Window track rebuild

Window track rebuild

Postby smokinjoe [OP] » June 18th 2020, 5:17am

So not the track that the window travels in (although I just rebuilt that by riveting the failed spot welds) but the track that the window sits in & is "permanently" adhered to. My old base track rusted out while on vacation last summer.

I got a used window by the skin of my teeth but still have my old front window glass which is fine but the base track is gone. I still have the lower track that the regulator rollers ride in but here is the mechanical dilemma. How to fasten these 2 tracks together? No room for the rivet gun to rivet them (unless I cut out a spot for the rivet gun).

I will post pics of the pieces tomorrow (its past midnite here)

Someone must have dealt with this problem beside me....

OK so picture added to show the 2 pieces I am trying to join. Top one is now aluminum to avoid it rusting out again. I think they were spot welded from the factory.
May try to notch out 4 spots on the upper track to get the rivet gun in.

Maybe give some thought to some of those Hi Tech 3M or equiv. Seam Sealers & 2 part Epoxy stuff.
'Glues' have come a long way. And, dont forget - surface prep is key to proper adhesive/hold perf.

Well, after all... what would Banacek say ?... “It is only a matter of time before armed citizens, waiting or not for the police, take things into their own hands, fire on the rioters for personal and property prot. & end up hunted like dogs.”

Yeah six I was thinking construction adhesive would work. Not sure its strong enough and yes I would rough the surfaces to get tooth and clean them chemically with brake cleaner.

PL Premium wont hold to aluminum. It is a polyurethane based product and one I swear by. I did all the right things for adhesion but it still failed. I filled the inside of an 1" x 1" angle to create an airfoil on the leading edge of a steel 1 1/2' square stock roof rack I built 20 tears ago. (the square stock vibrated and hummed at highway speed)
The rack had been primed and painted which I scuffed w/ 80 grit and did the same to the aluminum. I used ratchet straps for tie downs, lots of pressure at multiple angles depending on the load and the aluminum popped off leaving the hardened PL adhesive shaped to the inside of the angle. I put another coat of paint over it and the PL stayed until I cut it off about 2 years ago. Rust had finally gotten behind it in a couple places so when I moved the rack to another truck I repainted.

definitely following this, my lower window-holding pieces are also pretty crusty.

this (quick example) is how much length I have if I insert a pop-rivet only enough for the tool to grab it. a steel tube spacer to take up the slack, and some grinding on the screw-in fitting, you might get a narrow enough arrangement to get in there. rivet guns are cheap enough, I'd butcher one if I had to.

Solder/braze?

Can you add a piece to the back? That way you can rivet them together, but separate.

Yes Matt thought of that too but trying to figure out if the extra steel will foul any of the motion. I figure do the cutouts for rivets and its really slim profile. I have had issues with clearance in the past.

Well... small edge to small edge - glue/seam sealer may not hold unless there is some holding power like from rivets, nuts and bolts or tackwelds. Maybe some raised screws holes, or protrusions (sp?).
Although the linear and radial torsional forces would be rather low - the window does not weigh that much and the window 'falls' pretty easily when lowering.
Might be better off looking at the roller diam / track inside height and the interference that might be introduced with low profile button heads and nuts.
Rivets are going to be hard to get inside the channel on either piece.

Junkyard for late model window/track - US search shows they are available. Some money may save some time.
Just saying. Look at low salt states, etc, blah, blah.

Ours here in Cinti. are rustfree - amazing, since they think salt is the 2nd cumming.

Well, after all... what would Banacek say ?... “It is only a matter of time before armed citizens, waiting or not for the police, take things into their own hands, fire on the rioters for personal and property prot. & end up hunted like dogs.”

So the issue is I don't have any junkyards around me. Plus I have a good window but no track for it. Here is what I have so far. Aluminum riveted to the stock steel regulator track.

I will next decide what adhesive will hold the glass & rubber track into the aluminum & assemble it & install it in the van.

how tight of a fit is the glass in the track? On my brothers truck we had to install a new piece of glass into the track. The track was OEM so it might be different than what you are looking at, but we used some cork gasket in the track part and lightly tapped it onto the glass. That way it was still "easily" removable.

I don't show it in the pics (but will when I do it) but the window comes with a rubber gasket that surrounds it. I am figuring silicone caulk to bond them together. It has to be bonded or the first frozen day will separate them with bad results.

Wow... looks like you have a nice handle on it.
If the bottom of the rivets is as small as usual - the roller should have no prob. getting by it.
I had them both out - never did a measurement compare.

Oh, I forgot to ask - or maybe you mentioned... Where did you get the Regulator Roller track?

Regulator track was intact from my still good window. Just the C track was perished. I had to rust reform it and prime it.
