Window Regulator Repair

#1 Post by Steve Nau »

I miss the resto strip! Wonder if this was covered in a past issue?
Closing in on the completion of my 1956 coupe restoration.
Discovered the driver side window regulator is worn such that the gears slip when you get the window about half way up.
In the attached photo you can see where the hole is worn.
Any suggestions on best way to repair?

Hard to find early regulator. Your best bet would be an excellent metal fabricator I would think. Even Jim B was sold out of early regulators a few years ago according to this post: viewtopic.php?t=44601

Probably a machinist can turn a steel bushing.
To install that bushing you will have to cut a round hole to insert the bushing and tack weld it.

That is an interesting problem and as usual the answer is to take it to a professional who can suggest and then implement a solution. That said, it is possible that it might be welded up, with a lot of skill. Or more likely, you might bush it, the problem there being making the concentric hole, something the guy doing the job would have to consider. Or you might add a partial bush.

In any event you should find a good quality moly grease.

You will probably find a fix is more than just a bush. Below is a photo of the winder side of the regulator. I would suggest you grind away the three rivets so you can see what's worn. Some welding and filing might work out and the rivets can be replaced with bolts/nuts.

Or, find a passenger side regulator (for a good price) to cannibalize the winder gear stuff. You can find a couple of those on Ebay right now. Plus, this guy in Finland makes some pieces to repair VW window regulators (same German company made both VW and Porsche regulators)

As Brad suggests - tedious hand work. Not as pretty as rivets but functional & sturdy. Certainly worth checking with Mika to see if he makes the housing that wears.

how hard could it be..
I took mine apart, had a few of the worn pieces done for me by the local machinist.
In my case it was mostly the spacer washers that were causing a lot of slop. In your picture, it is the hole that this fits into. After you grings the welds off, you doule have a washer welded in, trim it up and repaint.
it was not that hard.. a bit nerve racking making the jump to take the welds off.. then not so bad.
