Specific steps to replace (outer) side windows - de-rivet?

[B2C2]

I am also interested in working on the windows on my 1969 T337D. The outer windows seem pretty good, but I have some crazing on the inner pilots side window and there is a leak between the inner and outer windows in a few spots so there are streaks in there from the occasional outdoor rainstorm the plane gets (its usually hangared) dragging dirt into that space. What is the seal arrangement between the inner and outer windows and can this be repaired by just removing the inner windows? Also can you confirm that its a simple matter to remove the inner windows, maybe post some pictures of the inner trim removed. I am thinking of replacing the inner windows and replacing the seals at the same time for my next annual "while your at it" expense.

Lots of info on the windows in this thread, let me know if you have any other questions

i looked through this, but cant completely figure out the answer to my questions from the posting. Is it possible, on the 1969 T model, to remove and replace the inner windows and seals without drilling out external rivets? If it is where do people suggest getting the replacement inner windows and seals?

You should be able to remove the inner window with just one small piece removed by drilling out rivets and this may not be on all windows. The rubber seal is placed around the plate window and then the window is held in place by the channel and the seal is pushed against the outer plate window. Should be pretty easy to do. The new inner window with the seal around it fits in place where the old one comes out. There may be one riveted plate that might have to be removed on some inner glass but that is really easy to drill out the rivets and then just pull new ones in. You should only need to remove one piece off one side and pull the glass up out of the channel.

Basically just remove only what is necessary to remove the old window and then put the new plate in with new seal just like you removed the old plate

The first photo shows the finish with the new inner glass in place with the rubber seal and window in fixed channel
The second photo shows the inner glass out and the channel that secure it in place
The third photo shows everything out including a small plate that is riveted

thanks for the clarification. Where did you source the seals and the new windows?

In may 1969 T337D, you

1. Pull out the side trim pieces, and
2. The INNER windows just have rubber seals around them*.
3. The seals just sit in simple press-in frames.

No riveting, no hassles.

For turbo/double windows you want the window rubber gasket to be non-symmetric, to maximize the distance between inner and outer window. Otherwise with vibration they will rub / haze at point of contact.

awesome thanks for the help. I have a 1969 T337D so that's perfect. I am going in for annual in two weeks, assuming no major issues, I will tackle this as a "while you're at it".
