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

n86121 · #1 07-19-19, 04:11 PM

Good evening all,

I am seeking answers and truth BEFORE disemboweling the interior of my 337.
To determine if said disemboweling is even worth the hassle in the first place.

The T337 has double side windows, inner and outer.

QUESTION: Can anyone give step-by-step instructions/guidance/photos on replacing the OUTER side windows on a T337?

Yes, yes, I know
you pull the inner trim fairings and the inner windows pop right out.
All well and good. That's easy.
As 'they' say, "Duh..."

BUT....I am CONTEMPLATING replacing the outer windows, which are surrounded by scary rivets.

While attempting to polish same, it appears there are vertical 'frame' pieces front and back of each window that simply unscrew. By (simply) removing those pieces do the outer windows (with frames) pop out, or must one de-rivet the 10,000 scary rivets to get the outer windows out? (And therefore same to put back in, then repaint, then...etc.)

Maybe same for P337?

Then of course, any thoughts on the installing outer windows into their 'frames?'

Muchos gracias 'thrasher amigos,

Hi David,
I will send some pics after the weekend on the side windows. There are a couple retainers that you have to drill out the rivets on to get the two aft side windows out. Not as bad as you might think though. Some of the retainers unscrew, but my memory serves me, there are a couple retainers that need to be drilled out to remove easily between the two windows. I have removed mine, and just waiting on installing at the moment since the temperature in South Texas is pretty hot - and it is nice to have the windows out as I finish the work and wiring on the inside of the cabin. I am replacing all the windows in the aircraft.

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.

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
