Again, thanks! | | | | Joined: May 2006 Posts: 92 Shop Shark | | Shop Shark Joined: May 2006 Posts: 92 | I have a 48 1/2 ton 5 window. I spent almost 2 hours on the rear window. Cant get it in. I almost get the whole window in, then the seal pops in towards the cab. I am using a flat plastic window tool. Havent even tried the corners yet. Any tricks to make this easier? | | | | | Joined: May 2007 Posts: 46 New Guy | | New Guy Joined: May 2007 Posts: 46 | You have to use cord..like window sash cord or a strong fine rope that will fit in the groove of the rubber....you need enough to go all around the glass with a foot or two left over at both ends. You need 2 people.. 1 on outside 1 on inside....Outside holds in place while inside pulls rope/cord to position rubber onto flange where it sits. Continue pulling cord slowly till it is all in place...Hope this helps...Roy

There is a trick. It involves wrapping a rope around the window rubber, putting the glass and rubber up to the hole, and while a helper holds and pushes the glass, you slowly pull the rope out.
This action lifts the lip of the rubber seal over the lip of the opening and presto, the whole thing slowly goes in. This is accompanied with a spray bottle full of soapy water applied liberally.
I did this once on a VW windshield and it worked great. Isn't the rubber on your window a two piece affair. The large piece that captures the window in the frame and a smaller wedge or 'lock' piece that expands the large one and locks it in the opening.
With the two piece rubber, you should be able to work it all in with plastic tools and soapy water. Then do the same with the lock piece...maybe not huh!

It will act as a lubricant. overlap the chord by 6 " or so. Then with a helper on the outside gently pushing, pull the chord back on itself around the window. The window will nearly fall in.
If you are using an h-channel with a lock, all that is needed is your fingers.

The correct way to fit this is to fit the rubber to the aperature and 'work' the glass into the rubber. If you go to search.. Type in; AD rear window gasket.

Soapy water didn't do it for me. Not slippery enough. I found something that worked better: waterless hand cleaner. It provided all the lubrication you'll need. Stayed put, and wiped off afterward. | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | Yes, the rubber goes on the cab first and then the glass is worked in to place. KY jelly is a great lubricant for the job. I had two little suction cups to help me hold the glass. | | | | | Joined: Sep 2005 Posts: 1,028 'Bolter | | 'Bolter Joined: Sep 2005 Posts: 1,028 | The problem I had was keeping the gasket in place while trying to get the glass in. I finally duct taped the gasket to the window all the way around on both sides. Then had 2 helpers to hold while I finessed it into place.
The biggest P.I.T.A. so far on this restoration.

You got your window in! Have you managed the lock strip? If not,try and buy an Insert tool, It'll save you no end of grief! I do this for a living,but I have to admit the first few I did in the dim and distant past were tricky to say the least! Sometimes I'd wished I had 3 hands! Well done!

Beleive it or not I seated the lock strip with a paint can opener. It was probably not as easy as the right tool but it had the correct angle and handle. It wasn't too bad. maybe about 10 to 15 minutes and it was done.
