (presuming you mean the coach windows) are typically what is known as "clamp ring" windows. This basically means that rather than being held in with screws from the outside that go into individual holes in the coach body, there is just the one big cutout. The window (complete with outer frame) is put in place from the outside, then an interior "clamp ring" goes on the inside and screws go through that and into the outer window.

Hence, to remove, you remove the inner clamp ring (which is easily visible inside the coach) and then the outer window is free to come out.

I haven't removed my Chinook windows, but have removed other clamp ring windows.

I see a previous owner has caulked the top of each window with clear silicone making me think there was possibly a window leak. If a window is leaking is the probable cause the gasket that goes between the window frame and the coach?

Yes, I'd say so. It's normal to "re-bed" ports and windows on boats every 10-15 years or so. Doesn't seem as common on RV's but then many of them are nearing end of life at that point.

The silicone band-aid will likely be the biggest headache. It probably didn't stop the leak but can be a bear to remove and even after it looks like it is gone a contaminant film keeps anything from sticking. There is no great way to remove it - you can test to see how you are doing by seeing if water beads up (bad) or makes a solid sheet (good). At least it is beyond the window sealing flange area (whew!).

So to re-cap:

1) Remove silicone as much as possible without damaging window frame (don't sand as that will spread the poison). Curse :twisted:

2) Remove window. If there is any damage or factory goofs, assess/repair.

3) Clean sealing flange of window and same area on Chinook (keep silicone area segregated; don't use same tools, cloths, etc.). Make sure they are flat and very clean.

4) Mask off areas that are not under flange (or clean up right away as applying).

5) Choose bedding method and apply to inside of outer window flange (no open-celled foam; no silicone).

6) Push window in and tighten appropriately. Tighten clamp ring.

7) Clean up.

Note: Contrary to how I see a lot of RV's, there is no need to plaster bedding compound outside, around, or on top of the flange. This attracts dirt and can actually make pathways for water to get in. I mean, would you put antibiotic cream on top of a bandage? With a good flange, all bedding goes under it. Chinook did this well originally.

You sure have been thorough with your response. Really appreciate the advice. What would you recommend for a bedding compound?
