At some point in the past my 29 tudor was switched to a vacuum windshield wiper. I plan on switching it back to an electric eliminating that problematic vacuum line. I have (picture 1) a nice intake manifold with no vacuum opening (I do not know when it was originally used, but I like the idea no place for a vacuum leak.)
When I can get them for under $40 I have been picking up electric wiper motors on eBay to take apart ( I like taking things apart!
), clean, learn how they work, and hopefully get working. I have restored the transmission of a Heinz wiper (picture 2) and found its operation to be interesting and quite beautiful. A fiber gear driven by the electric motor drives a big brass gear with a crank on the back, which in turn drives a "rack" gear which meshes with a pinion gear on the wiper shaft causing it to go back and forth.
I've got the electric motor part cleaned up and I hopefully ready to work.
So I pretty much understand how the electric wipers work. What I can't quite wrap my head around is how they are installed on the car. When mounted on the outside as I thought they were, all the the shafts including the oscillating wiper shaft point toward the inside of the car. So obviously I am confused! I would greatly appreciate any pictures or diagrams of how the electric wipers were installed and wired. Thanks in advance!
BTW I know that my primary defense against rain will actually be "Rain-X" and the electric wiper will be primarily for show, but I'd still like to get it working properly.
