Well explained Ed,
I spent more time on this window project than almost any other Healey project. Let me see if I can ad to anything Ed wrote. Eventhough he did use all the big smart words, and covered most everything in detail, I've got my dictionary here and will step up to the plate.
1. Take both guide rails out and make sure the nylon tabs will slide the entire length. Make adjustments as needed.
2. With the nylon tabs inserted in the glass frame, with the glass in the frame, slide one side of the frame down the guide rail to see if they have the same curve. Make adjustments. Do the same to the other side.
3. Install the guide rails back into the car, allowing them to have a little movement. Try and slide the window assembly down and watch where it binds up.
4. Adjustment to the back guide will be side to side only.
5. Adjustment to the front guide will be more complex.
Ad washers to the bottom to shim it out if needed.
Adjust forward or back angle. The bottom has two screws, the top where the vent is can go forward or back. Note that moving it too much forward will make the front of the vent surround hit the windshield post.
6. Check to see if back or front guides are twisted and putting pressure on the tabs. Make adjustment. (That's where my problem was).
A lot of trial and error. A lot of patience.
Now it slides up and down smoothly. Think your done?
Once you attach the crank handle bar to the guide track on the bottom of the window, does it still slide OK?
If so, consider yourself lucky.
If not, like me, take a step back, take a moment, take a breath and say #$&^@#
1. Sell the car.
2. Keep the car and clean the regulator gears and the roller at the end of the arm.
3. If the guide track on the bottom of the window is not in the right place, make adjustment.
4. An adjustment may have to be made to the regulator arm, as in bending it for proper pressure.
Now it slides up and down smoothly. Think your done?
Feeling lucky?
Install both the felt strip and the chrome finishing strip that holds the rubber weather strip on the top of the door.
Wind the window up and down. Feeling lucky?
1. Sell the car.
2. You may have to tweak the opening on top of the door to make clearance for those two pieces. I fond that flatting the black felt strip helped a little (Someone will correct my terms I'm sure. Felt?) I'm assuming your installing new rubber and felt.
Now stand back and admire your efforts. She works. And she works smoothly with a lot less effort. And this entire job only took and hour and a half. NOT. For me it was a week project. Per door. It may have gone a lot quicker if everything wasn't a figure it out as you go. Plus the down time I had combing my hair after seeing my refection in the window after every up and down trial.
Hope this helps and good luck.
Ps. wake up. Seems I went on and on, blah blah blah. You'll find this in paper back soon
