I managed to get hold of an electric wiper motor to replace the non-working vacuum unit in my 57 BelAir. It's in great shape except for the "fiber cam" on the switch. I checked it out by manually activating the points per the repair manual and it runs fine. Only half of the "fiber cam" is there. Someone had taken it apart and I guess the broken part of the end of the "fiber cam" fell out. It's no big problem to make this piece from circuit board or other similar material, but I don't have the whole piece to use as a templet. Does anyone have one of these out at the moment that can take a stright on picture of the "fiber cam" and reply with the picture? I can take the picture in photoshop and size it to the part I have left and make an exact templet copy for my unit. I'd be glad to make more for someone that needs one if my home made one works correctly. I have tried to find a replacement piece, but I think I would have a easer time finding "Hens Teeth". Thanks all, I really want my wipers to actiually work.

I think you can purchase a new piece from the venders.

I think Bill`s refering to an internal piece
David I admire your skill in finding these pics arty0031:

Thanks all. Here is a picture of the part I need or need to make.

Good News, I Made the Part I needed

After several answered emails from people who rebuild these wiper motors, none replied that they would sell me the piece I needed. I’m not one to wait around much, so I decided to go ahead and make my own. I cut and pasted the best looking picture that had the piece I needed from the repair manual. No picture showed the whole thing, but a pictorial on one page gave the basic shape of the part I could not see. I took the photo into PhotoShop and erased the parts that I didn’t need and guest-a-mated the end I could not see. I printed out the part and compared it to the broken piece of the real thing I had left. My PhotoShop produced template was too small, so I made it bigger in PhotoShop and printed it again and again compared it to the original broken end I had. What luck, first try and it was the perfect size. I printed it out on a sheet and glued it to a piece of circuit board I had laying around that I had gotten long ago at Radio Shack. I then cut it out on my scroll saw, filed it, filed off the copper on both sides of the board material, trial fitted it, and cut a bit more of the end I guessed at, and it worked perfect. I now have a perfect working wiper motor. I also found that the resistor ceramic was broken, but the wire on it was Ok, so I super glued it together, then used JB Weld over the whole thing to strengthen it (JB Weld is non conductive). The fiber cam I made is an amazing design by General Motors. It operates the high and low speed points of the motor and toggles back and forth to start the motor and then to stop the motor at the park position. A short afternoon’s work and I now only have $80 invested in an eBay bought wiper motor setup which is cheaper than the vacuum unit cost to rebuild. Pictures of what I did attached. I hope it was Ok to post this here, and also hope I didn’t bore anyone with my story, but I like to complete a post so no one is left hanging as to what happened in the end.

In Southwest Va. where I-81 and I-77 run together for a few miles...

D.S. I've been by that way quite a few times, but never stopped for anything except food and gas. Have a great day!

Yeah, food and gas is about all that's here anyway...:sign0020:

Great to see you fixed up that motor

Good work and great pics of the step by step.

Thanks everyone, camera phones make it easy now to get pictures "as you go".
