Help with Broken Window Regulator on my '62 Giulia Spider

[Alfamel]

My driver side window regulator moves the window up and down. However, the "wheel" that rolls back and forth on the window rail is worn and pops out repeatedly, rendering the window stuck in whatever position it was when the little wheel pops out.

I haven't yet found a replacement window regulator; but, mine works except for this little wheel. Can this be repaired. Does anyone know of what can be bought to be welded in as a replacement for this little, fragile part?

Help and advice, please.

I wonder if a plastic wheel for a screen door at your local hardware store might work? I haven't looked at my regulator, so I might be way off!

The real problem with this replacement is that the "wheel" mounts on an "axis" that is welded to and through the regulator arm.

I had a similar problem on my 62 spider, I turned a new "wheel" out of aluminum, works great.

This reply isn't going to be very satisfying, because despite doing some research, I haven't found your solution. But here's what I know:

Back in the mid 1990's when I restored my Giulia, I bought new replacement nylon wheels. My memory is that I got them from Centerline - certainly from one of the US suppliers, because back in those pre-Internet days, I was only buying parts domesticly. However, a quick look at the Centerline and IAP catalogs did not turn up the nylon wheels - you could do worse than calling those companies and asking if they still (or ever did!) carry them.

I also did a quick search of the British and German parts suppliers, but again came up empty. If all else fails, AFRA in Milan would be a likely source, though they are a bit difficult to deal with for so small an order.

You did not specify if the nylon wheel is your only problem, or if the shaft it mounts to is also bad. You wrote "...anyone know of what can be bought to be welded in as a replacement..." which sort of suggests that the shaft is bad too. On my Giulia, I welded standard metric bolts to the arms to form the axles. I started with a long bolt, and used a die to adjust the location of the threads so that the part the wheel rotates on is smooth/unthreaded, and there is just a short section of thread where the securing nut mounts (did that make sense?).

It is just the nylon wheel that is worn. The rest of the regulator works properly. Anyone with ideas on a source for replacement nylon wheels for the regulator?

Alfa Ricambi used to have replacement wheels, but that was some years ago.
