336 windshield replacement

[DavidC]

I am in process of replacing all windows in my 336. It had a 0.250" windshield - I am putting in the OEM 0.187" thick. The 0.25" will fit, but there is not clearance in the channels for felt edging and Presstite sealant. The 0.25" on mine was installed 100% bedded in silicone - it looked fine externally. Now I am dealing with the nightmare of cleaning the channels to restore it after the windshield was removed.

Where did you get your replacement windshield and was there any wait getting it? I'm thinking about having the windshield replaced in the upcoming annual.

I have a '77 337G, SN 1795, and the only spec I'm pulling up for PN 1513770-1 is .250" thick. The maintenance manual does not have any reference towards thickness.

So mine is a 1963 336, Windshield P/N 1413702-1, got it from Great Lakes. They said 4 weeks lead time, but it arrived in 1 week. With regards to thickness, I have found no references in the parts catalog or maintenance manual to thickness - only going by the PMA parts that Great Lakes and LP Aero sell - their windshields for the 336 are 3/16". My windshield is out of aircraft now and it is clear that the channels are not sized for 0.25 thickness with felt as shown in the maintenance manual.

Thanks for the info!

Another clue in "The great Center Strap debate!"

I finally got the windshield and vent window done. It took longer than I expected as I kept getting redirected to other projects. We got the windows from Great Lakes.

Now to order the side windows!!

Looks great Steve!

Mine need to be done, but it will be a year from now.
