Tip for fixing early popouts

[Blue Baron]

The early small popout windows (pre-'65) used a thin plastic compression washer to hold the window open. These washers become brittle and disintegrate after 60 years. An easy fix is to substitute an oil drain plug compression washer, which is a perfect fit.

Most of us have some of these left over in our toolbox.

Perfect, simple, elegant, and, everyone that has owned a VW for any length of time has one or more of those drain plug seals waiting to be put into service.

Thanks for posting this idea.

I just had to deal with that. I wrapped a piece of twine around there and cut the ends off. A piece of plastic is much better to do.

How did you get the cap off to put that washer on? Did you just flex it around it?

Just take it apart.

Loosen the small set screw on the knob, unscrew the knob completely off, and the whole elbow comes apart. The washer fits between the two arms, as you see in the photo. Normally this would be a narrow flat plastic washer, but they often break or are missing. Have a safe space to put the small parts as you work. Each side should take about five minuites to do.

This is more durable than the original equipment.

I call myself a genius.

There is a tiny screw in the knob. You use a jewelers flathead screwdriver to loosen it. You can then unscrew the knob entirely off and pry the whole thing apart. The central shaft fits through a cone-shaped eccentric that holds it all in place. it's a very simple arrangement. Good luck!

Thanks Blue Baron for this and the earlier post with the photo. My pop out window always closed once I started driving. I kept it open with two velcro straps. Well today I hit a serious rain shower out of nowhere and I had to unwrap the velcro to close the window. (Soaker for me) I had marked this page for future use, but now I went ahead to fix the window. This solution, so simple, fixed the problem. Well described - thank you!!!

Thanks!

I used the copper compression washer rather than an O-ring, but the principal is the same.
