Hi All,
A dumb question from a newbie. Are the canopy rollers the same throughout the AT-6 series?
I'm starting a static restoration of an AT-6B and the canopies are pretty sticky. Looked at the T-6G parts catalog and I'm assuming I need 2 sets of 8 rollers for the two sliding canopies, if these are the same for the B.
Looks like Lance is about the only source out there, right?
http://p51h.home.comcast.net/~p51h/at6b/index.htmYour airframe could be put together from different parts looking at the photos.
Its listed as a B but has an Instrument panel and electrical box below from a later series. B was 12 volt and the installed electrical box is for the later 24 volt models.
The point is a factor that really influences how easily the canopies move is the alignment of the rails they slide on.
I would remove the canopies, remove the rear metal aft of the rear seat, which also has rear stops for he back canopy. Slide the back seat canopy to the rear off the tracks.
Remove the middle canopy by removing the screws that secure it and pull it up with the front canopy full forward.
Remove the latch on the L/H side of the front canopy and slide it off its tracks to the rear.
Remove the screws that hold on the rollers, there is a roller and a bronze guide for each, keep these together. Clean and polish up the surfaces were it rotates.
Reinstall with the bronze guide in the same location as you removed it as the guide slot will wear in with use. If you rotate it you will have to wear it in all over again.
Use new hardware on the rollers if it is rusted.
Clean the rails of old grease and paint and gunk.
If they dont slide easily when you reinstall then the rails aren't installed properly. There are shims under the whole upper piece that runs from firewall to tailcone that the canopy rails attach to. Since they are slightly angled inward the shims adjust the position of the canopy rails in small increments inward or outward.
In my Bald Eagle Thread a couple years ago I had to change the upper rail on the SNJ here. There are pics there that might benefit you.
Good Luck
