Re: Stewart's 1955 Packard 400

Over the last few month I have been working to mount a modern Dorman power window motor to my window regulators. I believe RH did the same thing in his project blog. That's where I got the idea. The difference is, I do not own a lathes and its been 30+ years since I have used one so I was not able to make some of the parts that he did.
I probably wasted $100 on parts through trial and error but I finally got it mounted and it fits in the door. I even tested it nearly 300 times before it went into the door and had no problems. I just made so many modifications that I did not bother to record much info. As I assemble the second regulator I will record what I do and post it here so, it is going to take multiple posts and some time to complete.
I have all the wiring diagrams that Howard posted to RH about the relays and more. I started out trying to use the cheapest Dorman motor I could find ($25), pictured below. I believe it's the same one RH used. I did NOT have any luck with that motor.
The gear on that motor was so large that I could not find anything to fit over it and still fit into the opening on the regulator. I then toyed with the idea that I could remove that little clip on top of the gear, remove the gear, and then use that shaft to power the regulator. As it turns out, that shaft does not turn. It is pressed fitted in the back half of the motor housing. This motor has gears within more gears to make it work.
So, I searched through the huge Dorman catalog for another suitable motor and took a chance on one. I got lucky with it and it worked. I was lucky again that it was less than $50. Many of those motors are well over $300 each.
I’ll cover all that info in future posts but the only part I really had to fabricate was the plate to mount the motor to the regulator.
